Understanding EBook Access Model
Note: To ensure permanent access to a particular title, a purchase is required. If you wish to use or confirm access to an eBook for a course, please request its purchase through the Copyright Office.
Perpetual eBooks are owned by Libraries and Cultural Resources (LCR). This means that LCR has purchased a copy and has perpetual rights to that eBook. In most cases, this is a single user copy unless a course purchase is made for simultaneous user access. These titles are loaded into the Classic Catalogue.
Accessible not owned
The eBook titles available in the following three models can fluctuate, since such titles do not remain permanently available when purchased through a package.
EBook packages are subscribed to on an annual basis. These are very cost effective as thousands of books can be available to users for a very low cost per use. These packages are subject to publisher removal of individual book titles at inconvenient times. LCR does not purchase individual titles unless a request is made.
- Demand Driven Acquisitions (DDA)
EBook titles are not owned by LCR, but records for the eBooks are provided for users using SEARCH (Summon, not the Classic Catalogue). If someone uses the eBook multiple times, a purchase is triggered and it becomes a Perpetual eBook. Publishers frequently add and subtract individual book titles from DDA.
- Evidence-Based Acquisitions
These are a hybrid between perpetual and subscription eBooks. In May 2016, we initiated our first evidence-based acquisitions subscription - with University Press Scholarship Online (Oxford University Press). This arrangement provides access to approximately 20,000 academic eBooks for one year. At the end of the year, we will be required to purchase a small percentage of the collection. The eBooks we purchase will be owned perpetually. If we renew the subscription, we will retain access to the initial collection for the renewal period, as well as receive access for those titles added for the renewed subscription period. At the end of the renewal, we will again be required to purchase a minimum percentage from the collection.
