Yes, strictly speaking the title should be the Anthology of Russian Symphonic Music, but this was a series originally issued on the Russian Melodiya label, and the translator was apparently not quite that proficient in English. This series was first issued on CD back in the late 1980s and early 1990s. (It was also on LP, although I am not sure how much ended up in each format.) It was not widely available here in the US, and the only CD store that carried them locally ran into financial problems about the time that these came out, and they could not obtain all of the releases. Thus, I was only able to purchase a selection of the titles when they were originally issued. Ever since, I have tried to obtain the missing volumes, and to establish the full list of items, at least as intended. (I have come to understand that several volumes were never issued, and a couple were perhaps planned but never recorded. Svetlanov apparently ran into problems with the Russian government about this time and became somewhat ostracized. I am also not sure that the set sold very well. Many of the better known items were available in other recordings, and the unique material may not have had such broad appeal.)
The series has been released by the Svetlanov Foundation over the last few years, which fills in many of my gaps, and helps me to fill in some of the details. (The new releases are completely reorganized, although individual CDs sometimes follow the order of the original releases. In several cases, individual items have been brought together from isolated issues in the original series.) I have also been able to pick up or locate copies of some of the volumes from the original series.
I don't know if anyone else might be able to provide some missing details, or would be interested in seeing the list as I have constructed it thus far.
