I am trying to determine the availability of electronic versions of a
number journal titles (300) as well as which databases provide access to
the full text of these journals. Any ideas on how to approach this would
be greatly appreciated. We are attempting to evaluate duplication in our
print and electronic journal collections and many of the latter we
receive through aggregators. Do we need to check each aggregator for
availability or is there a central index with information on location of
full text electronic journals in databases?

Thanks in advance. I truly appreciate your response, as I'm not quite
sure how to approach this.
