Though complete in itself, this volume is a 'supplementary' to the book Errico Malatesta: His Life and Ideas, compiled by the same editor, which includes in its 311 pages not only 200 pages of Malatesta's writings, mostly translated for the first time, but also a 42 page 'Notes for a Biography' as well as the editor's assessment of Malatesta's 'Relevance for Anarchists Today' (40 pages)

The importance of this volume is that 23 articles published between 1924 and 1931 —the last year of his life — have been translated in full for the first time, and have been selected, as the sub-title 'polemical articles' makes clear, because they deal with issues which were of much concern amongst anarchists and which this editor, himself involved with anarchist propaganda for some 60 years, considers to be as relevant today as when they were written.
