==Major Dates in Recent Library Descriptive Metadata History==
The date of metadata creation affects what type of information is contained within a record as standards have evolved over time. By knowing the dates, at least you know where to go look up the rules for any metadata you happen to be struggling with.
===1961 International Conference on Cataloging Principles - "The Paris Principles"===
Established agreement on entry and choice of heading for bibliographic records. After this meeting there was increased uniformity among national cataloging practices because many countries rewrote their cataloging codes to conform to these principles. Principles were based on [http://en.wikipedia.org/wiki/Seymour_Lubetzky Seymour Lubetzky's] work, which was built upon [http://en.wikipedia.org/wiki/Anthony_Panizzi Panizzi] and [http://en.wikipedia.org/wiki/Charles_Ammi_Cutter Cutter]. There were inconsistencies and different interpretations in the application of the Principles despite agreement on common components of descriptive metadata. National libraries of different nations applied the rules differently.
===1967 Anglo-American Cataloging Rules (AACR) published===
British and U.S. versions somewhat distinct
===1971 First Draft of International Standard Book Description (ISBD)===
There was a need for a uniform standard of application of the Paris Principles. IFLA developed a draft standard, applied immediately by UK, France, and Germany. The standard went through years of refinement. Initially it was applied solely to monographs and morphed into the ISBD(M) ... M standing for monographs and ISBD(G) for general framework. The recognition of various types of library material led to the development of ISBD(S)for serials, (CM) cartographic materials, (NBM) non-book, (PM) printed music, (A) antiquarian, (CP) component parts (i.e. analytics for the contents of works). In 2011, the various ISBDs were consolidated into a single text. ISBD has a major affect on MARC data entry as ISBD punctuation is used in within the fields. ===1978 Anglo-American Cataloging Rules, 2nd edition (AACR2) ===Unified British and U.S versions, incorporated ISBD principles. In U.S. it meant a substantial change in the form of headings for corporate bodies. === 1988 Anglo-American Cataloging Rules, 2nd edition, 1988 revision (AACR2rev)=== === 2002 Anglo-American Cataloging Rules, 2nd edition, 2002 revision (AACR2rev2)=== === 2010 Resource Description and Access (RDA) published ===Began life as AACR3. Became RDA when change was determined to be so substantial as to merit a fully new text. The name change also reflected the desire to include non Library/Archive/Museum stakeholders in the process of creating the standard. ===2011 Consolidated edition f International Standard Book Description (ISBD)===The consolidated edition merges the texts of the seven specialized ISBDs (for books, maps, serials, sound recordings, computer files and other electronic resources, etc.) into a single text.
