Wikipedia
A coffee table book is an oversized, usually hard-covered book whose purpose is for display on a table intended for use in an area in which one entertains guests and from which it can serve to inspire conversation. Subject matter is predominantly non-fiction and pictorial (a photo-book). Pages consist mainly of photographs and illustrations, accompanied by captions and small blocks of text, as opposed to long prose. Since they are aimed at anyone who might pick up the book for a light read, the analysis inside is often more basic and with less jargon than other books on the subject. Because of this, the term "coffee table book" can be used pejoratively to indicate a superficial approach to the subject.
In the field of mathematics, a coffee table book is usually a notebook containing a number of mathematical problems and theorems contributed by community meeting in a particular place, or connected by a common scientific interest.
