Meeting MARC: the 50-year-old data format for library records

Some links used in the presentation:
Library of Congress's documentation for Bibliographic MARC, the kind being discussed here: www.loc.gov/ma...
Documentation for the 856 field: www.loc.gov/ma...
The most recent format change list: www.loc.gov/ma...
This link is to a different MARC record than the one used, it's from the Library of Congress, the link at least temporarily works. catalog.loc.go...
Text of many questions from the chat and when they were answered in the Q&A:
"I saw cau for calfornia. Which all places get a code? Is there some entity that assigns name codes?" answered: 20:58.
"I wonder if the people studying library science are usually expected to get famiiiar with MARC when they are still students? Or do they work with it only after they start working as librarians?" answered: 22:30
"I get the feeling the spec for this must be huge. Does it take very complex software to parse and process all this stuff?" answered: 24:30
"Right, I'm thinking of museums now. I wonder if museums have their own MARC-like thing to cataloge inter-museum stuff?" answered: 28:32
"Do libraries keep MARC records for journals for which the library has revokable subscriptions" answered: 32:44

"Any easter eggs or fun tricks in MARC?" answered: 44:23
"I heard of something called maybe WorldCat, some sort of free catalogue. Is this MARC or something else?" answered: 45:40
