Published from 1985 as 'Ymgyrch Cymru' and from 1991 as 'Heddwch', the supporter magazine for CND Cymru - the Welsh Campaign for Nuclear Disarmament has been published roughly quarterly to the present day, and is an invaluable reference and source material on community action Wales-wide in support of global peace and internationalism across 4 decades.
(NB - there are some disparities in numbering of publications, but they become more sequential from 1987 )
