Controlled Digital Lending (CDL) is a strategy for restricting access to digital material based on corresponding physical copies held by an institution.

When CDL is enabled for an Avalon collection, each item can only be viewed after a user borrows the item, and an individual item can only be borrowed and streamed by a single user at a time. Only authenticated (logged-in) users are able to borrow items.

Enabling CDL in Avalon Media System

To enable CDL in Avalon, update the configuration file for your Avalon installation. The CDL panel on the collection administration page below will not appear until CDL is enabled in the application-wide settings.

Enabling CDL for Collections

To enable CDL for a collection, check the “Enable controlled digital lending for this collection” box on a collection’s administration page and select the corresponding Save button:
