Subject: Re: Scientific investigations map from USGS - changes in
existing map and book series

A couple of months back (6? 8?) I
read a brief notice from the USGS Library
about the changes in existing map
and book publications (which of course
now I can't find - probably in my to-do
stack). Many of
the folded-map series are going
out of existence, and I accordingly
changed the catalog records in
my library's online catalog. One
that I haven't changed yet is the
record for the SI series; as I remember,
the numbering continues as if
it's still the I series, but the
series name changes.

If some kind soul from USGS doesn't
write in about this, you might want
to send an email to the USGS Library
and ask for information about
the various series' changes.

I remember an annnouncement a while back that several types map --I, HA,
MF, WRI--were being combined into Scientific Investigations Maps,
continuing the I numbering.
