And when I went to Uni it was heaven; I would take armfuls of books that weren't even related to my subject simply because they were there and interesting. I might initially do a search for something but once I'm there I'll browse the entire aisle.

I was always happy to do that, too. :) Especially since I worked in the library all but my freshman year, and so was always stumbling across interesting stuff. I still remember the first time I shelved on the literature floor and discovered that they had fiction beyond boring stuffy books by dead white dudes. (I usually worked in the classics, philosophy/religion, and history sections.) It was so dangerous to have it all right there, so close but with no time to read any of it.
