In spite of shortcomings in her characterization during the late 1960s, "by the early 1970s, Batgirl had matured, using her keen intellect, athletic dexterity, and burgeoning detective skills to solve petty and not-so-petty thefts". Her color scheme from the Adventures of Batman cartoon are used as her primary outfit. However, by the end of the Bronze Age of Comic Books in the mid-1980s (and with the dark, gritty influence of Frank Miller's work on the Batman-related titles), Batgirl became less valuable to the franchise "where there was not as much room for a librarian fighting crime in high heels". In this environment, Barbara Gordon becomes increasingly skeptical of her effectiveness as Batgirl until she decides to give up crime-fighting permanently.

Portrayed by Yvonne Craig, the character's first adaptation outside of comic books took place in the third season of Batman (1967). Les Daniels, in Batman: The Complete History (2004) wrote that the goal of ABC was to "attract new audience members, especially idealistic young girls and less high-minded older men." According to Craig: "I used to think the reason they hired me was because they knew I could ride my own motorcycle ... I realized they hired me because I had a cartoon voice." A shared criticism of Batgirl and other female superheroes portrayed later in television (such as Wonder Woman and the Bionic Woman), is that she was not allowed to engage in hand-to-hand combat on screen. As such, "her fights were choreographed carefully to imitate the moves of a Broadway showgirl through the use of a straight kick to her opponent's face rather than the type of kick a martial Artist would use." However, Craig has also stated: "I meet young women who say Batgirl was their role model ... They say it's because it was the first time they ever felt girls could do the same things guys could do, and sometimes better. I think that’s lovely." During the early 1970s, Craig portrayed Batgirl once again in a public Service announcement to advocate equal pay for women. Since Batman, the character has had a long history of appearances in television and other media. As Batgirl, Barbara Gordon plays a supporting role in a string of animated series, voiced by Jane Webb in The Batman/Superman Hour (1968), Melendy Britt in The New Adventures of Batman (1977), Melissa Gilbert in Batman: The Animated Series (1992), Tara Strong in The New Batman Adventures (1997) and Beware the Batman (2013), Danielle Judovits in The Batman (2004), Mae Whitman in Batman: The Brave and the Bold (2008) and Alyson Stoner in Young Justice (2011). The Batman series also showcased the character's first animated adaptation as Oracle, voiced by Kellie Martin in the episode "Artifacts" (2007). She also appears in DC Super Hero Girls voiced by Mae Whitman in season 1 as Barbara Gordon and season 2 as Batgirl. Other variations of the character that have been adapted into other media include an elderly Barbara Gordon, voiced by Stockard Channing and Angie Harmon in 1999's Batman Beyond, who after retiring as Batgirl, became commissioner of the Gotham City police department.

In her civilian identity, Barbara Gordon, Ph.D., is depicted as a career woman with a doctorate in library science, as well as being head of Gotham City public library, "presumably one of the largest public libraries in the DC Comics version of reality." She was given a regular backup slot in Detective Comics starting with issue #384 (February 1969), alternating issues with Robin until issue #404, after which she had the backup slot to herself. Frank Robbins wrote nearly all of these backups, which were penciled first by Gil Kane and later by Don Heck. Barbara Gordon’s Batgirl exceeded the earlier Bat-Girl and Batwoman characters in popularity, and readers requested for her to appear in other titles. Although some readers requested that Batwoman also continue to appear in publication, DC responded to the fan-based acclaim and criticism of the new character in an open letter in Detective Comics #417 (1971), stating: "I'd like to say a few words about the reaction some readers have to Batgirl. These are readers who remember Batwoman and the other Bat-girls from years back ... They were there because romance seemed to be needed in Batman's life. But thanks to the big change and a foresighted Editor, these hapless females are gone for good. In their place stands a girl who is a capable crime-fighter, a far cry from Batwoman who constantly had to be rescued [by] Batman."

Batgirl also guest-starred in other Superman related titles such as Adventure Comics, and in Superman Family #171, where she teams with Supergirl. The character is given a starring role in DC's Batman Family comic book which debuted in 1975. The original Robin Dick Grayson became her partner in the series and the two were frequently referred to as the "Dynamite Duo: Batgirl & Robin." Batgirl meets Batwoman in Batman Family #10, when the retired superhero briefly returns to crime-fighting (before Kane is murdered by the Bronze Tiger). The two fight Killer Moth and Cavalier, and learn each other's secret identities. Batwoman retires once again at the conclusion of the story, leaving Batgirl to continue crime-fighting. Although this series ended after three years of publication, Batgirl continued to appear in back up stories published in Detective Comics through issue #519 (October 1982).

In the 1980s, Barbara Kesel, after writing a complaint to DC Comics over the negative portrayal of female characters, was given the opportunity to write for Barbara Gordon in Detective Comics. Robin Anne Reid, in Women in Science Fiction and Fantasy: Overviews (2009), wrote that "Kesel's version of Batgirl established her as a character separate from Batman and Robin: a woman motivated to do what men do, but alone and in her own way. Her Secret Origins (1987) and Batgirl Special (1988) countered the victimized and objectified presentation of Barbara Gordon/Batgirl in Alan Moore's acclaimed The Killing Joke (1988)." She notes that Kesel's interpretation of the character emphasized her intelligence, technological skill, and ability to overcome fear. Commenting on Barbara Gordon's eventual evolution into Oracle, she states "[m]any readers and individuals within the industry believe that Barbara Gordon became a 'better' character after she was paralyzed, but few people comment on specifics of the event that allowed her to become that 'better' character."

Various alterations of the Barbara Gordon character have appeared in storylines published in and out of mainstream continuity titles. Variants of the character within continuity often appear in stories which involve time travel, such as the crossover limited series Zero Hour: Crisis in Time, a follow-up story preceded by the 1985 limited series Crisis on Infinite Earths which altered mainstream continuity. Notable imprints of DC Comics such as Elseworlds and All Star DC Comics have also featured alternate versions of the character.

DC officially retired the hero in the one-shot comic Batgirl Special #1 (July 1988), written by Barbara Kesel.

Yale and Ostrander oversaw the development of Barbara Gordon's new persona as Oracle for the next several years. The character made her first comic book appearance as Oracle in Suicide Squad #23, anonymously offering her services to the government's Task Force X. In the following two years, Oracle, under pen of Ostrander and Yale, made guest appearances in various DC titles until her identity was revealed to be Barbara Gordon in Suicide Squad #38 (1990) and she officially becomes a member of the Squad in issue #48 following an invitation from Amanda Waller. In 1992, Dennis O’Neil wrote Oracle as Batman’s sole source of information in Batman: Sword of Azrael #1. This newly forged partnership established Oracle’s status as Batman's intellectual equal. She is subsequently featured in the 12-issue miniseries The Hacker Files (1993). In "Oracle: Year One"—a story arc contained in The Batman Chronicles #5 (1996)—Yale and Ostrander tell the origin of Barbara Gordon's new persona as Oracle. Initially, Gordon's paralysis plunges her into a state of reactive depression. However, she soon realizes that her aptitude for and training in information sciences have provided her with tremendous skills that could be deployed to fight crime.

Gail Simone would include the character's paralysis in a list of "major female characters that had been killed, mutilated, and depowered", dubbing the phenomenon "Women in Refrigerators" in reference to a 1994 Green Lantern story where the title character discovers his girlfriend's mutilated body in his refrigerator.

Barbara Gordon, as both Batgirl and Oracle, has made several appearances in Elseworlds comics since 1997. The Elseworlds imprint takes the company's iconic characters and places them in alternate timelines, places and events making heroes "as familiar as yesterday seem as fresh as tomorrow." The character is given starring roles in the noir-style storyline Thrillkiller: Batgirl & Robin (1997), its sequel Batgirl + Batman: Thrillkiller '62 (1998), and the one-shot comic Elseworld's Finest: Supergirl & Batgirl (1998), all of which depict worlds where Barbara is Gotham's first bat-themed hero (Bruce Wayne is a police detective who becomes Batman in the 1960s-set Thrillkiller series, and merely serves as essentially her 'Alfred' in Elseworld's Finest in a timeline where Jim Gordon was killed rather than the Waynes).

In addition, the character has supporting roles in JLA: The Nail (1998), JLA: Created Equal (2000), Superman & Batman: Generations (2003), Batman: Year 100 (2006), and Batman: Earth One (2012). A version of her appears as "Nightwing" in the Smallville comic series, replacing Stephanie Brown as previously promoted.

Dina Meyer starred as Barbara Gordon in the television series Birds of Prey (2002). It became the first adaptation to show the character's progression from Batgirl to Oracle, which included her paralysis at the hands of the Joker. Meyer commented on her character's complex history stating: "She's multidimensional. She was a former superhero. She was extremely active physically for years, fighting alongside Batman. The unfortunate incident with the Joker took away the use of her legs ... but rather than give up and throw in the towel, as she could've done so easily, she went and studied escrima (a martial art), got stronger in her mental state and, while helping out her father on a case one day, realized she had a knack for solving mysteries. And all of a sudden she became this computer genius." Overall, the series received criticism for its emphasis on aesthetics over plot. It aired for one season before receiving cancellation. In the fourth season of the TV series Arrow, after Felicity Smoak suffered a similar paralyzing injury, Oliver Queen gives her the codename Overwatch while commenting that "Oracle" was taken. Although, in the comic books Barbara Gordon was never a member of the Teen Titans she was slated to appear in the live-action Titans series for TNT. This version of the character will be a wheelchair-bound computer expert, but will not yet be known as Oracle. This series has since been abandoned

Over the years, the American Library Association and DC Comics have collaborated on multiple projects to promote literacy. These efforts frequently involve Barbara Gordon. In 2004, Artist Gene Ha created a poster and bookmark that depicted Barbara Gordon walking in a library. Her Batgirl costume appears in a window's reflection. The tagline "Librarians are heroes every day!" appears at the bottom of the poster and bookmark. In 2009, a poster featured Barbara Gordon as the Oracle alongside Batman, Nightwing, Robin, the Cassandra Cain version of Batgirl, and Huntress. In 2015, the ALA and DC Comics collaborated on a new set of posters and bookmarks in the ALA's "READ" campaign. By herself, Barbara Gordon appears in the "Batgirl of Burnside" guise as envisioned by Babs Tarr. In another design, she appears as the Oracle alongside other members of the extended Bat Family.

An alternate Barbara Gordon was adapted into Frank Miller's All Star Batman and Robin the Boy Wonder (2005) as a teenage Batgirl. In addition, another variation of the character had been set to star in an eponymous All Star Batgirl title, written by Geoff Johns; however, the series was canceled prior to publication.

In "Whitewater", Gail Simone's final story arc on Birds of Prey (2007), Oracle and her team struggle for power with Spy Smasher, a government agent who has taken over the Birds of Prey organization. Eventually, Spy Smasher is forced to admit her defeat and returns control of the Birds of Prey organization to Oracle. At the conclusion of the arc, Oracle also adopts Misfit into the Birds of Prey. Sean McKeever temporarily took over as author of Birds of Prey, writing issues #113–117, Birds of Prey: Metropolis or Dust (2008). The following arc of the series Birds of Prey: Platinum Flats (2008) is written by Tony Bedard. In the company-wide 2008 Final Crisis storyline, Darkseid—who has finally gained control of the Anti-Life Equation—attempts to put the mind-control equation on the internet. Both Oracle and Mister Terrific make desperate attempts to stop Darkseid, even attempting to shut down the entire Internet. Unfortunately, they both fail and those affected ended up mindless slaves of Darkseid. Freed from Darkseid's control after the restoration of the Multiverse, she attempts to shut down the Criminal Unternet set up by her opposite number, the Calculator, as a Darkseid-free replacement for the regular Internet and still used by tech-savvy Criminals. However, the Calculator, preventing her moves, takes control of the Kilg%re, gaining the ability to thrive in cyberspace by controlling digital and cybernetic avatars, and tracks Oracle down with his newfound powers. Even though Oracle foils him, she starts doubting her abilities and fears she's losing her edge and brilliance, which results in her disbanding the Birds of Prey team to do some soul-searching. Birds of Prey received cancellation in early 2009, with the final issue being #127.

In addition to live-action television and animation, the character has appeared in a number of video games included in the Batman franchise. She appears in The Adventures of Batman & Robin, Batman: Vengeance, Batman: Rise of Sin Tzu and Batman: The Killing Joke voiced by Tara Strong. She is also in Batman: Dark Tomorrow for the first time as Oracle. She also appears in LEGO Batman for the PC, PlayStation 2, PlayStation 3, Xbox 360, Wii, DS, and PlayStation Portable. She plays a supporting role as Oracle in Batman: Arkham Asylum for the PC, PlayStation 3, and Xbox 360, serving as Batman's guide through Arkham, and is voiced by Kimberly Brooks. She also appears as the radio guide alongside Alfred Pennyworth, as they both serve as Batman's guides in the sequel, Batman: Arkham City. A teenage Barbara also appears in the prequel Batman: Arkham Origins, voiced by Kelsey Lansdowne. In the 2008 live-action film, The Dark Knight, a very young Barbara Gordon is depicted. She is credited as "Gordon's Daughter", while the name "Barbara Gordon" is reserved for Commissioner Gordon's wife. She also acts as the primary contact for hero characters as Oracle in DC Universe Online, voiced by Katherine Catmull for the PC and the PlayStation 3. She assists the player through the tutorial and will offer comments and advice throughout the game including a guided tour of the JLA Watchtower. She is a playable character in Injustice: Gods Among Us, with Kimberly Brooks reprising her role. Barbara has returned in Batman: Arkham Knight where she is voiced by Ashley Greene. In addition, Barbara also appears as a playable character as part of the game's season pass.

In The Supergirls: Fashion, Feminism, Fantasy, and the History of Comic Book Heroines (2009), author Mike Madrid states that what set Barbara Gordon as Batgirl apart from other female characters was her motivation for crime-fighting. Unlike Batwoman who preceded her, "she wears his symbol on her chest, but she is not his girlfriend or faithful handmaiden." Because she does not pursue a romantic interest in Batman, "Batgirl is a female Batman can actually regard as a brilliant peer and a partner in the war on crime, the same way he would a male." Historian Peter Sanderson observed that while "Barbara Gordon initially conformed to hackneyed stereotypes as a dowdy librarian ... her transformation into Batgirl could be seen in retrospect as a symbol of the emerging female empowerment movement of the 1960s. (Moreover, by the 1970s Barbara had given herself a makeover even in her 'civilian identity' and ran for Congress.)"

In Superheroes and Superegos: Analyzing the Minds Behind the Masks (2010), author Sharon Packer wrote that "[a]nyone who feels that feminist critics overreacted to [Gordon's] accident is advised to consult the source material", calling the work "sadistic to the core." Brian Cronin noted that "[many] readers felt the violence towards Barbara Gordon was too much, and even Moore, in retrospect, has expressed his displeasure with how the story turned out." Jeffrey A. Brown, author of Dangerous Curves: Action Heroines, Gender, Fetishism, and Popular Culture (2011) noted The Killing Joke as an Example of the "inherent misogyny of the male-dominated comic book industry" in light of the "relatively unequal violence [female characters] are subjected to." While male characters may be critically injured or killed, they are more than likely to be returned to their original conception, while female characters are more likely to receive permanent damage. Reid states that although speculation behind the editorial decision to allow the paralysis of the character to become permanent included the idea she had become outdated, "if audiences had grown tired of Batgirl, it was not because she was a bad character but because she had been written badly."

As part of DC Comics' 2011 relaunch, The New 52, Barbara Gordon's paralysis is described as lasting only three years time. In Batgirl (volume 4), the character's age is reduced, and she is depicted as a recent college graduate, having earned a degree in forensic psychology. Although she resumes her work as Batgirl one year after recovering her mobility, she continues to suffer from posttraumatic stress disorder, causing her to hesitate in battle when exposed to gunfire that could result in receiving new spinal damage. The character also exhibits survivor guilt due to the fact she has made a full recovery from her paralysis while others have not. In a September 2011 interview, Gail Simone stated, "I'm enjoying writing Batgirl at this stage in her life. She's younger, she doesn't know everything, she's been immersed in school and her life-plan. Events conspire to change that plan, and she's nervous about that. I love writing Barbara under pretty much any conditions, but this really is a key time for her." In Batgirl #45, Barbara Gordon began a romantic relationship with Luke Fox, the son of Lucius Fox and the new Batwing. Some of the character's background and previous relationships were erased. According to the Artist of the new Batgirl series, Babs Tarr, Barbara Gordon and Dick Grayson were never romantically involved in the New 52 continuity.

According to the character's fictional biography, Barbara Gordon trained in Judo, Kung Fu, Eskrima, Karate and Jujutsu, earning black belts prior to her tenure as Batgirl and is described as being a "star athlete." Following the events of The Killing Joke, Barbara Gordon continued to train in martial arts as Oracle, despite being paralyzed from the waist down. She has extensive skills with eskrima fighting sticks, small firearms, and batarangs; she customarily keeps a pair of eskrima sticks stored in the armrests of her wheelchair as a contingency. In the revised continuity of The New 52, she reflects on the fact that she has been taking self-defense training since age six in Batgirl #0 (2012).

Reacting to The Killing Joke and Barbara Gordon's later character development as Oracle in Batman: Gotham Knights, Ray Tate, a reviewer at Comics Bulletin, wrote "[t]here is absolutely no reason why Barbara Gordon should be in a wheelchair. Alan Moore and Brian Bolland meant The Killing Joke as an imaginary tale dealing with the iconography of Batman and the Joker ... [Batman] himself is a certifiable genius in biochemistry. There are countless examples of Batman employing that which is only theoretical in his fight against crime. His knowledge of stem cell Technology should surpass that of the real world. There is simply no reason for Barbara Gordon to be confined to that wheelchair." Regarding her representation as a character living with a disability, and her effectiveness as a hero compared to her incarnation as Batgirl, Tate asserts "[i]t's ridiculous to think somebody wakes up thinking how lucky they are to be confined to a wheelchair, and yet the attitude around DC and among the fans is that Oracle is the better character over Batgirl because of her handicap. Rubbish. Batgirl has fought more crime and done more to aid Batman as Batgirl than she has as Oracle. Batgirl has saved Batman's life on numerous occasions. Oracle has not. Barbara in this incarnation is not a bad character, but she is not better because she no longer hunts the night in cape and cowl." In an article for Bitch magazine entitled "The Cold Shoulder: Saving Superheroines from Comic-book Violence", Shannon Cochran noted a long history of inequality regarding the treatment of female heroes. She quotes Gail Simone, who discussed the gender difference regarding the treatment of Batman and Batgirl regarding paralysis: "Both had their backs broken [Batman broke his in a dramatic Batcave confrontation with the villain Bane; Batgirl broke hers when she was ambushed in her home and shot in the spine by the Joker, never given a chance to fight]. Less than a year later, Batman was fine. Batgirl—now named Oracle—was in a wheelchair and remained so for many years."

On March 13, 2015 DC Comics released 25 Joker-themed variant covers for its various monthly series for release that June, in celebration of the character's 75th anniversary. Among them was a cover to Batgirl #41 by Artist Rafael Albuquerque that took its inspiration from The Killing Joke. The cover depicts the Joker standing next to a tearful Batgirl, who has a red smile painted across her mouth. The Joker has one hand holding a revolver draped over Batgirl's shoulder and is pointing to her cheek with the other hand, as if gesturing to shoot her.

For DC's 2016 DC Rebirth launch, Barbara Gordon headlines two monthly series: Batgirl and Batgirl and the Birds of Prey. Batgirl, which is written by Hope Larson and illustrated by Rafael Albuquerque, begins with Barbara touring Asia to train with eastern fighters. Batgirl and the Birds of Prey, which is written by Julie and Shawna Benson, and is illustrated by Claire Roe, reunites her with former teammates Black Canary and Huntress (Helena Bertinelli). The first arc of the series restores her prior history as "Oracle", as the team works to track down an imposter using the alias. In the DC Rebirth continuity, Barbara continues to operate in Burnside after training in Asia. She also shows a renewed romantic interest in Dick Grayson, but is unsuccessful due to him already being in a relationship.

Barbara Gordon appears in the 2017 animated film The Lego Batman Movie voiced by Rosario Dawson. She is introduced taking over from her father Jim Gordon to become the new Police Commissioner of Gotham. This allows for the continuation of still having a ‘Commissioner Gordon’ and gives a more prominent role to the character. She later dons her cowl and teams up with Batman as Batgirl in addition to her role as Commissioner. In March 2017, it was announced that Joss Whedon was in talks to write, direct and produce a Batgirl film as part of the DC Extended Universe. The film would center on Barbara Gordon, with The New 52 comics by Gail Simone serving as "a starting point" for the film.

Prior to release, Batgirl #1 sold out at the distribution level with over 100,000 copies printed in its first run according to Diamond Comic Distributors. Along with Action Comics #1, Justice League #1, Batman #1, Batman and Robin #1, Batman: The Dark Knight #1, Detective Comics #1, Flash #1, Green Lantern #1, and Superman #1, Retailers were required to order a second printing. Calvin Reid of Publishers Weekly states in a review of the first issue: "The artwork is okay though conventional, while Simone’s script tries to tie up of the end of the previous Barbara Gordon/Oracle storyline and setup up the new Batgirl. Her formula: murderous villains, blood splattering violence and high flying superheroics mixed with single-white-female bonding ... plus a cliffhanger ending to the first issue that offers a nifty [segue] into the new world of Barbara Gordon and Batgirl." The New York Times critic George Gene Gustines wrote: "Unlike some of the other DC comics I read this week, Batgirl achieves a deft hat trick: a well-shaped reintroduction to a character, an elegant acknowledgement of fundamental history and the establishment of a new status quo. This is a must-buy series." Earning a B+ rating in a review from Entertainment Weekly, Ken Tucker writes that Simone "[takes] her Birds of Prey storytelling powers and focuses them on the newly revived Barbara Gordon as Batgirl. The result is a burst of exhilaration, as Barbara/Batgirl revels in her new freedom even as she encounters a so-far not-terribly-chilling villain called Mirror."
