The MODS/MADS Editorial Committee and the Library of Congress are pleased to announce a new version of the Metadata Authority and Description Schema, MADS version 2.0. This is the first major revision of MADS since its initial release in 2005. MADS web site: http://www.loc.gov/standards/mads

Major changes in MADS 2.0 are:

• Elimination of dependence on the MODS schema
  
• Updated elements that are the same in MODS to reflect version 3 (e.g. added additional subelements under hierarchicalGeographic, added descriptionStandard under recordInfo)
  
• Addition of authority URI and value URI for controlled lists
  
• Addition of and elements
  
• Addition of an otherType attribute on for relationship types not enumerated in the schema
  
• Ability to specify if a subject heading can be subdivided geographically

A complete list of changes in MADS 2.0 may be found at http://www.loc.gov/standards/mads/changes-2-0.html. MADS user guidelines are under development and will be made available soon. Please direct any comments or questions on the MADS 2.0 Schema, or MODS/MADS developments in general, to the MODS Listserv http://listserv.loc.gov/listarch/mods.html.

MARC Update No. 12 is Ready for Local Print

In 2008, updates of both the full and concise MARC 21 Formats were made available online and the principle was established that the online is the version of record for the formats and the print a byproduct that is produced after the online version. Taking this into consideration, along with the decreasing demand for print, the Network Development and MARC Standards Office has decided to no longer print and sell updates to the full versions of the MARC 21 Bibliographic, Authority, Holdings, Classification, and Community Information Formats. Instead, NDMSO has developed a stylesheet that removes characteristics of an online page when it is printed -- such as breadcrumbs, extraneous links and text -- so that it resembles the print version formerly sold by CDS.

Users who want a print of changed fields will be able to print them from the Format web pages. Eventually all fields will be printable in this manner, but for now only Update 12 fields have been conditioned for improved printing. Changes to the MARC 21 Formats that resulted from Update No. 12 (October 2010) are displayed in red print. The online documentation will incorporate a print guide for an update as part of the "Format Changes" Appendix found in each format's table of contents page.

Please note that the MARC 21 Concise Format document will continue to be printed and it will consist of the Bibliographic, Authority, and Holdings formats. The 2011 edition will be available in the last quarter of 2011.
