In addition to Web of Science (including Conference Proceedings), major ISI WoK databases (Biosis Previews, Current Contents, Zoological Record) are now cross-searchable on vLib – example (MPG on-campus only) – which may be considered to be used as an alternative to the WoK All Databases search.

The metadata quality of the All Databases data source does not seem to match the quality of data as retrieved from single databases, which involves all sorts of disadvantages, e.g. problems with full text linking (wrong metadata is sent to the link resolver which is thus unable to provide a correct full text link).

Please note that cross search in general may or may not deliver results as desired. Please see vLib search tips for more information.
