The MOD Editorial Committee and the Library of Congress is pleased to announce that a new incremental version of MODS, version 3.5, is now available on the MODS website at:

This revision is backwards compatible to version 3.4 and therefore only includes changes that do not result in invalidating existing MODS records. A new major revision of MODS to make more substantive changes is currently under discussion. MODS implementers may want to use this revised version to take advantage of its new features. The changes are as follows: 

For further information and examples see: Revised versions of the MODS User Guidelines, the MARC to MODS mapping, and the XSLT conversion that incorporate the 3.5 changes will be available on the MODS web site soon.

Please direct any comments or questions on the MODS 3.5 Schema, or MODS/MADS developments in general, to the MODS Listserv <>.
