Credo Reference is an incredible database that we now subscribe to at the library. The database is a compilation of nearly 400 reference titles into one searchable source, with over 3 million entries! So many subjects are covered; this is a great place to find answers to general questions and for deeper research.
A unique feature of Credo Reference is the gadgets. You can use them to search within different contexts including people and places; convert weights and measures and there is even a gadget for answering crosswords! (No Cheating!)
