Category:Infobox journals with missing ISO 4 abbreviations

This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories (except for eponymous maintenance categories).

This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme.

• This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set.
• These categories can be 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 as empty!

This category may be empty occasionally or even most of the time.

This is a maintenance category to identify articles with an {{Infobox journal}} that is missing its |abbreviation= parameter. Use the link given in the infobox to determine what the ISO 4 abbreviation of the journal is. One you determine what the ISO 4 abbreviation of a journal is (e.g. J. Foo.), put |abbreviation=J. Foo. in the infobox journal template.

|abbreviation= should contain dotted, title cased versions of the abbreviations (e.g. J. Phys., not J Phys or J. phys.). Additional guidance is available at Category:Articles with missing ISO 4 abbreviation redirects.
