To enable extended metasearches, and thus to emphasize the big asset of metasearching (which is covering the widest possible range of information sources in the course of carrying out a single search) the number of resources searchable simultaneously via vLib has been increased significantly.
This enables creating overall search interfaces such as, for example, a search across all MPG Library Catalogs available at
which may be useful to locate a needle in a haystack.
Of course, users will be deciding whether the usability of huge metasearch interfaces is acceptable. Hence we are curious to have some feedback.
