I'm not sure if this site has digitised medieval manuscripts there or if it functions as a search engine for the rest of the web, but either way it's a good place to find medieval primary sources.
An excellent collection for research into the medieval period. Contains extensive descriptions of the manuscripts along with detailed accompanying information and is easily searchable. An enormous and diverse collection. Gotta love those Benedictines in Minnesota.
Not sure if I've already bookmarked another page from this site. It's a repository of European heritage, which for us means sources and images. I think it will become quite a massive repository of sources for all periods and regions of Europe.
These are a comprehensive set of pretty-good-quality maps covering just about every decade in Europe since the early C16th. They have some accompanying information which seems reliable enough.
This will only excite other Latinists out there. A very extensive collection of Latin sources from most regions in Europe. Bibliotheca Augustana multa bona magistris Latinae est!
A presentation of 68 motion pictures recording images of that American adventure in old-style colonialism, the Spanish-American War. Filmed in the US, Cuba and the Philippines.
Not sure how much you can access here. It at least has some manuscripts that you can access images of; looks like the rest of it might be in the process of being digitised.
A MASSIVE number of links to sites with images related to all areas and periods of history. You might need a spare week or two to go through all of them though. Gee, the internet's big!
This is a series of links focussing on images of architecture from a wide variety of regions and time periods maintained by Professor Jeffery Howe (Jeff to his mates) at Boston College.
