Controlled Digital Lending as it pertains to libraries is an idea that is laid out in the whitepaper linked below:
Controlled Digital Lending Whitepaper
The White paper argues that it should be lawful for a library who owns a copy of a title to lend that title digitally on a one to one basis, meaning, if the item is being loaned digitally, the physical copy is inaccessible for lending and visa versa. Further, the digital copy should not be downloadable by the patron and only those persons associated with the library that owns the physical copy should be able to access it.
Controlled Digital Lending as described in the whitepaper above is not established law and the lawsuit that most recently tested this argument, Hatchette v. Internet Archive, was decided in favor of the publishers on March 24th, 2023. Internet Archive says that they will appeal. Any library that would like to pursue CDL with works still under copyright should consult with their institution's legal team before doing so.

If you have administrator rights you can do this yourself, Jenna does a great job at detailing this. If not you can submit a ticket to the help desk to have them created for you.
An Access Rule can:
It is also possible to add a copyright statement.
