Pocket Ref

Invaluable source of information if the internet goes down. Highly recommend

Excellent! I bought a whole stack to give as a Christmas present.

This is a must have everyone. Don't care how young or old you are. It's an amazing gift for ANY human being. I promise. ^_^

Most people would say that something like this has no place in today's instant search world, but I completely disagree. Check out the Table of Contents page; this thing is loaded with tons of basic information, as well as every kind of scientific or mathematical reference or formula you'll likely ever need. A family member went to school for engineering, this was the first thing I got him. Doing work around the house and need to figure out ceiling fan clearance or strength of materials? Everything you need is right here. If you do any kind of scientific, mathematical, engineering, carpentry, landscaping, or so many other things, you can't go wrong having this. You also can't beat the price!

fun item, inexpensive reference guide. Very wide range of information. enjoyable read, lots of useful and some not so useful information but handy. Print is very small so those with challenged near vision will need magnification.

Great little pocket reference. Lots of good information there and lots of not so interesting information.

Best book a DIY person could have. Best book a professional should have.

Great book of reference for many subjects. This book covers so many topics you are bound to find what you are looking for. First aid, electrical info, carpentry. Knot tying, metals and much more. I use this one a lot.
