For those Living Historians who reside in New Mexico, I have just completed assisting the Chama, NM library in developing a web presence. As part of their site, there are a number of historic sites and specialized databases that will help your research. To access the New Mexico El Portal you need to have a NM library card from your local library. http://chamalibrary.blogspot.com/p/resourcesyouth.html
However, you can access the first link of the page, NM history and historical photos without a password.
Collections from the Palace of the Governors Photo Archives
The Palace of the Governors Photo Archives contains an estimated 1,000,000 items including historic photographic prints, cased photographs, glass plate negatives, film negatives, stereographs, photo postcards, panoramas, color transparencies, and lantern slides. This important collection includes material of regional and national significance, dating from approximately 1850 to the present, covering subject matter that focuses on the history and people of New Mexico and the expansion of the West; anthropology, archaeology, and ethnology of Hispanic and Native American cultures; and smaller collections documenting Europe, Latin America, the Far East, Oceana, and the Middle East.
