The IT History Society (ITHS) is a world-wide group of over 500 members working together to assist in and promote the documentation, preservation, cataloging, and researching of Information Technology (IT) history. We offer a place where individuals, academicians, corporate archivists, curators of public institutions, and hobbyists alike can gather and share information and resources. This catalog of resource sites concerning IT history is the only one of its kind and is a valuable resource for IT historians and archivists alike.
