Established in 2012, the SELCO OverDrive Digital Collection is a regional collection of ebooks, audiobooks and digital magazines. The collection is a cooperative purchase, with content funded by 35 member public libraries and SELCO contributing to platform fee costs. 

SELCO provides administering the contract and the reciprocal lending agreements between RPL and TdS.

Selectors for Overdrive materials are current staff from Horizon member libraries who select materials to meet the needs and interests of the communities in the entire region.
