Thanks for the reply.
That is what I have also assumed, a date in the early 1990s. Am curious if the declassification date is known. Perhaps only to those with the "need to know" in Russia.
Cheers
Declassification is a complicated routine. Sometimes its traces can be found on book titles. Unfortunately BSSA carries no traces of dates for it.
I remember in the USSR there were quite many classified publications carrying the lowest "DSP" signature.
Even in my university I know some dissertations, which were far away from military subjects, but carried this signature and needed a special routine to get access to. Anybody could take them, but needed to persuade librarians that you really need this dissertation
BSSA had the same signature., i.e. it was available for anybody, but in specialized library section with special documents prooving your interest....
