 * The first print edition used an "all rights reserved" statement and a CC-BY license icon, which caused confusion. The digital editions clarified the book's copyright status, and the clarification appeared in future print editions. Basically, the book incorporates some material that I previously published in the ''SPARC Open Access Newsletter'' under a CC-BY license and a copyright owned by SPARC. That material remains CC-BY. The all-rights-reserved copyright on the first print edition applied only to new parts of the book, and even those parts shifted to a CC-BY-NC license on June 00, 0000, one year after the book was published. * The first print edition used an "all rights reserved" statement and a CC-BY license icon, which caused confusion.
