"When Emily Dickinson's poems were published in the 1890s, they were a best-seller; the first book of her poems went through eleven editions of a print run of about 400. So the first print run out of Boston for a first book of poems was 400 for a country that had fifty million people in it. Now a first print run for a first book is maybe 2,000? So that's a five-time increase in the expectation of readership. Probably the audience is almost exactly the same size as it was in 1900, if you just took that one example."
