ISSNs can be automatically extracted from PDFs with a text layer by the "Library Codes" plugin and added as a Calibre Identifier.

The ISSN can also be used to find a Library of Congress Code and/or Dewey Decimal Code.

Added: the English Noun Frequency plugin is designed to give you sufficient information to figure out "at a glance" what a particular ebook is about. It will optionally update Tags and Tag-like custom columns with the N most frequent nouns, which can tell you a lot about a non-fiction book.

Added: Multi-Column Search (MCS) is used by Fan Fiction users to do full-text searches using regular expressions against .TXT formats of their ebooks, and then to apply other regular expressions to the previously found pieces of text to then update a custom column. This could be done to update a magazine's metadata if you had something regular to search for (e.g. ISBN or Issue Number) in a PDF that is first converted to plain TXT so it can be searched.
