 ## Notes
 
-- EN↔RU title pairing source:
-- Identity check (same person?):
+- RU professional source (education-psy.ru, sandplay reading list) states explicitly:
+  «Официальное русское издание отсутствует»; commonly rendered «Исцеление и трансформация
+  в песочной терапии» (informal translation).
+- Not in cogito-shop, not in livelib sandplay selection (listed under the EN title only).
+- Identity note: author is **Ruth** Ammann (Рут Амманн), Kalff's student — don't confuse
+  with Robert Ammann (mathematician) or other Амманн.
