'The Eros Collection at Flinders University is the largest collection of materials produced by the sex industry and its affiliates in Australia. Acquired in 1997 and added to over the years, the varied collection (now part of the umbrella Australian Sexuality Collection) includes restricted or censored audiovisual and print materials – in short, porn. Thus this archive – typically a site of protection and care – comprises materials that many people think don’t deserve protection, and this ambiguous status has raised many challenges in terms of how the Collection is valued, researched, and utilized. The thorny question of the Collection’s value is traced in our research through interviews with Special Collections librarians involved with the Collection over different periods and an audit of Collection contents, access, and usage, which we analyse within the broader context of international porn archives and Australian media histories. The article examines how the Collection (specifically its pornographic material) shares key challenges faced by porn archives internationally, including public perception and access, and its uneasy fit within the Australian media histories. We argue that this neglected archive holds promise for understanding porn’s place in Australia’s audiovisual and cultural history.' (Publication abstract)
