Classify from OCLC

Classify is a service from OCLC. Search, the resulting FRBR set is checked and then the classification numbers used displayed. Quick, simple way to get a class number. No need to be an OCLC member. Does Dewey, NLM, and LCC at least. Not sure about other less used classification schemes, like the one at the US Geological Survey.
