Category:Citation Missing

The pages in this category have a missing citation. This means one (or more) of the Template:Ludography cite or Template:Ludography ref are attempting to reference a book or periodical. Unfortunately this title does not exist in the underlying books tables. To fix this check the following:

1. The spelling of the name used in the template does not match the spelling in the source article. In this case a simple update of the name= parameter should fix the issue.
2. The title being referenced does not use the Template:InfoboxBook2. Update or add the template as needed.
3. The title isn't in our Ludography. Please add the article with the correct information.
