ROSA P is the National Transportation Library's Repository and Open Science Access Portal. The name ROSA P was chosen to honor the role public transportation played in the civil rights movement, along with one of the important figures, Rosa Parks.

Founded as an all-digital library program, NTL’s collections in ROSA P are full-text digital publications, datasets, and other resources. Legacy print materials that have been digitized are collected if they have historic, technical, or national significance. The repository is also designated as the full-text repository for USDOT-funded research under the USDOT Public Access Plan. Collections in ROSA P are available without restriction to transportation researchers, statistical organizations, the media, and the general public.

Collection Overview
To meet the requirements outlined in its legislative mandate, NTL collects resources across all modes of transportation and related disciplines, with specific focus on information produced by USDOT, state DOTs, and other transportation organizations. Content types found in ROSA P include textual works, datasets, still image works, moving image works, other multimedia, and maps. These resources have value to federal, state, and local transportation decision makers, transportation analysts, and researchers.

All resources in ROSA P are in the public domain and/or explicit permission has been provided by the rights holder to NTL to make their materials available for free over the web.

Persistence Statement
USDOT publications and data products deposited into ROSA P will be assigned a digital object identifier, or DOI, as a persistent identifier. This globally unique link will always lead users to a landing page containing the resource and its metadata or a description documenting the alteration and/or destruction of the information source, if applicable. The DOI will always resolve to a landing page with metadata describing the curation of the resource, even if the resource itself is removed. NTL’s plan for organizational persistence and succession can be located in its Digital Curation Policy
