My used book from Amazon just now arrived. It contains a first for me. Turns out that the used book seller is a law firm, Porzio Bromberg & Newman P.C. Attorneys at Law.
I’ve gotten books from people with one or two books to sell; I’ve gotten books from people running a business selling books; but never have I gotten a book from a business not in the business of selling books. Considering how much attorneys charge per hour, I feel my used copy of Legal Research is already worth more than the $40 I paid for it based on the time that somebody from a law office took to pack and ship alone!
