Over the weekend, I picked up a small stack of quality books from an estate sale for a mere $5; if I'd had $100, I could acquired about 500 books but several repair bills (central air conditioning, car, dryer, car again, laptop, dryer again, in that order ) claimed priority on my budget.
Among the books were these: The Story of English, which was a companion book to the PBS series; The Handbook of Good English, by Edward D. Johnson, and the sixth edition of Wheelock's Latin. All of them are pleasures to read with whatever level of commitment can be summoned. Latin, in particular, is something I feel drawn to but have never studied beyond the very basics (the word "ablative" freaks me out.) Maybe some day.
