These best practices are for libraries using the Text Encoding Initiative’s Guidelines for Text Encoding and Interchange (P5). They are intended for use in large, library-based digitization projects, but may be useful in other scenarios as well.
There are many different library text digitization projects, for different purposes. With this in mind, these best practices are meant to be as inclusive as possible by specifying a series of encoding levels. These levels are meant to allow for a range of practice, from wholly automated text creation and encoding, to encoding that requires expert content knowledge, analysis, and editing. The encoding levels are not strictly cumulative: while higher levels tend to build upon lower levels by including more elements, higher levels are not supersets because some elements used at lower levels are not used at all at higher levels.
