Credo Reference is a collection of online subject dictionaries and encyclopedias from trusted publishers. Since you know the name already, you can use the A to Z List of Databases to find it. You'll see it listed under the tab for C.
I'll include a link to Credo's video tutorials in case you want to become a supersearcher.
