Once you have your resources in TEI-compatible XML, you can do lots of different things with it ... including things you hadn't even thought of when you rescued this information! E.g.:

• make links between your collections management database and the primary sources of acquisition information
• populate a database (or a Topic Map) with data and assertions drawn from your TEI data
• publish your material as a set of facsimiles, with the TEI data offering support for searches (or as a ‘normal’ web site)
• break up past publications into ‘chunks’ (e.g. about one object, one person) and re-use these in future projects
