How does a person go about exporting MARC records from a III system?
As you may or may not know, I spend a lot of my time developing a thing colloquially called the "Catholic Portal". It uses VUFind under the hood, and it requires me to ingest bibliographic data from a myriad of libraries.
Suppose the records I desire have the letters "crra" saved in MARC field 590$a. What is the process for connecting a III system, searching for "crra" in 590$a, and saving the result as a file of MARC records? Is there some sort of documentation I can read that will help me out in this regard?
