The IT History Society http://www.ithistory.org/ is an international group of over 700 members working together to document, preserve, catalog, and research the history of Information Technology (IT). One of their most useful things for students and teachers on their site is an International Database of Historical and Archival Sites, where you can look up and research everything from pre-Apple history to ZZT-oop (an early in-game scripting programming language). The databases are listed alphabetically, and can be sorted by institution or country.
The Social Networks and Archival Context (SNAC) is basically a social network of archives. It’s a bit like one-stop shopping: it exists to help historians and other researchers make connections among the people they are studying by mapping the ways in which they can be connected through archival materials.
From the blog post introducing SNAC to the public:
Let’s look at an example of Shirley Chisholm in SNAC. In just the National Archives Catalog, Chisholm has an authority record and is connected to just five descriptions. There are a pictures of her, an interview, and more… But the Archives is not the only repository to collect Chisholm’s work: 51 collections in SNAC either list her as the creator or have a referenced to her. For example, Chisholm’s letters are located in the New York Public Library.
Not only can you find a single person in multiple archives using SNAC, but you can also find records for people and organizations associated with them — so for Chisholm, some associated names are “major historical figures like Presidents Jimmy Carter and Lyndon Johnson; Shirley Bernard, a professor and an active member of the National Organization of Women; and Constance Baker Motley, an important African American judge and social reformer.” (The featured image is of the network of names associated with Chisholm’s, which also shows if the names were connected apart from their connection through Chisholm.)
This makes SNAC a tremendous tool not only for doing historical research, but for situating research in context.
