As part of ongoing efforts to facilitate data exchange between documentation centers dealing with the underground world and karst, the Namur Underground Heritage Library has recently placed its database under the ODbL license. This allows for automatic data exchange with other libraries using the same license, particularly with BBS data accessible on Grottocenter.
You now have access to explanations of all the features, as well as an FAQ listing the questions we receive. The menu has been expanded, and translations are underway. If you'd like to contribute to the translation process, it's very simple: create an account by editing the page corresponding to the language you speak.
