Bob,

you are probably referring to the small format books put out by Ceramics Monthly - information in these books has been taken from various issues of the magazine over the years. This little series is edited by Barbara Tipton.
You can most likely get ordering information by going to the Ceramics Monthly web site Unless they have updated any of them they are easily 10+ years old by now and some information not as relevant or changed - other information is good for ages to come. great to have in ones' library.
