Category:Index pages of works originally in an unknown language

This category should be empty. If it is not, that indicates that the contents require maintenance.

This page has a backlog that requires the attention of one or more experienced users or administrators. (This template is added automatically when this category has members.)

Pages in this category have an unknown language in the index language field. Probably:

• the language in the field is invalid (usually this is because the language is not using a correct code: e.g. English should be en), or
• the language is not supported by Module:ISO 639 and should be added there.
