From a101cd2d8232c57ccb47b6f89547bf684d49f91c Mon Sep 17 00:00:00 2001 From: Joe Atzberger Date: Wed, 28 May 2008 20:31:28 -0500 Subject: [PATCH] Tags AJAX integration on OPAC details page, so it behaves like results. Also, prevent duplicate tags (same user, biblio and term). Strip leading/trailing whitespace from term. Block whitespace terms. The CSS for details could be enhanced to emphasize tagstatus more.
