The Montana Antiquities Database contains cultural resource information on known historic and archaeological sites, previously conducted cultural resource inventories, National Register site status, and cultural resource management project information. The database is updated and maintained by the Montana State Historic Preservation Office in Helena.

The database is divided into three parts:

Cultural Resource Information System (CRIS)
The CRIS portion of the database contains information on over 51,000 historic and archaeological sites within the State of Montana. It includes information on site type, owner, period, legal location, and numerous other data fields.  The SHPO requires Smithsonian numbers in order to process all consultation, including resolving APE, Eligibility, Effect etc., as it is the sole means of tracking properties.  To obtain a Smithsonian number see below.
Cultural Resource Annotated Bibliography System (CRABS)
The CRABS bibliographic listings contain information on over 30,000 previous cultural resource inventories conducted within the State of Montana. It includes information on author, title, date completed, survey acres, legal location, agency, and other useful data fields. It also includes a list of searchable keywords that allows us to generate reports on specific topics.

Project, Eligibility, & Effect Report (PEER)
PEER includes information on cultural resource projects conducted around Montana, and that SHPO reviews on a regular basis. It includes information on the eligibility of sites, effects, and more general project information.
