In 1997, Nikita Plaksin and Andrey Kornilov published the brochure "VozvRAshtenie k Istokam" dealing with the collected retroanalytical works of Alexey Troitsky. Almost all problems (47) are supplied with detailed solutions and comments. The brochure also includes a discussion on Troitsky's influence on modern-day retrograde analysis.
Initially published in 100 copies only, this work is now impossible to obtain.
Presented here is a new, revised electronic edition. It was compiled with the kind permission and support of both authors and edited by Andrey Kornilov. Notes on recent developments (new works uncovered and new corrections composed) are included as well.
