A colleague of mine forwarded this presentation by James Michalko from OCLC to me. The presentation was done at the Keio Symposium earlier this month. One of James’ slides, based on data from the US Department of Education, NCES Academic Library Survey 1998 – 2008, shows projections that academic library expenditures on purchased and licensed content will by 80% ebooks and ejournals by the year 2020. Comparing this to the charts figures from 1998 are staggering. In 1998 only 10% of expenditures were electronic. OCLC has a page with a variety of presentations from their staff members. It’s worth a look, plenty of good data and projections.
