The International Tuba Euphonium Association hails from the U.S.A. for all Baritone, Euphonium & Tubists world wide. They publish a quarterly magazine which is excellent, reveiwing new music, CD's and performances etc. as well as archive material. The Tuba Journal carries a very comprehensive list of music for low brass, post free, usually with end of season discounts in the Winter. Obviously the majority of it's readership is American, but there is a growing interest here in the U.K. and both Stephen Mead and Cliff Bevan contribute. Their on line site is at http://www.iteaonline.org/ This is a specialist magazine just for low brass which deserves greater recognition by this countries players.
