The Wikipedia editor has marched right in and thrown out half of the extra ‘Killing time’ entries I added this afternoon to the ‘Killing time’ disambiguation page as if they did not exist, or did not matter. The rule of disambiguation is likely to be that only those entries shall remain that link to an already existing Wikipedia entry.

Is it really a service to Wikipedia users to spare them the awareness of other books of that title for which no one has yet cared to create an entry?

An entry without a link may spur users to create one. Deletion just serves to maintain the threshold where things only exist when they are in Wikipedia. I do not believe the editor went to the trouble of checking whether the books by, say, David R Dow, Sandy Fawkes, Noel Fellowes or Wade Hemsworth are worthy of coverage in Wikipedia. I am curious if adding an entry with a link yet without target would meet an editor’s inclusion criteria.
