We are excited to announce that the Volume One of the series is out now. Thus far we have four volumes out – from projected ten (or more) – so not exactly half-way done but getting close. The next volume will be Volume 4: Political Writings, 1904-1918 – it will include translations by both David G. Rowley and Evgeni V. Pavlov and will contain a number of Bogdanov’s political texts that have never been thus collected and presented in any languages. After that we hope to put out Volume 7: Writings on Socialism and Economic Science, 1904-1923 – translated by David G. Rowley and then Volumes 5: The Fall of Great Fetishism: The Contemporary Crisis of Ideology and Volume 6: The Cultural Tasks of Our Time: Essays on Proletarian Culture – translated by Evgeni V. Pavlov. We will then complete the planned ten-volume series with a translation of Tectology and a volume of correspondence (more details on this pending)

Alexander Bogdanov Library 
These resources are so valuable! We are all very grateful I am sure!
After reading Empriomonism and the Philosophy of living Experience, I am now deep enough into the Bogdanov rabbit-hole to be interested in these even earlier texts. So do you have an approximate release date for the paperback edition? As you know – it was the same with the other releases – at 192€ the hardcover edition isn’t really affordable for some of us proletarians at all…
Paperbacks come out a year after hardbacks (which are meant for libraries – you can ask a local library to sign up for the whole series or acquire this volume only). Haymarket will be publishing this volume 12 months later.
