Step into a large bookstore with computers capable of finding the book you want (catalog thing, can't think of it's real name), and find the book from there. No human contact involved except for the cashier, who probably wouldn't care less either way...
Catalog. Though the specific bookstore might give it its own cute name. (A library might, too. For years my public library's computer catalog was called "Maggie.")
Or just go to the public library. Their catalog will almost certainly be better, and it'll be easier to find a specific item because the stacks are organized to that end. Bookstores want you to look at stuff that you didn't have in mind, and set things up to be distracting (and overstimulating for some) because this makes most people buy more stuff. Library workers are trained about respecting people's privacy and won't even look at what you check out, much less comment about it.
If you don't want to use their catalog at all, you can probably just charge right past it and go to the shelves -- 150's (psychology) 360's (social services) 370's (education) and 610's (applied sciences: medicine) or in R (medicine) H (social sciences) or L (education) if it's Library of Congress system. Most of the books about autism in the academic library I use are RC553.somethings. But you'll miss all the cross-referenced stuff if you just go to the subject-heading numbers and don't look at the catalog. You can usually get your local library's catalog online and do it at home, though, and then you just walk in with your note-pad of call-numbers and go straight to the stacks.
