The librarians at the City Colleges of Chicago maintain an excellent list of free, public databases. This list is regularly updated and is organized alphabetically (but can be searched by keyword by using Control-F on a standard computer). Here are some of the highlights:
Gutenberg-e: A digital book collection.
"Columbia University Press is pleased to announce that Gutenberg-e is now an open access site. These award winning monographs, coordinated with the American Historical Association, afford emerging scholars new possibilities for online publications, weaving traditional narrative with digitized primary sources, including maps, photographs, and oral histories."
Immigration to the United States, 1789-1930: A primary sources collection.
"Immigration to the United States, 1789-1930, is a web-based collection of historical materials from Harvard's libraries, archives, and museums that documents voluntary immigration to the United States from the signing of the Constitution to the onset of the Great Depression. Concentrating heavily on the 19th century, Immigration to the US includes over 400,000 pages from more than 2,200 books, pamphlets, and serials, over 9,600 pages from manuscript and archival collections, and more than 7,800 photographs. By incorporating diaries, biographies, and other writings capturing diverse experiences, the collected material provides a window into the lives of ordinary immigrants.
In addition to thousands of items that are now accessible to any Internet user, the collection includes contextual information on voluntary immigration and quantitative data. The site offers additional links to related digital resources on immigration to the US, including vital materials on the African diaspora."
OECD iLibrary: A collection of economic reports.
"The online library of the Organisation for Economic Cooperation and Development (OECD) featuring its books, papers and statistics and is the gateway to OECD’s analysis and data."
