June 2011 deposits at ICPSR

June 2011 was a very busy time for our deposit system.  The number of deposits was pretty typical, but the number of files was enormous.

153	2	video/unknown

In addition to the usual suspects like plain ASCII, SAS, SPSS, MS Word, PDF, we also have some of the usual problems, such as files being reported by the automated checker as containing C or C++ source code, when the truth is that they are likely text/plain instead.

One interesting data point is the pair of deposits that contain video files, and lots of them.  Upon further review these appear to be vintage SPSS files for the IBM PC.  Here's a string that appears in all of the files:

SPSS/PC+ System File Written by Data Entry II

and here is another one:

PCSPSS SYSTEM FILE.  IBM PC DOS, SPSS/PC+ V3.0

From a timestamp located nearby, it looks like these files were from 1994.  Or maybe they were moved from a mainframe to a PC in 1994?


And there are a few others on the list above that would benefit from some human scrutiny as well.
