Category:CS1 errors: OCLC

This is a tracking category.
It is used to build and maintain a list or lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the encyclopedia's categorization scheme.
More information:
  • This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
  • These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience.
  • These categories also serve to aggregate members of several lists or subcategories into a larger, more efficient list (discriminated by classifications).
  • Typically, tracking categories are automatically populated by templates invoked in pages or by the MediaWiki software (see Special:TrackingCategories for an overview of the latter).


Administrators: Please do not delete this category even if it is empty!
This category may be empty occasionally or even most of the time.

This is a tracking category for CS1 citations that have |oclc= errors.

Help desk

Check |oclc= value

The |oclc= parameter is for the OCLC identifier. Only a single OCLC identifier is allowed. (If relevant, multiple OCLCs can be specified using |id={{OCLC|...}} instead.)

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 (or more) digits
  4. prefix (OCoLC) followed by a variable number of digits without leading zeros
  5. 1 to 10 (or more) digits without prefix

Further validation is not performed.

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

If the value is correct and larger than the currently configured limit of 12500000000, please report this at Help talk:Citation Style 1, so that the limit can be updated.

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

Pages with this error are automatically placed in Category:CS1 errors: OCLC.
