Category:Category series navigation isolated

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:
 * 1) tracking only: the surrounding category structure is inherently sparse, or
 * 2) maintenance: Category series navigation was prematurely or incorrectly added.

To skip navigational gaps up to years, use yes.

For gaps larger than years, use  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.
