DCM Z1:  372  Field of Activity

General:

When recording a term indicating the field, prefer controlled vocabulary, such as LCSH or MeSH, recording the source in subfield $2.  For consistency, capitalize the first term in each subfield $a.

Repeatability:

In choosing between repeating a field vs. repeating a subfield:  If the only addition to an existing field is an additional term from the same vocabulary, repeat the affected subfield.  If the vocabulary source differs, or if another associated element differs (such as a range of dates), repeat the field.  Overall best practice:  repeat the field when needed for clarity.

Example:

372  ##  $a Poetry $2 lcsh

372  ##  $a Craft brewing

[372 fields with a term from LCSH and a non-controlled vocabulary term.]
