  20. 20. Subscribed Collections Summary• 33% Ebrary : 27% in Common : 40% EBSCO• Ebsco’s advantage comes from older ebooks • 1980-1999• Many publishers subscription ebooks are only available through one aggregator • Ebsco – ABC Clio, Nova Science, J. Benjamin, SAGE, etc. • Ebrary – Nat. Acad., Oxford, Palgrave, World Bank, etc.• Subject coverage is relatively similar
  21. 21. Subscription cost less than a penny on the dollar per year!Subscribable Ebrary Ebooks = 77,482 purchase price $5,670,776 (single-user price)≤ $3.75/FTE… so for 5000 fte = $18750/year% of list price per year = 0.33% (multi-user price)Years to buy = 300+ years! Ebsco subscription pricing is similar…Q.E.D. If you are investing in aggregator ebooks,you should seriously consider both subscriptionpackages, and avoid buying individual books thatare (or will be!) available by subscription…

  25. 25. EbookMarketplaceis only 1/3 as large as Hathi for 2000-09 books
  26. 26. Google books casts an even longer shadow
