This is a bit random, but do publishers like Penguin move a lot of classics each year? Middlemarch’s rank in the Amazon USA list would seem to indicate it sells around ten copies a day. Does that seem reasonable? I thought it seemed a bit low, but my opinion is truly random. There are >12 different paperback editions, so that would seem to argue for popularity…
I think classics, like Middlemarch, remain hot sellers, especially with the variety of paperback editions available. Based on Middlemarch’s rank on the Amazon USA list, selling around ten copies a day seems reasonable. However, opinions on what constitutes reasonable sales can vary.
