Three Main Economic Models
Subscriptions from publishers (transitioning to leases) 2. Pay-to-publish by publishers (“open access publishing”) 3. Subsidized by institutions or individuals (without traditional publishers)
33
With Traditional Publishers
Society Publishers % Commercial Publishers 40% Other % Educational %
34
Library Owning vs. Borrowing Article Copies
Institutional Subscriptions Break-Even Point ILL/Document Delivery
35
Subscribing vs. Separate Copies
Institutional Price Break-Even Point in Number of Readings $100 9.5 $150 12.1 $250 17.3 $500 30.4 $1,000 56.5
36
Library Subscription Prices
Institutional Price Proportion of Journals to which Libraries can Economically Subscribe $100 88.9 $150 84.6 $250 78.2 $500 65.5 $1,000 49.0
37
Open Access Publishing
Author or institution pays Typically $500-$2000 (U.S) per article “Memberships” BioMed Central Public Library of Science
38
Without Traditional Publishers
Institutional Repositories (“University Archiving”) Self-Archiving E-Print Service (e.g., arXiv.org)

Sources of Readings Scientists appear to be reading from
% and amount of readings from separate copies use of personal subscriptions Scientists appear to be reading from more journals—at least one article per year from approximately 23 journals, up from 13 in the late 1970s and 18 in the mid-1990s.
