The Virtual Vietnam Archive contains over four million pages of scanned materials, including documents, photographs, slides, negatives, oral histories, artifacts, moving images, sound recordings, maps, and collection finding aids. The resource is part of the Vietnam Center and Archive at Texas Tech University. The focus of the material tends to be personal, rather than official in nature: eg. photographs, letters home and home movies. Non-copyrighted material which has been digitised is freely available for users to download. The audiovisual materials pages alone includes over 650 donated digitised films as well as material generated by the Vietnam Center and Archive itself: lectures, conference proceedings and interviews. The donated films include items from various collections, much of it originally filmed on 8mm or 16mm film. The films can be viewed in MP4 format or downloaded as MP4s or WMV files. To enable navigation of such a huge resource the archive has provided a Research help page, which includes subject guides, links to various search pages and focused browse pages eg. Browse the Digitized Audio and the Oral History page.
