Karlsruher Virtuelle Katalog (KVK)
Meta-search engine for library catalogues from all over the world, collections of digitised material and online bookshops; includes the global library catalogue, WorldCat. For the most part it finds catalogue records only, but it also links to full-text material from the Hathi Trust, Google, the Directory of Open Access Journals and so on. Users can select which catalogues, digital resources and bookshops they wish to search, then search for books, serials or other material by key word, title, author, et cetera.
