The best addition to any collection are good resource books, the purchase of a few books is usually less than the cost of the collectible and could save money in the long run. Become informed about your collection, no matter what it is. Cookie jars are no exception, buy a book and find out more about what you're looking for or have found.
Author Mike Schneider's book should be the first purchase in a Cookie Jar Book library. Although there may not be as many pictures of jars, this book has the best resources for finding out more about the companies, pictures of marks and measurement of jars. The last book was published in 2005.
Ellen and Mark Supnick produced the largest book on cookie jars, with over 423 pages of pictures. This book has the most cookie jar pictures, but the pictures are small and it can be hard to see some of the details. But, if you want one book and want to see the "most" jars, this is the book for you.
The Roerig's first published this book in 1991, but numerous updates have kept it fairly current. This book, along with the other two Roerig books, are excellent resources. If you can afford it -- get all three of them. This volume is no longer being published and will have to be found in used condition.
4. Collector's Encyclopedia of Cookie Jars Book IIThie edition was first published in 1994 and is almost 400 pages of cookie jar fun! Lots of pictures as the Roerigs cover items not shown in book one.
Published in 1998, the third edition addresses the reproduction issue. A valuable list of known reproductions (at the time of publication) will help the collector become more aware of what to look for.
6. McCoy Cookie JarsThe Harold Nichols spiral bound book of McCoy jars was published in 1991.It is no longer in print, but can sometimes be found in used condition. If you can find it, Buy It! Although prices have risen quite a bit since publication, the complete index of all the McCoy jars is invaluable.
7. An Illustrated Value Guide to Cookie Jars, Book IThe first cookie jar book that was published (1983), lots of pictures but not much information. You can usually find this book used for just a few dollars -- at that price it's nice to have.
Ermagene Westfall published the first cookie jar price guide, that I am aware of, in 1983. Book I was a small pocketsize book with little description, but good pictures. Ten years later Book II was published in a larger format and with a little more detail. Although I don't use these as often as the other books, they nicely round out my collection of resources.
It's been a long time since we've seen a book from the Roerigs and this book has a new name, Ultimate Encyclopedia. The latest offering from Fred and Joyce Roerig is mainly a re-do of their previous books, complete with the same pictures.
If you love cookie jar collecting, add this book to your collection. You can never have enough books showing jars and prices. But if you're looking for information on newer jars (after the mid '70s) this book isn't for you. Warman's Cookie Jars (author Mark Moran) covers the 1930s to the early 1970s.
