Thanks for inspiring me to try again on Worldcat, Sarochka! I don't know why I couldn't pull it before. The successful access point was the name of the Winter Palace in Russian. It's The Winter Palace, St. Petersburg by M B Piotrovskiĭ; M F Korshunova; Tatʹi︠a︡na Borisovna Bushmina; Tati︠a︡na Borisovna Semionova; Emmanuel Ducamp
Publisher: Paris : Alain de Gourcuff Éditeur, Saint Petersberg : State Hermitage Museum, 1994 ; 1995. Now that see the catalog entry, I remember being surprised that it had some of the Anichkov rooms. The title implies Winter Palace only.
