Indeed, I believe the name "Katub-zahar" very nearly means "library". We know from the Dwarvish name of Nogrod, Tumunzahar (or "Hollowbold"), that "zahar" means "bold" or "building". Thus, "Katub-zahar" would appear to mean literally "Book-building" or more figuratively, "library".
Just curious, where did you get the translation of zahar from? The only site I can find that mentions the meaning of Tmunzahar gives it as
tûm “bold / delving” (1st decl., type B) (in Tumunzahar, q.v.)
*zahar “hollow” (adj.) (in Tumunzahar, q.v.)
This of course would mean that Katub-zahar means Book-hollow or Hollow-book instead (or even Hollow of the book).
