Style Guide

USE "HathiTrust"
NOT "Hathi"
NOT "Hathi Trust"
NOT "the HathiTrust"
  • HathiTrust = the initiative, the enterprise, the partnership, we, the HathiTrust participating libraries
  • HathiTrust repository = the repository, the HathiTrust repository
  • HathiTrust Digital Library = Hathitrust repository and accompanying services
  • "HathiTrust" by itself (not followed by repository or digital library) is the preferred general reference.
