This is Shakespeare. What you don't need from me here is a review of the content, suffice it is to say his works are presented here complete and unabridged, and the added content is extensive and intriguing, especially to any scholars of The Bard out there.
Having sampled a number of 'Complete' editions for Kindle, it soon became apparent that there were a range of options, all with their own pros, cons and quirks, from poorly presented text (e.g. one had everything wedged together, no line breaks and only italics used to separate dialogue from everything else), lacking (or absent) contents pages and shoddy (or absent) browsing, to misplaced stage-directions and even missing lines (seriously!).
The stand-alone plays seem to fair much better in the formatting department than the complete works, but if it's a single collection you want, with all the trimmings, then this DELPHI CLASSICS edition is the edition I'd recommend (be sure to check the link at the top of this review, as reviews seem to be shared across a range of similar products). As I said at the beginning, this particular edition contains not only the complete plays and sonnets, but a vast array of additional works and extras to compliment and flesh-out everything (including biographies, illustrations, photographs, background information on each work, etc.). It features a full and fully-linked contents page, as well as linked contents to each individual work, and, although the text is a little cramped, it is clear enough to easily distinguish between character, dialogue and stage-direction.
As far as I can tell, no Complete Works collection on Kindle is perfect, but this Delphi Classics edition appears to be the best of the bunch.
