Don't know what to say.  Crawling through the source for "file" at [1], 
the pattern matching code as in place as of Sept 2011.  It could be 
present earlier than Sept 2011, but I stopped hunting for it.  The 
earliest it would have made its way into the magic db would have been 
April 2011.

Perhaps OpenBSD is using some custom branch of "file", haven't updated 
the db, etc.

Yours,

Kevin

I haven't tested extensively, but it did identify the file as MARC21 Bibliographic record.  It also correctly identified a MARC21 Authority Record.  I'm running the most recent version of Ubuntu (12.04 - precise pangolin).
