Editor Jaime Snyder (Bucky's grandson) added a 22-page Introduction, a lot of footnotes, page numbers to the two pictures sections and smaller pages which added to the length.
There's some additional info in the back, and of course a new index & cover.
All in all it probably would be worth buying the new edition (paperback) even if one has the older 1963 edition.
