Online Research Tools

In recent years, Jefferson Patterson Park & Museum has developed web pages designed to make archaeological data easily available to researchers and the public.  We currently have five different web sources available, ranging from artifact identification tools to artifact and paleobotanical databases.  A short description and links are provided below for each of these web resources.  Also included is a link to the Jefferson Patterson Park & Museum searchable library catalog and information on accessing archaeological collections curated at the Maryland Archaeological Conservation Lab.

Archaeological Collections in Maryland

This finding aid to more than 30 of the most important collections held at the Maryland Archaeological Conservation Laboratory includes a searchable database of the artifacts and field records from each of those collections.

The Diagnostic Artifacts in Maryland website, created by the MAC Lab in 2002, was designed as an introduction to artifact types commonly found at archaeological sites in Maryland.  This online resource, which uses the extensive MAC Lab collections to create accessible identification tools and resource materials, has proven invaluable for archaeologists, curators, students and anyone interested in Maryland and Mid-Atlantic history.

This unique resource aggregates Maryland’s paleobotanical data in a searchable format with interpretive summaries that place the information in a publicly-accessible and user-friendly format.   Project components include summaries of archaeological sites bearing plant data, a searchable database of archaeologically-recovered plant remains, and an interpretive history of Maryland’s landscapes.


Maryland Unearthed

Maryland Unearthed serves as a guide and provides access to many of the important archaeological collections maintained by the Maryland Archaeological Conservation Laboratory, the state's central curation facility.

This web site was produced under a generous grant from the Maryland State Highway Administration.

This website was created to assist in the identification of carbonized wood samples from archaeological sites.  In addition to descriptions of thirty-one hardwood and softwood species found in Maryland, the site contains high resolution photographs of the cellular structure of each species, both in carbonized and non-carbonized forms.


The JPPM Research Library holds one of the region’s largest reference collections on the archaeology and history of Maryland and the Middle Atlantic area. We have over 12,000 references dealing with such topics as Native American life, the identification and conservation of artifacts and antiques, agricultural history, historic buildings, museum studies, and archaeology around the world. Many of our books and journals are rare, and would be hard to find at other libraries.
