Our collections are a unique and valuable resource for the state of Maryland. They include items collected by Marylanders in the disciplines of geology, mineralogy, entomology, malacology, herpetology, ornithology, mammalogy, paleontology, archaeology and botany. Some of them are scientifically significant and are studied by scientists. Others lack data or are duplicates and so are used in hands-on educational programs and art classes.
Though the Natural History Society of Maryland was founded in 1929, our collections represent centuries of preserving natural objects. The NHSM had its start from within the Maryland Academy of Sciences, and many of our older collections were transferred from the Academy to the new organization. Since that time the NHSM has built its collection in every discipline.
Arctos
Arctos is an online collection management system that helps museums, universities, and research centers organize and track their collections. It is free to the public, ensuring that important specimens and artifacts are preserved and their data is accessible to all audiences. NHSM is actively working to make its collections available via Arctos.
