G'day Okiemockbird,From behind a pile about 2 feet high of Dover books (mostly illustration, but including an affordable Cecil Sharp and various 19th century music books) I have to say I am sad to hear of Hayward Cirker's passing. I could only look in amazement at the number of previously unobtainable books that Dover put out ... at about 1 book a day! (And they would accept suggestions for anything suitable.)
Back in the halcyon days we, in Australia, could buy their books at American cover price ... now about 2x.
