Guidelines
  • You can enter an ISBN either with or without hyphens.
  • Do NOT add punctuation at the end of the number.
  • You can enter either a 10-digit or 13-digit ISBN.
  • Information that qualifies the ISBN such as publisher, binding, format, volume number, etc. can be entered in parenthesis after the ISBN in subfield a.
  • If the ISBN shows only 9 digits, it may be an SBN. Under this earlier scheme, the first digit was not used. Type a zero before the other 9 digits.
