I highly recommend buying the book “The 100 Best Business Books of All Time”, with condensed versions of 100 very important business books. I might also refer you to the beast that “Business: The Ultimate Resource” is (>2000 pages, with lots of 1-page book summaries).
The recomendation isnt in full though, since some books arent included which I find really relevant for each category. So here are a few additions, some of them which are more of a personal nature:
SALES AND MARKETING
RULES AND SCOREKEEPING
INNOVATION AND CREATIVITY
