  • An 'R' number is a unique ID issued by the TTU System rather than using your Social Security Number.
  • An eRaider account (username + password) is issued by TTUHSC Information Technology to login to most TTUHSC resources, including online library resources.
  • A library account is issued by the TTUHSC libraries on an as-needed basis. It is used to track borrowed items such as books, and to track financial transactions for non-free library services such as ILL (interlibrary loan), Document Delivery and 3D printing.
