It's completing the sets. You actually only need your starter zones 1-5, cold harbour, dungeon books and the rare ones in Cyro to top out. But you must complete the sets as there's bonus XP.

So you still have the 15th zone and Coldharbor left?
I am currently leveling a character and am almost to L8 in the Mages Guild and I have only collected books in 5 or 6 zones. So, while you have may have completed the collections you may still have missed some books as not all books in a zone are part of that zones collection. I have completed collections with a few books left unfound.
Are you on PC, do you have an Addon called Lore Books that shows you were the Lore Books are?
Are you doing the Mages Guild daily quest's?
These provide 10 Mage Guild rep points per turn in, so if your having trouble getting to level 10 via books this might be a way to get there. These quest's can be found in the Mages Guild in your alliances capital city, and send you out to retrieve a 'relic' in one of the public dungeons - you do not have to have done any of the Mages Guild quest line to do these dailies.
Just done my mages guild to 10... took me 200-210 books, with as many set completions as I could easily get using the lore book guides online.
