A collection of some simple Javascript prototype tools I have created during my mandatory Swiss civil service in order to facilitate the addition of coordinates to the bibliographic metadata of the Ryhiner Map Collection at the University Library Berne.
Some documentaion can be found at doc/RyhinerBoundingBoxToolDoku.pdf (unfortunately, German only).
You can try the tool here.
