Bought in iberlibro. I thought it was more computer-related, although the publishing date (1982) should have told otherwise. Anyway, it seems an interesting read.

Maybe it's not a book you can learn from, in the sense "I didn't know before, now I know"; it can open some new ways of looking at problems, of considering more points of view. Maybe the lesson is there are more possibilities of reasoning when confronted with a problem.
In every chapter a problem is presented, and the reader is asked for a solution, or an impression at least. The bad thing is you can't ask for the missing information, so it is difficult to go on the way the authors do.
And it includes a chapter about a computer-related problem, only it is not about programming, but more about the related human factor.

One of those which will make it into Geomni Free Library's take #1!
