I have individual (occasionally 2 or 3) spare copies of the following issues of International Socalism (1st series), the (successively) quarterly, bi-monthly and monthly journal of the British International Socialism group/International Socialists (IS) and (from 1977) Socialist Workers Party.
The first is n° 37 (June/July 1969), edited by Colin Barker, with articles by Sheng-wu-lien with an introduction by Tony Cliff ('Whither China?'), Paul Mattick (on Mandel's economics), Andrew Sayers (on the Italian left) and Part One (Part Two famously did not materialise) of 'George Orwell, International Socialist ?' by Peter Sedgwick.
N° 61 was a special double issue with longer articles by Michael Kidron ('Imperialism, highest stage but one' and 'International Capitalism'), Tony Cliff ('Permanent Revolution' and 'China in Crisis') and Colin Barker ('The British Labour Movement: Aspects of Current Experience').
All good stuff.
It is of course necessary to point out that many, if not all, of the articles in these journals can be consulted on line (for example at http://www.marxistsfr.org/history/etol/newspape/isj/index2.html )
However, if there are any collectors out there, here is the complete list of issues available. They can be picked up at Marxism 2015 in London in return for a donation to Socialist Worker. Or contact me at colin.falconer @ hotmail.fr
N°s 37, 41-43, 48, 50, 53, 55-57, 59-74, 76, 78-80, 83, 89, 94, 96-99, 101-104.
