Two things have severely limited the usefulness of this book.
a) When I look, say, East, I don't see bits of 2 big semi-circles of sky with a large blank space between them, which is what the star charts now show. What I do see is a continuous strip of sky as depicted in the yearbook 2001, when the star charts were printed as rectangles, which flow into each other. The former format was so easy to use, and the latter pointlessly difficult.
b) one of the most useful features for me (and surely for many others) of the Yearbook was its table of the Longitudes of the Sun, Moon and Planets, and it has been pointlessly removed. It took up only a single page, so a useful source of information has been removed for nothing.
