TrueSerials resource comparison tool

Tracy L. Thompson-Przylucki, Executive Director of NELLCO, just tweeted about a cool online resource from TrueSerials called the Resource Comparison.  It lets you compare the content of  up to 4 databases, choosing from a dropdown menu.  For example, you can compare the content of HeinOnline, Legal Trac, and LexisNexis Academic.  Once you choose the databases you want to compare you will get a table showing all the duplicate content in the databases, the content scope and currency.  You can also limit the search to full-text availability.
