This chapter is as close as the Tag Library gets to a user guide to tagging JATS documents using the Authoring Tag Set. It provides descriptions of common tagging practices and guidance for specific tagging issues. Essays discuss JATS structures and the design choices involved in tagging complex conceptual structures, for example, author affiliations and keywords, which involve numerous choices among elements and attributes. These essays are important for learning to use this Tag Set well.

Since there are as many different uses of this Tag Set as there are users, “Best Practice” is an elusive concept, impossible to define for all users. But in many situations there are common practices, and it is sometimes possible to explain several good practices, allowing an archive or publisher to determine if one practice fits their situation. This section contains tagging write-ups, more extensive than is appropriate for any single element page, that offer such tagging advice and alternatives.
