There are three versions of the same lexicon - the "little Liddel" - pretty small, the "middle Liddel" - two or three inches thick, and the "Great Scott" - a foot tall and about 2300 pages (including the supplement).
After hansen and quinn, we usually go to basic texts with notes. Cambridge has a bunch (they're yellow and green - you can't miss them)
