Search letters

With correspSearch you can search within the metadata of diverse scholarly editions of letters. One can search according to the letter's sender, adressee, as well as place and date of the letter's creation.

This web services assembles and analyzes files in the Correspondence Metadata Interchange (CMI) format which is based on the TEI extension "correspDesc" developed by the TEI Correspondence SIG.

The database is continually growing. Any published scholarly edition of letters (in print or digital form) can create an index according to the "Correspondence Metadata Interchange" format and register with the web service correspSearch.

correspSearch v2 online

The next generation of the correspSearch web service has gone online. It now offers greatly improved search and filtering options as well as its own map-based search, which can be used to search for letters from a specific area in a specific time period. The whole website is now responsive and can thus also be used on mobile devices. Finally, a lot has been done "under the hood": the entire harvesting and ingest process has been improved.

csLink – Link letters automatically across scholarly editions

The API allows you to query correspSearch automatically and integrate the results into your own website.

Query results are provided as TEI-XML files. See the documentation of the interface to learn about how to set up a query.
