How might I go about exploiting Z39.50 to extract specific MARC
records from a library catalog?
More precisely, I am trying to download sets of MARC records from
remote library catalogs destined for a sort of union catalog. I see
each of these records being identified with a specific string in a
local note or local subject field. This string might be "CRRA", and my
question is three-fold:
1. What MARC field/subfield might I put this string?
2. How would I go about getting the string indexed?
3. How might I go about querying the server for records with this
string?
For example, I might put CRRA in 599 $a. I would cross my fingers
hoping this field gets indexes, and I might be able to search for it
like this [1]:
@attr 1=63 2=3 3=3 4=2 5=100 6=1 CRRA
Am I on the right track?
