One of my favorite books about interior design is a product catalog from Vitra, which shows all their furniture through out the ages. Each furniture has it's full name, picture and information, and even witch year it was designed.
A lot of it is designed in the 20's and 30's, which I think is absolutely amazing! It's fantastic how inovative some people are, and how much of Vitra's designs that are timeless. Vitra is one of my favorites, and one of Vitra's designers were Ray and Charles Eames. I love to look through this book!
