Searchable Adger, first half
I just happened to type something into Google and saw to my surprise that it pointed me to a PDF file containing a chapter of our textbook. This is probably (ok, well, certainly) not copyright-kosher, but perhaps it is useful. And it’s not after all my infringement, I’m only mentioning that you’ll find this if you look. (Besides, you will still need to own the textbook, because the later chapters are not available online, nor are the exercises at the end of the chapters included). What caught my attention was that, although these are scanned, they’ve also been run through a character recognition program, so you (and Google) can search them.
Try it, search for “Kiss Anson quickly” (p. 113) or “That bookcase is loud” (p. 89).
I’m not sure what use this really is to you, but I suppose if you remember reading something in there somewhere (in the first half of the book) but not where it was, you could now search for it rather than flip pages for 45 minutes.
