Query: Good book, but poorly edited...

If you're looking for a little book that has a lot of info, then this is a good one to get. Very self explanatory in the title, the book has lots of basic/fundamental theorems, facts and formulae, ranging from algebra, trigonometry, physics, chemistry, computers and more.The only issue that I have with the book is the editing. I have found several double words (and and), and I have not even finished reading it all yet! Aside from that, it's a good book to look things up, and to learn from.
