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 continued to appear in DC Comics publications throughout the late 1960s and 1970s as a supporting character in Detective Comics, in addition to guest appearances in various titles such as Justice League of America, World's Finest Comics, The Brave and the Bold, Adventure Comics, and Superman. In the early-1970s, Batgirl reveals her secret identity to her father (who had already discovered it on his own) and serves as a member of the United States House of Representatives. She moves to Washington, D.C., intending to give up her career as Batgirl, and in June 1972 appeared in a story entitled "Batgirl's Last Case." Julius Schwartz brought her back a year later in Superman #268 (1973) in which she has a blind date with Clark Kent, establishing their friendship, and fights alongside Superman. Batgirl and Superman team up twice more, in Superman #279 and DC Comics Presents #19.

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). Crisis on Infinite Earths, a limited series published in 1985, was written to reduce the complex history of DC Comics to a single continuity. Although Batgirl is a featured character, her role is relatively small—she delivers Supergirl's eulogy in issue #7 of the 12-part series. The conclusion of Crisis on Infinite Earths changed DC Universe continuity in many ways. Following the reboot, Barbara Gordon is born to Roger and Thelma Gordon, and she is Jim Gordon's niece and adopted daughter in post - crisis continuity. Post-Crisis, Supergirl does not
