NSDL has streamlined collection browsing at NSDL.org to make it easier to find what you’re looking for. Browse collections alphabetically or through subject gateways that include: Biological and Health Sciences; Engineering, Computing, and Technology; General Science and STEM; Geosciences; Mathematics; Physical Sciences; and Social Sciences. Within each of these broad categories, users may browse by audience: collections whose items have classroom utility are found in the For Educators and Learners category; collections without classroom application are found in the For Researchers and Professionals audience grouping. New Collections also displays collections according to date of accessioning, so newest collections are listed first.

NSDL’s flagship Pathways collections that are affiliated with specific disciplines or audience groups appear in a bold font in the collections browse feature. Selecting a specific collection name brings up search results for that entire collection. Pathways-related resources are also featured on the right hand side of NSDL.org search results as “Relevant Results form NSDL Pathway Partners”.
