EBooks are an additional factor undermining the income of writers. Many fiction paperbacks sold during the second half of the Twentieth Century were purchased, but not read in entirety. The actual percent of purchased, but never finished novels before the advent of the eBook are statistics writers should be aware of.
It is possible to read a great deal of an eBook without purchasing it. Free reads in the beginning, skips to other portions, and then later returns to read the rest either satisfies the curiosity of many potential buyers, or allows them to read for free. Some might argue a book is not that good if a reader does not finish the book, but many other factors dictate whether a reader has time to finish a book. Regardless, readers who purchase but never finish must account for a third of the paperback buyers.
