OCLC has made two enhancements to WorldCat Local that impact Melvyl.  These include the following:

Support for IE10

WorldCat Local functionality, such as item availability and view now links, is now supported in IE10.  (This had been reported as a problem for UC users of the system.)

Bug fix:  Preview button display

Addresses reports of the Google preview button displaying when there were no associated previews.
