NOTE - your R number, your eRaider, your email address, and your library barcode are 4 unique identifiers needed frequently during your association with TTUHSC. It is recommended to commit them all to memory.

  • An 'R' number is a unique identifier 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 upon request only. You must create a library account before you can:
    • Borrow any physical items such as books, anatomical models, laptops and DVD/CD's
    • Use any non-free library services such as interlibrary loan, electronic document delivery, or 3D printing

NOTE - the TTUHSC library may or may not also use your R number as your library account barcode number.
