Where is paper I? Usually papers with Roman numerals have otherwise
identical titles. Perhaps paper I is

http://adsabs.harvard.edu/abs/1964SvA.....8...13Z

@ARTICLE {YZeldovich64a,
AUTHOR = "Y. B. Zel'dovich",
TITLE = "Observations in a Universe Homogeneous in
the Mean",
JOURNAL = SVA,
YEAR = "1964",
VOLUME = "8",
NUMBER = "1",
PAGES = "13-16",
MONTH = jul # aug,
NOTE = ""
}

which is a translation of

@ARTICLE { YZeldovich64ao ,
AUTHOR = "Y. B. Zel'dovich",
TITLE = "",
JOURNAL = "Astronomicheskii Zhurnal",
YEAR = "1964",
VOLUME = "41",
NUMBER = "1",
PAGES = "19-24",
MONTH = jan # feb,
NOTE = ""
}

I would like to know the original titles of the Russian papers. Perhaps
someone has access to them, or could even point me to an online
version and/or send me a PDF file generated from a scan.

Is the Zel'dovich paper actually paper I?

While I'm at it, there is "paper III":

http://adsabs.harvard.edu/abs/1966SvA.....9..671D

@ARTICLE { VDashevskiiVSlysh66a ,
AUTHOR = "V. M. Dashevskii and V. J. Slysh",
TITLE = "On the Propagation of Light in a
Nonhomogeneous Universe",
JOURNAL = SVA,
YEAR = "1966",
VOLUME = "9",
NUMBER = "4",
PAGES = "671--672",
MONTH = jan # feb,
NOTE = ""
}

which is a translation of

@ARTICLE { VDashevskiiVSlysh66ao ,
AUTHOR = "V. M. Dashevskii and V. J. Slysh",
TITLE = "",
JOURNAL = "Astronomicheskii Zhurnal",
YEAR = "1965",
VOLUME = "42",
NUMBER = "4",
PAGES = "863--864",
MONTH = jul # aug,
NOTE = ""
}

Again, perhaps someone can provide me with the original title and/or
access to the paper.

Unless there are obvious differences in length, my Russian is not good
enough to determine how closely the translations follow the original.
Since two of seven figures in the Zel'dovich paper are not mentioned in
the text, perhaps the translations are condensed.
