There are many decision that need to be made when transferring information from paper records to online records. In this case, we are moving the information to MARC records that are readable in library catalogs.
- What does the paper record respresent? Moravian music cataloged during the NEH cataloging project in the 1970s have compact descriptions. That is, all the manifestations of an entity are represented in one descriptive record.
For example, Christian Ignatius Latrobe’s cantata The Dawn of Glory has three manifestations: one printed organ-vocal score, one manuscript organ-vocal score and 16 manuscript parts. See the description here: Dawn of Glory.
A conceptual decision was made for these instances that the printed music have spearate records from the manuscript music. In this case, there was a record for Latrobe’s printed vocal score, plus a record for the manuscript vocal score with manuscript parts.
2. How does the catalog handle multi-part works (like a cantata), so that a single movement can be discovered? The catalogers made separate records for each movement of a work and included a musical incipit, so that the specific passage can be identified. These records were linked together by call number. In the online catalog records are linked together with linking fields.
In the case of the Latrobe cantatas, using the manuscript vocal score and parts as an example, there is a parent record for the whole cantata plus 16 records for individual movements. I call them the children records. So there is a parent record, plus 16 child records for the vocal score and parts.
