“DPLA’s new initiative means libraries (public and academic) intend to continue to compete with Amazon, Barnes & Noble, Apple, and Google to be readers’ one-stop shopping place for ebooks and audiobooks.
“Why should you care? Because online library catalogs offer readers the best way to quickly identify books they want to read. No other provider of ebooks offers authors a comparable subject and keyword system to make their books so readily and easily available to readers.”
From Nancy K. Humphreys’ post on authormaps, “The Digital Public Library of America”
