I found and scanned the original 1918 edition of Bogdanov’s collection of essays called Вопросы социализма [Problems of Socialism]. These essays are all available in the 1990 version of the book with the same title – that edition contained many more essays and can be found online as well. The original 1918 edition included only 6 essays while the 1990 book includes many smaller collections that Bogdanov published over many years.

Enjoy!
