Previous Versions

MarcEdit 4.5.9397 -- Download MarcEdit 4.5 Update 3 Now
Added: MarcEdit 4.5 Update 3 is a full, updated version of MarcEdit 4.5+. This version supersedes all previous versions. To see what's been corrected or changed in Update 3, please see the Change Log.
MarcEdit 4.5+ is probably my most ambitious upgrade to date. Over the past year and a half, I've implemented a native Z39.50 client, XML API and Unicode support for the MarcEditor. This upgrade represents a major improvement to the MARCEngine's traditional MARC functionality, in addition to the inclusion of an XML API which will allow any user to create their own data crosswalks.

However, no further patches will be issued for MarcEdit 4.1. MarcEdit 4.5 is now the current developmental version of MarcEdit.
