You don't know about me, without you have read a book by the name of "The Adventures of Tom Sawyer," but that ain't no matter.

I been there before.

Please keep the Norton Annotated Series books un-combined with the rest of them - it is significantly different with new material, pictures etc.. and it needs to be separate.
The Norton Annotated Series book is not the -- or "a" -- "standard" edition. Rather, it is the complete book, as Twain intended it, taken from the original final MS, half of which was missing for over a century. It is, therefore, a DIFFERENT BOOK IN TEXTUAL CONTENT.
This is the only "comprehensive edition" of Adventures of Huckleberry Finn. Which means: long missing and believed lost for good was the first half (over 600 pages) of Twain's final manuscript of the book. Some years ago it was found, by chance, in a trunk in an attic in California, then reunited with the other half in Buffalo. Upon reading it was found to contain materials that had been excluded by the publisher -- therefore from first edition onward the book was actually not wholly as Twain intended. Those portions are included in this edition (and in a more scholarly Mark Twain Project/Library edition), which makes it a different work than the heretofore "standard" edition/s.
