OverDrive proudly works with over 50 UK publishers that license eBooks to UK public libraries for lending via remote download. Since the inception of the service over 6 years ago, slightly over 14,000 total eBook units serving public library authorities in Great Britain, Scotland, and Ireland have been licensed through OverDrive. The average circulation is 2.9 check outs per title. As the service grows in popularity, circulation will increase. But so will the number of units, thereby keeping the circulation per title relatively constant.
