This is a previous version of the article *Chord diagrams, contact-topological quantum field theory, and contact categories*. It contains less content, in particular about contact categories, but is less terse (or more prolix!) and contains more background. It might be useful for some readers, and so I retain it here, even though it has been superseded by that article.
