There are a few reference books with extensive historical information about fiberglass fly rods. I've attempted to acknowledge these sources on the various information pages. Additional specific sources, such as rod company catalogs, magazine articles, or websites are acknowledged on the info pages.
Reference 1: Far and away, the single best source for historical information on glass rods is "Fiberglass Fly Rods" by Victor Johnson and Victor Johnson, Sr. The book was published in 1996 by Centennial Publications. The book is available directly from Vic Johnson via his website Engineering Pathways. This book is a must-buy for a fiberglass rod collector.
Reference 2: The single best source for information on Fenwick rods is "Fenwick" also written by Vic Johnson and published in 2005. It is also available directly from Vic Johnson (the only way to get a signed copy). If you are a dedicated Fenwick collector, this one is a must-buy also. Finally, Vic Johnson also wrote "America's Fly Lines", the only historical treatise on fly lines that I have seen.
Reference 3: There is a chapter on fiberglass fly rods in Ernest Schweibert's masterwork "Trout" published in 1978. But the more useful source is the excerpted book "Trout Tackle Two" that was published by E.P Dutton in 1984. In "Trout Tackle Two", Schweibert updated the chapter with information into the early 80s. This chapter is a good snapshot of the fiberglass fly rod market of the 70s and early 80s. For what it is worth, there is a LARGE chapter on cane, a short chapter on graphite, and a little bit about boron, too.
Reference 4: A great compilation of the fly fishing market in the early 80s (including glass rods) is "The Compleat Angler's Catalog" by Scott Roederer. The book was published in 1985 by Spring Creek Press. This is a rather useful text for eBay buying of any fly fishing tackle of the era. I wish I knew of similar titles from both earlier and later times. (One of these every 10 years would be nice.)
Additional References: If you contribute to a page, please reference where your information came from, be it catalog, magazine, or advertisement copy. In the reference, give the name of the publication, date, author, and page number (if these items are available). If you are describing the details of a rod in your collection, please use the reference "Personal description". If the information came to you by e-mail, letter, phone call, or smoke signal, please use the reference "Personal communication". Whatever you do, don't take chunks of text and information from Vic's books. As I mentioned above, they are worth owning if you collect glass. Thanks - Tom
