OhioLINK is in the final stages of migrating all of the content from their Digital Media Center (DMC) into their Digital Resource Commons (DRC). This content includes two statewide databases: the ART Collection and the Sanborn maps. On August 15th the DRC will be the official platform for these collections, and at the end of the month, the DMC will be decommissioned.
If you are using the OPLIN "shortcuts" to these databases ( [ http://www.oplin.org/art or http://www.ohioweblibrary.org/art ] and [ http://www.oplin.org/sanborn or http://www.ohioweblibrary.org/sanborn ] ), then you don't need to do anything. OPLIN has already changed those links to point to the DRC.
If you use your own links and authentication system to access these databases, then you will need to change your target URLs:
Again, you only need to worry about this if you are not using the OPLIN shortcuts.
