Though you still have to deal with due dates, hold lists and occasionally clumsy software, libraries, at least for now, have one killer feature that the others don't: e-books you actually want to read.
To compare, I dug up best-seller lists, as well as best-of lists compiled by authors and critics. Then I searched for those e-books in Kindle Unlimited, Oyster and Scribd alongside my local San Francisco Public Library. To rule out big-city bias, I also checked the much smaller library where I grew up in Richland County, S.C.
Of the Journal's 20 most recent best-selling e-books in fiction and nonfiction, Amazon's Kindle Unlimited has none—no "Fifty Shades of Grey," no "The Fault in Our Stars." Scribd and Oyster each have a paltry three. But the San Francisco library has 15, and my South Carolina library has 11.
