Mitochondrial genetics is a fascinating research frontier on 
several grounds: recent research has identified mtDNA mutations as the 
cause of a number of degenerative diseases (among them Huntington's 
Disease); evidence of the mitochondrial genome provides a sensitive 
measure for BOTH intraspecies and interspecies genetic variation --and is 
applicable to questions in forensics, in population ecology, and in 
studies of evolutionary divergence.  This is hot stuff.

But this search in Annie is somewhat disappointing --only ONE book that has 
'mitochondrial dna' in its record.  So what's the big deal?

	*part of the answer is that the literature on the subject
	is not really IN books, or anyway not nearly so much as it
	is in periodical literature, which we'll examine next week

But it's worth looking at a larger library to see if we're missing 
something entirely.  Here's what Harvard's HOLLIS yields:

research going on and being reported in books, but the real action is in 
periodical literatures, as we'll see.
