Pumerantz Library provides access to e-books from a number of providers—MD Consult, Access Medicine, Ovid, R2 Digital Collection, and STAT!Ref, to name a few. The library strives to offer the best mix of titles based on availability and affordability, but this can mean that only a limited number of users may be able to access an e-book at the same time. Depending on the title, access is provided to an unlimited number of people, only one person at a time, or somewhere in between. We monitor the usage of our e-books, as well as how often users get “turned away.” We also respond to access problems reported by our users. When possible, we may purchase additional “copies” of a title to allow more users to have simultaneous access.
