The Credo Reference database has a good selection of online dictionaries. You'll find general English language dictionaries as well as many subject dictionaries there. Here's a link to the Credo dictionaries.
We also have the Oxford English Dictionary online. It is the most comprehensive English-language dictionary and it's especially good for finding the history of individual words.
