freebsdmall.com is not an official FreeBSD store, it is run by users to
help other users and to help the project by giving back profits from the
sales.

At freebsdmall.com there is an old copy of part of the FreeBSD Handbook.
This book (both vols combined) is a printed version of the official
FreeBSD Handbook available at FreeBSD.org - just an older version than
what is on the site today.

The FreeBSD Mastery books are written by Michael W Lucas, while he is a
BSD user and his books are highly recommended, they are not official
documentation from any of the BSD projects. He has other titles
available on his site - tiltedwindmillpress.com Each of these books
gives advanced information on one specific topic, like ssh or zfs but
they don't cover an entire system in one book.

The BSD magazine is another third party publication that is originally
from bsdmag.org

freebsdfoundation.org/journal is an official magazine from the FreeBSD
Foundation.
