It is of course completely possible that the readers are mistaken about the 'mistakes', so please add if you know more!
Thanks to Bozulich for this great book. The lack of explanations in the book really motivates one to look further and work on the problems in depth.

However, White can obtain a seki by playing with and

Problem 300 is described as "Black to kill" and is in the section labelled "One-move problems - Black to kill" when it is actually Black to live.
"Black peeps at . If White a, Black b. If White b, Black c also kills White."
The c is omitted in the diagram.
Note: The c can be either of the two points.
The text says "Black creates a dead eye space. If White a, Black b. If White c, Black d."
However, there are no c and d on the diagram.
It is possible that the intended sentence is "If White b, Black a."
"corner" rather than "cornert".
Actually, Black can just connect his stones at a or b since White cannot make a false eye on the left. This way he does not have to sacrifice two stones to live.
Obviously, the stone should be removed from this problem for the intended solution to be the best solution.
Instead of , White can extend at
in Diagram 1, and Black does not have enough liberties to play at
, and so must capture the four white stones...
Now White can play back under the stones to form a 10,000 year ko. The book states none of the "Black to live" solutions involve ko...
/Problem 752 - Mannenko Discussion
The book explicitly states that there are no problems that need a ko to solve, but in this one the answer doesn't mention a move by white that forces a ko!
The solution given in the book:
And now we have an approach ko for white, which, if won, kills black.
( at
is a direct ko.)
The problem says "Black to kill", but White can live with this sequence.
Solution diagram gives as the solution. However, Black a works too.
The solution in the book shows this sequence as a solution. However, having to directly hit the vital point at
is also a solution (think incomplete bulky five).
