There are many Wodehouse societies worldwide; here are the ones we know about:
The P.G. Wodehouse Society (UK). Yes, you guessed right, this society is based in the UK, although it has members worldwide. Their excellent newsletter is called Wooster Sauce and is well worth the price of membership, which is £22 per annum.
The P.G. Wodehouse Society. Based in The Netherlands, this is the oldest Wodehouse society and the only one whose existence PGW knew of in his lifetime. Please direct information and membership inquiries to Marcel Gijbels, Lammenschansweg 89, 2313DK Leiden, The Netherlands, or try this email address: firstname.lastname@example.org.
The Drones Club is based in Belgium. You can send them email or write to Mr. Kris Smets, Gijmelbergstraat 32A, 3201 Langdorp.
The Russian Wodehouse Society is run by Sir Watkyn Bassett (aka Mikhail Kuzmenko); contact him at Post Box 50, 115432 Moscow, Russia.
The Swedish Wodehouse Society or the WodehouseSällskapet has over 200 members (probably the greatest membership per inhabitant of any Society!). They issue several journals called Blandings Blandning (Blandings Mixture) and a yearbook called Jeeves. John Pettersson, the chairman, may be reached via e-mail, by telephone at +46 707 786408, or by writing him at Miraallén 57, 41758 Goteborg, Sweden.
