The UW System will be going through an upgrade of the joint catalog system and UW System borrowing will be unavailable for most of August.
PantherCat (UWM's catalog) is expected to be in 'read only' mode from 7-9 Aug.
You'll be able to search for books, but the item-availability status may be incorrect since the database can't be updated to reflect currently checked out materials during this period. You also will not be able to renew any materials.
Full details are available at the Libraries' website http://www4.uwm.edu/libraries/News/panthercat_upgrade12.cfm
PLEASE NOTE: The Library, including the Music & Curriculum Library will be open. You may still check out and return materials.
