The 16th edition of the Chicago Manual of Style is, however, now available. Among other updates, this edition boasts Chicago’s first explicit guidelines for citing Kindle editions and publications (§§14.166; A.38). Although I have yet to be able to examine this new edition first-hand, on a cursory perusal, these guidelines appear mainly to be an additional application of the instructions for citing electronic books in Chicago’s 15th edition (§§17.142–47). More information on this new edition of Chicago is available at Chicago Manual of Style Online.
