Open access is displacing interlibrary loan.
See the slide presentation given by the US National Library of Medicine (NLM) at the 2014 conference of the Medical Library Association. The slides report the results of a survey of users of DOCLINE, the NLM's interlibrary loan (ILL) service. Unfortunately, the slides are are download-only PowerPoints, and not displayable through the browser. http://www.nlm.nih.gov/docline/presentations/MLA_2014_DOCLINE_Update.pptx
Slide 34 shows that OA is the leading cause
of the decline of ILL. Slide 36 shows that for these heavy ILL users, OA is the 2nd most common method for obtaining new literature, after ILL itself. The publisher's web site is 5th, the author 6th, and pay-per-view 8th. ILL and OA are the only two methods used by more than 10% of respondents.
