At the 2019 ALA Annual Conference, I learned about the Controlled Digital Lending Program, which 37 libraries have implemented thus far.  On January 30, the Board of the Chief Officers of State Library Agencies (COSLA) endorsed the position statement on this program.  What is controlled digital lending? Their press release says:

Originating conceptually from the copyright community and pioneered by the Internet Archive through their Open Libraries program, Controlled Digital Lending (CDL) allows libraries to digitize older in-copyright print books. In this ‘lend like print’ model, participating libraries choose to circulate either the print or the digital copy of a title. The model supports libraries in making 20^th century materials available digitally while respecting copyright laws. The Internet Archive has been circulating a collection of over one million books using this model since 2008.

The press release contains more information and I've placed a resource list below.  If you are interested in digitally circulating your older in-copyright print books, I encourage to you look into this.
