Just purchased the 'full size' hardback copy of "The Natural Navigator" by Tristan Gooley as part of the wife's Xmas. (Size is 22cms x 16cms.) After some thought decided to get her the advertised 'pocket size' version as well so she could take it with her when she goes walking. I purhased this, in hardback, only to find it is in fact 20.5cms x 13.5cms in size. Just under 'full size' version. Not really what I was expecting, I was expecting something that would actually fit inside a normal pocket (as implied) for easy access and reference. The content is brilliant etc, no complaint there. Would Amazon consider printing the dimensions of a book when they advertise it? (especially 'pocket size' versions!) It would be a useful exercise to enable customers to visualise the book, especially those advertised as 'pocket' type publications.
