NetLibrary, OCLC's platform for econtent, intends to offer downloadable eAudiobooks from Blackstone Audio through subscription as well as its current purchase program beginning March 3, 2008. Through an expanded partnership with Blackstone Audio, a producer of unabridged audiobooks in the United States, NetLibrary will offer libraries an extensive collection of 1,800 eAudiobook titles available on a subscription basis. Approximately 15 to 25 new titles will be added to the collection each month at no additional cost. Key subject areas in the Blackstone eAudiobook collection include Fiction and Literature, Biography, Business, Religion, Philosophy, Science Fiction, Non-Fiction, Mystery, and Suspense. The subscription is delivered under a simultaneous, multi-user access model. Any number of patrons can access the same eAudiobook title at the same time through the internet. Users will have the ability to check out and download up to 10 titles at one time for a period of 21 days.
