PsycBooks has grown to be a collection of over 1600 full text books selected by the American Psychological Association. The great thing about this database is that the book texts are searchable, downloadable, and printable, day or night. I often recommend looking here when you are just getting started with a psychology topic that is somewhat broad to get basic information.
In browsing around the Coverage List, I noticed how many early classics are available, some all the way back to the 16th century. There are also titles as recent as 2008.
