A nice general guide on how to approach historical research. It was written for undergrad students, so the information is a little thin sometimes, but it is a quick read and covers the important issues. As a graduate student I found the book sort of a rehash of other text books. It does have a lot of great lists of databases to search. I would assume that in the future this information will need to be updated as anything regarding the internet will have rapidly changed, been added to or disappeared.
