Published from July 1934 to June 1996. It's former name was "Letters of Interest from the Home Field." According to Manchester Library http://www.library.manchester.ac.uk/search-resources/special-collections/guide-to-special-collections/christian-brethren-collections/printed-material/periodicals/ the magazine had been continued as "Interest" since 1969 until it's end.
I'm told: "A fascinating magazine which is very hard to obtain in the UK. – organ of the Chapel assemblies in North America."
See also "Interest Ministries - Celebrating 60 Years of Service to God's Servants and Ministries" (1994)
I have a full set of scans from 1965 to the end which I haven't put up yet, partly because I generally don't do material to close to present for privacy / copyright concerns, also cause it takes some time to go through these scans and prepare them. I may put another five or ten years up sometime.
The last issue is interesting, giving some history of the publication. In the latter years it evidently ran into a lot of dispute with the Assemblies, as it seems to have become quite broad church and operated a 'consulting' service to help struggling assemblies (some of you will know what that entails!). I have a 66 page document "An Apology from INTEREST Ministries" from around 1991 which goes into these issues, with various correspondence.
In the end it appears the increased cost of publication led to it's demise. Quite praiseworthy that it was always distributed free without charge, and only voluntary contributions, but in the end this led to it's demise. A smaller newsletter "News of Interest" took it's place (maybe after a few months gap.)
