Good to know that the organization will continue in some form. The journal was always interesting to read and was one of the few places that published reviews of modern bands that play traditional jazz. Most publications tend to only be interested in reviewing reissues and restorations of the historic recordings in that style from the 1920's and 1930's. Perhaps the journal could continue in an online only version to save on printing and mailing costs (or at least until the IAJRC turns a profit again).
A stronger online presence would definitely help. The website was updated infrequently, and younger record collectors might not see a reason to visit it regularly or join. If either an online only version of the journal or, if it ceases publication, an online database of past issues become available, then it may help to offer free "sample articles" for non-members to look at to entice them to join. A survey of current members to learn how they found out about the IAJRC, why they decided to join, and what their favorite perks of being a member are could also assist in saving the IAJRC.
