EDTF Date – 046 – RDA Cataloging Examples
RDA Cataloging Examples of use of Extended Date Time Format (EDTF) in MARC 21 field 046 for Special Coded Dates in Resource Description and Access (RDA) Name Authority Records
When supplying dates in field 046, use the Extended Date Time Format (EDTF) schema in all cases except for centuries; supply dates using the pattern yyyy, yyyy-mm, or yyyy-mm-dd; always add subfield $2 edtf except after a century. The more consistent use of $2 edtf is based on a PCCLIST discussion suggestion to simplify the use of $2 (always use except for centuries). Visit above RDA Blog link to read complete article.
IMAGINE if libraries could represent themselves together in a way the Web could see and understand.
The objective of The Libhub Initiative is to publish BIBFRAME resources to the Web, cross-link resources which are common among libraries, and, through cross-linking improve the ability for people to discover these resources on the open Web. The goal is ultimately that users would then be able to click on appropriate resources and be taken back to the library’s catalog.
