I attended the International Map Trade Association show here in Denver
last week.  I went to 2 sessions regarding gov't publications.  The first
was a gripe session between map dealers and USGS.  I learned a thing or
two:  USGS has assigned ISBNs to ALL its publications (topos, bulletins,
professional papers, etc.).  If i understood it correctly, USGS will in
the next 18 months publish updated copies of the "Catalog of topographic
and other published maps"--the brown books.  The dealers (and I) were
very pleased to hear this.
