Butler Libraries provide access to many different kinds of ebooks, with varying access models depending on the ebook provider. Please use the guidance below to determine what level of access is available for a particular ebook.
Ebooks available on the following platforms always have unlimited user access:
Note: This is not an exhaustive list.
Determining the access level of an ebook on ProQuest Ebook Central may take a few steps, depending on the ebook. This is because ProQuest licenses ebooks at varying access levels, and because Butler Libraries has both a Demand Driven Acquisition (DDA) plan and a subscription ebook collection through Ebook Central.
On this platform, you can find ebooks that the library has licensed at the following levels:
You will also find ebooks that the library has not licensed yet, but are part of our DDA pool. Ebooks in the DDA pool are either mediated (i.e. request required for purchase) or unmediated (i.e. no request required, a purchase is automatically made after a certain amount of use).
Check the "Availability" section at the top an ebook's page in Ebook Central to help determine the access level.
| Message under "Availability" | Access level | Notes |
| Your institution has access to 1 copy of this book. | 1-user access | |
| Your institution has access to x copies of this book. | x-user access | Usually 3-user, but could be a different number if multiple 1-user or 3-user licenses were purchased. |
| Your institution has unlimited access to this book. | Unlimited user access | |
| Your institution has access to multiple copies of this book. | Nonlinear access OR unlicensed DDA access | Check the ebook's record in the library catalog to determine if the book has already been licensed. Scroll down to where it says "Access Online" at the bottom of the record. Underneath the ebook's title next to the "View eBook" link, there will be the name of the collection that the ebook link is coming from. If the ebook is part of our DDA pool, then the collection will be "Ebook Central DDA". If it has already been licensed, they you will see "Ebook Central Perpetual Titles". |
