Answer 1

If you hear that a pilot has to work on "revisions", it's usually talking about either a Jeppesen subscription or company manuals.

Jeppesen is a company that publishes navigational material - mostly instrument approach information, but also enroute charts, departure information, international regulations and procedures, and so on.  These are usually custom to the areas and airports where an airline flies.  Revisions arrive every week or two, depending on the subscription.  The size of a revision could be as little as one page or as much as several hundred.

Company manuals are also changed from time to time and must be revised.

Revisions are a somewhat tedious process.  Not difficult, but time consuming.  It involves finding and replacing specific pages in a whole stack of books.
