Based on requests from customers, we have begun work on adding 34X fields to records as part of our RDA enrichment options. For now, we are mainly concentrating on 344, 345, 346, and 347 fields. We are primarily looking for the data to populate/generate these 34X fields from the 300 field and 538 field. The 500 field is a catch-all field and has been used for almost everything over the years, which means it can be useful but also means that it may not be as reliable as desired in every case. We are currently debating whether it makes sense to also include 500 fields when adding information to the 34X fields. Karen Anderson put forth the research to develop our GMD to CMC rules (of which, there are over 1000 rules at this point). We are finding, however, that the 34X fields do not fit as neatly as desired in our general mapping workflows, so these are proving to be a bit more problematic to add. Still, we aim to have these in place in the next two months for libraries that may be interested in adding more descriptive fields to their records as part of the RDA enrichment options we have available. 344 - Sound Characteristics (link<http://www.loc.gov/marc/bibliographic/bd344.html>) - $a Type of recording - $b Recording medium - $c Playing speed - $d Groove characteristic - $e Recording track configuration - $f Tape configuration - $g Configuration of playback channels - $h Special playback characteristics 345 - Projection Characteristics of Moving Image (link<http://www.loc.gov/marc/bibliographic/bd345.html>) - $a Presentation format - $b Projection speed 346 - Video Characteristics (link<http://www.loc.gov/marc/bibliographic/bd346.html>) - $a Video format - $b Broadcast standard 347 - Digital File Characteristics (link<http://www.loc.gov/marc/bibliographic/bd347.html>) - $a File type - $b Encoding format - $c File size - $d Resolution - $e Regional encoding - $f Encoding bitrate [cid:image002.gif@01CFA4F1.06D6D590] Nate Cothran | Vice President, Automation Services Backstage Library Works | Provo, Utah & Bethlehem, Pennsylvania 801.342.5697 | nate@bslw.com<mailto:nate@bslw.com?subject=Automation%20Services%20-%20Inquiry> | bslw.com<http://www.bslw.com/> | ac.bslw.com/mars<http://ac.bslw.com/mars>
