In the perception of literary scholars, the investigation of genre histories is still closely linked to ‘offline’ archival work. However, the Internet has been publicly accessible since 1991, and over the last thirty years, numerous new literary genres have emerged. They have often been proclaimed, defined, spread, marketed, criticized, and even pronounced dead online. By now, a great deal of this digital material is said to have disappeared. What many scholars do not consider, however, is that parts of the web are archived, for example by the Internet Archive and Wikipedia, which make their archives publicly available via the Wayback Machine and the history page respectively. This makes it possible to track early online definitions of contemporary genres and their development. In this paper, I will use the chick lit genre, which emerged in the second half of the 1990s, as a case study to show the benefits of including web archives in the reconstruction of contemporary genre histories. An analysis of both the first extensive and long-running fan websites, which are now offline but well-documented in the Internet Archive, and the history page of the Wikipedia article on chick lit will challenge some of the narratives that have long dominated chick lit research.
