TG EMTAGS Code

(a limit field)

198 in tg

tg=198

The TG field contains the codes of the general concepts used to index the record. The text that correspond to the codes are displayed in the Translation of EMTAGS (EM) field. EMTAGS were discontinued as of 1998. For records after 1998, use the Subjects (SU) field to search.

Below is a list of EMTAGS and codes.
