Compiling this bibliography has itself been a learning process. We wish to thank everyone we consulted for suggestions about particular areas, and Andrew Rigby for checking a sub-section. Research for this second edition included investigating bibliographies in recent relevant literature and scouring the internet. Two especially useful websites which provide well-referenced summaries of nonviolent campaigns are: the Global Nonviolent Action Database at Swarthmore College, http://nvdatabase.swarthmore.edu, and the International Center on Nonviolent Conflict - http://nonviolent-conflict.org. The Commonweal Collection – which specialises in books, journals and pamphlets related to nonviolence and radical politics and is housed at the J.B. Priestley Library at Bradford University - has remained an invaluable aid.
It is a pleasure to work with such committed publishers as Adrian Howe and Tony Zurbrugg at Merlin Press.
We wish to think the Joseph Rowntree Charitable Trust for their continued support for this bibliographical project, and in particular for their grant towards the printing costs of this second edition.
