Category name[]
I think that the category name might be misleading, as it could be taken to mean "The page needs more references", rather than "the references on the page are missing information" - but I can't think of a better title.
Even "Pages with missing reference parameters" could be taken by a layman to mean "The page needs more references".
I was hoping that typing this would give me inspiration, but no luck yet.
"Pages with broken references" is fairly clear. However, the incomplete references aren't "broken" or "invalid", so those descriptors don't apply. They're just "Missing information", or "incomplete". The "Pages with broken references" category is also for immediate problems, whereas the incomplete references work, but need more info.
Just "Broken references" would also be clear, and "Incomplete references" would also not be clear.
There is an automatic category "Pages containing omitted template arguments", but that's not accurate for these incomplete references.
"References to update" could work, but is non-specific.
Maybe I'll think of something later. -452 (talk) 17:04, December 12, 2014 (UTC)
