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.

This maintenance/tracking category contains pages where {{Category series navigation}} was unable to link to any categories displayed in the year navigation box, and is thus navigationally isolated. This could either be for:
To skip navigational gaps up to 50 years, use |skip-gaps=yes
.
For gaps larger than 50 years, use {{Category pair|preceding category|succeeding category}}
on both sides of the gap, in addition to {{Category series navigation}}. Even if {{Category series navigation}} is isolated, it has the benefit of confirming the absence of nearby categories to the reader/maintainer.
To remove a page from this category, fill in the surrounding category structure, if appropriate. Do not create empty surrounding categories for the sole purpose of removing this tracking category.
Pages in this category should only be added by Module:Category series navigation.
