My daughter needs biographical information about all three inventors
of the typewriter and we have been searching for days.  Please help. 
Their names are:  Christopher Latham Sholes; Samuel W. Soule; Carlos
Glidden.  Thank you.

Natalie47 --

I checked the Gale Group's Biography Resource Center, which includes
references to a lot of out-of-print books -- but which is available
online for free at many public libraries (it's a fee-based service, so
it's not available at no charge over the Internet).  The biography
resource center has extensive profiles of Christopher Latham Sholes,
though I could find nothing about Soule.  There are two Gliddens who
are noted inventors but not a "Carlos Glidden."

My next suggestion -- a Google search for the following terms:
typewriter museum

You find sites like the following:
http://www.typewritermuseum.org/

Now use Google to do an advanced search using your inventors last
names.  I did a site search for Soule and turned up the following at
the Virtual Typewriter Museum.  You'll see that all 3 gentlemen are
mentioned here:
