"Databases are a large collection of data organized especially for rapid search and retrieval (as by a computer)." Thanks, Merriam-Webster Dictionary. In other words they are like huge online file cabinets full of credible, useful, reliable, and up-to-date information. Some databases contain articles from periodicals (magazines and newspapers). Some are reference databases. These databases have overview articles from encyclopedias to give you general information about a subject as well as lots of other great information. Databases are the tools of academic research.
We love databases because they are credible, trustworthy, reliable, and are easy to cite!
P. S. Hey Rams, our MICDS databases have a specific username and password. Ask your Librarian if you can't remember them.
