These pages are deficient, that is, they may be erroneous or otherwise seriously defective, and require urgent revision.
They may also represent a topic which has not yet been covered by an EoM page ("wanted page").
In that case it is helpful that the page text at least gives a list of links to EoM pages which do mention that topic.
Existing, but deficient pages should be urgently converted into TeX (put in Category:TeX wanted), in order to ease revision (unless their text is deemed to require a total revision).
