Within this project the spatial and visual characteristics of circular enclosures of the early 5th millennium BC in Germany are being investigated. The here presented ever-expanding repository comprises a database of all circular enclosures under investigation. The database entries include the coordinates and a thorough description of each enclosure. Additionally, several resources like skyline and viewshed maps, files of input parameters and plots of astronomical features are deposited.
You will find in the Access to Archival Databases (AAD) resource online access to records in a small selection of historic databases preserved permanently in NARA. Out of the nearly 200,000 data files in its holdings, NARA has selected approximately 475 of them for public searching through AAD. We selected these data because the records identify specific persons, geographic areas, organizations, and dates. The records cover a wide variety of civilian and military functions and have many genealogical, social, political, and economic research uses. AAD provides: Access to over 85 million historic electronic records created by more than 30 agencies of the U.S. federal government and from collections of donated historical materials. Both free-text and fielded searching options. The ability to retrieve, print, and download records with the specific information that you seek. Information to help you find and understand the records.
