Julie,

I'd consider as primary sources as those materials contemporary with the
event being studied. A map of Europe created in 1944 would be a primary
source if WW2 was being studied. A map created today, showing Europe in
1944, would not be primary. The 1944 map would not be a primary source
if
the unification of Italy was being studied.

The existence of older items on the map is a red herring. A newspaper
account of an event will mention things, like roads, that have existed
for
quite some time. So may a map.

Good question. Made me stop and think.

Sincerely,
David Bigwood

Hi all,

I got this question from one of the students that took my map
librarianship
class at San Jose State's Library School this past summer.  I was hoping
to
get your thoughts

>Or, can they be anything that uses original data?

Here was my "off the cuff" answer to her.

Now, as far as your reference question goes, I would say it depends, but
in
general, yes, I would call maps primary sources.  The strange things
about
maps is that they are a composite of everything that came before.  So, a
detailed map of California shows the El Camino Real from San Diego to
San
Francisco.  That road, and before it the trail, has been around for a
couple of hundred years.  It's on every map of the area you see.  Do you
have to go back to the early maps to call them primary?  Do you only
take
manuscript maps as primary material?  We don't do that with books.

Then, is GIS data primary material?  Only if it's the original work of
an
author.  In your GIS project, you may collect data points on your own,
say
the types of trees on the Stanford campus.  You could then lay this
primary
source information over the street data from Navtech or the Stanford
Maps
and Records office, etc.  Also, GIS data is simply that, data.  It in
itself is not a map.  You must use the correct software in order to make
it
a map.

Any opinions?

Julie
