From the State Library:
In the interest of bringing the best service to our customers, the Iowa library community, we have merged the two existing downloadable eBook and audiobook consortia, WILBOR and NEIBORS, into one system. We have named this new consortium “Bridges: Iowa’s eLibrary”. It will provide the same eBook and audiobook service that you have come to expect from OverDrive. Iowa Library Services has signed a 6 year contract with OverDrive to provide this service. We anticipate Bri dges will launch by July 20, 2015. Both NEIBORS & WILBOR sites will be fully functional until then. There will be no gap in service.
