There have been other series book conferences and conventions, of course. Nancy Drew has had several major conferences. The La Crosse, WI, and Corning, NY, series book conventions were legendary for the guests which included several series book authors. The 1994 Series Book Collectors in Earthquake Land in Los Angeles, CA was another good one. Smaller regional gatherings of collectors have also been held.
The Society of Phantom Friends holds annual gatherings for enthusiasts of all girls' series books. The Horatio Alger Society also has annual conventions, usually in May.
The Popular Culture Association has an annual conference, usually in the Wednesday through Saturday before Easter. The Mar 31-Apr 3, 2010 conference will be held in St. Louis. I have been participating in that conference annually since 1992 and presented papers each year except for 1993 and 1994.
But no Tom Swift convention. Realizing that 2010 would be the 100th anniversary, I mentioned my intent to host a Tom Swift 100th Anniversary convention in my home town of San Diego, CA, to a Tom Swift Yahoo Group (Tom-Swift).
The idea was welcomed and some were enthusiastic enough that they said "why wait?" and begun plans for a smaller convention in Hammondsport, NY, from Friday July 24 through Sunday July 26.

Why Hammondsport? That was the home town for Glenn Hammond Curtiss, the motorcycle and aviation pioneer who is considered by many to be an inspiration for Tom Swift. Many of the things he did are similar to those described in the early stories. He did many of his experiments in Hammondsport on Keuka Lake. These are therefore models for Shopton, NY, and Lake Carlopa of the stories.
At least part of the event will be held at the Glenn H. Curtiss Museum in Hammondsport.
We expect a small gathering at this year's event, perhaps a dozen of the most enthusiastic Tom Swift fans. If someone reading this wants to attend, there should still be some room.
In the coming week before the convention, I'll write a bit more about it and of course I will have some photos and summaries of the convention afterward.
