The basic archival practices for arrangement and description of architectural records evolved prior to the electronic era. Now as more is being learned about digital documentation of architecture, the underlying principles of arrangement and description continue to be validated even as archival practices evolve. In archival arrangement the principles of provenance or respect des fonds and original order are now being understood as a way to capture and retain information on the source and organization of groups of documents. In archival description, computer-based information tools have become widely adopted and the power of the internet and the world wide web are improving delivery of information. As technological solutions continue to evolve, the underlying principles and goals of archival arrangement and description will remain unchanged even as they continue to be adapted to the changing information environment.
