Open Source Lazarus HTML/XHTML Software

VideLibri lists the books you have borrowed from a public library and lets you search the library catalog from your local device. It has all the usual features of a library OPAC, i.e. viewing, renewing, searching and ordering books. It also renews all due books automatically and can do other things only a locally running app can do, like keeping a history of all ever borrowed books across multiple libraries. Developed in 2006, it is the world's first library app, and by supporting 20 different kinds of OPACs from different vendors, it is compatible with more libraries than any other app. So far VideLibri has been tested with 200 libraries in Germany/Austria/Switzerland successfully, but it was designed to allow any user to add their own library without requiring any/much programming knowledge. For this any URL of any webpage can be entered in VideLibri together with an arbitrary query. The spin-off cli-tool Xidel can run these queries on any non-library webpage.
