After the class, I actually understood these readings. MARC makes much more sense to me now. It will be much better when I start creating these MARC records.
A MARC record is a MA chine-Readable Cataloging record.
“Machine-readable” means that one particular type of machine, a computer, can read and interpret the data in the cataloging record.
Cataloging record: “Cataloging record” means a bibliographic record, or the information traditionally shown on a catalog card.

1.Fields are marked by TAGS.!
A field: Each bibliographic record is divided logically into fields. There is a field for the author, a field for title information, and so on.
A tag: Each field is associated with a 3-digit number called a “tag.” A tag identifies the field — the kind of data — that follows.
example:
100 1# $a Pirsig, Robert M.
2. Some fields are further defined by INDICATORS.
Indicators: Two character positions follow each tag (with the exception of Fields 001 through 009).
Each indicator value is a number from 0 to 9. (Although the rules say it can be a letter, letters are uncommon.)

authority control is very important: library of congress authorities website to check for subject headings.
