The Illustrated Directory of Guns

very good graphic presentation, but extremely few details for each gun, and even those are mostly about caliber, length and so on, the historical details being mostly overlooked. The fact it is only in inches and so on makes the reading difficult for, well, the rest of the planet (silly them, using logical measurements not worth mentioning in this Murican book). There are also some editing mistakes (an article starts on a page but is not continued on the next or anywhere else).
It is useful just for identifying guns. Which nowadays one could easily do online, by googling....
