there is a lot of confusion regarding the books authored by Ray mears, much of this stems from the fact that they all have similar names and some of them have been republished several times under slightly different names.
thus far there are ten books that I am aware of which where published in the following order:
Survival Handbook: Practical Guide to Woodcraft and Woodlore
ISBN 0946609888 - Publisher: Oxf. Illustrated P - Release date: 1990

Those marked in the same colors contain identical or near identical content
(some pictures may have been moved, removed or added with a different title and cover art in some cases it is simply a different format such as a large coffee table size or handbook size version of the same book)
the most difficult book to obtain is the first on the list in green (Survival Handbook: Practical Guide to Woodcraft and Woodlore ISBN 0946609888), all others are easily available
if you get one of the orange titles and one of the blue titles plus if you are determined the title marked in green, you will have all you require from Mr Mears offerings
other titles such as Ray Mears' World of Survival: As Seen on TV, and The Real Heroes of Telemark are more accompaniments to their corresponding TV series than serious instructional manuals
I hope this makes things a little clearer, please let me know if there is an error in the list so that I may correct it.
