A note about open access collections
You can find resources freely available on the web, but you'll want to choose reliable sites. Before relying on the information provided by a website, examine and understand the purpose of the website. While the purpose might not affect the accuracy of the primary source material it contains, it might indicate that the material has been altered or manipulated in some way to change or influence its meaning. Sometimes sites use primary source material to persuade the reader to a particular point of view, distorting the contents in obvious or subtle ways. Also, sites can use primary source material haphazardly, without appropriately choosing, inspecting, or citing the work. In general, look for websites with a non-biased, balanced approach to presenting sources. Websites produced by educational or governmental institution usually are more reliable than personal websites.
This is a dynamic and incomplete list. While these might be good starting place, depending on your research, there are many more institutions and collections, and no list could capture them all. Many more collections exist in a country's home language. Please contact a librarian for assistance.
