Wikipedia will be unavailable on Wednesday, January 18th in protest of the SOPA and PIPA bills. More information is available here.
However, the library’s resources will of course still be available. If you need concise information about a particular subject quickly, Credo Reference would be an excellent place to start. Or you could begin your search using the new Ebsco Discovery Service, and the GALILEO subject list of databases offers even more options to help you find the information you need. If you have any questions or need any help, please contact a librarian.
