Both of those books have been extensively discussed in previous threads.
Here is one:

Reviews of Lasker's Manual were harder to find. There were a few threads but most of the responses came from people who hadn't read it.
There are several versions out. Corrections have been made. There is one with an introduction by Mark Dvoretsky that looks very good.
I would be very grateful if someone gives me a detailed review of the books 'Bobby Fischer Teaches Chess' and 'Emanuel Lasker's Manual of Chess' (how many puzzles are there, are the games analysed, are they for intermediates, are the solutions to the puzzles correct etc).
