Been buying 2ndhand books for 40+years,2ndhand records ditto, will look nearly anywhere, like doing serendipity in libraries(reference section) a,d among my own volumes, collect quotes and quotation books, the former into my own self-indexing notebooks. My lady-friend cut out a quotation about Shakespeare's Autolycos, where he's described as a "snapper-up of unconsidered trifles". That's what she thought I was doing, the trifles bit being her considered opinion. I offer Offer trifles, so it looked (w)right.
