Category:CS1 errors: bibcode

This is a tracking category. It is used to build and maintain 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 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 sub-categories into a larger, more efficient list (discriminated by classifications).

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 |bibcode= errors.

length must be 19 characters (<message> = 'length')

characters in position(s): (except as specified otherwise, violations produce 'value' in the <message> portion of the error message):

1–4 must be digits and must represent a year in the range of 1000 – next year (<message> = 'year')

5 must be a letter

6–8 must be a letter, ampersand, or dot (ampersand cannot directly precede a dot; &. (<message> = 'journal'))

9 must be a letter or dot

10–18 must be a letter, digit, or dot

19 must be a letter or dot

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