Best place on campus to gather textbooks (any subject, preferably over 100 pages)

As title pretty well much says, I need a place where there are textbooks, I don’t need them forever just a day or two and needs to be over 100 pages. Basically was on campus and taking my two basset hounds and my British shorthair cat on a walk, was going to the restroom real quick so I tied them just outside the restroom door to a traffic cone but upon coming back they were running across a field pretty well much like a cheeta with the cone attached to their leash. Realized I saw screwed and pretty well much now know I need some textbooks, basically I nicknamed my pets education pets (just a fun name don’t look at it all weird) because they love textbooks just really anything as long as it’s more than 100 pages. I just bang on them and they pretty well much come running. I have a semi truck so I can store quite a few but I’ll do some laps around campus once I get the books in my cab to try and attract them, but I need to get some textbooks first. So Q is, where to get these damn textbooks?
