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 It might be useful for some readers, and so I retain it here, even though it has been superseded by that article.

Chord diagrams, topological quantum field theory, and the sutured Floer homology of solid tori
