  • HTRC Data Protection Level Mapping
Skip to end of metadata
Go to start of metadata

HTRC maintains rights information for volumes available via the HTRC Data API. This information is generating by mapping the HathiTrust Rights Attributes and Access Profile onto an HTRC Data Protection Level (Table 3). A text file containing the HTRC Data Protection Level for each volume is returned in an HTRC Data API call.

  • Rights attribute: the copyright or access category to which the volume belongs (Table 1).
  • Access profile: a value that is derived from the source of the volume, and summarizes the rights-related behavior of the source (Table 2).

The rights information stored for every volume in the HathiTrust library is described below. For more information about HathiTrust Rights Attributes and Access Profiles, please see: https://www.hathitrust.org/rights_database
