Check |oclc= value

The |oclc= parameter is the OCLC identifier. Only a single OCLC identifier is allowed. The identifier must be in one of these forms:

  1. prefix ocm followed by 8 digits
  2. prefix ocn followed by 9 digits
  3. prefix on followed by 10 digits
  4. prefix (OCoLC) followed by a variable number of digits without leading zeros
  5. 1 to 10 digits without prefix

Further validation is not performed.

To resolve this error, ensure that the |oclc= value is correct.

A tip for fixing this error: Editors sometimes place valid ISBN, LCCN, ASIN, or other identifiers in |oclc=.
