"Hints on Scanned Documentation"

The scanned documentation noted here is contained in the \docu-
ment directory on the CD-ROM as .gif files.  These files can be 
read by any computer program that reads PC Paintbrush <tm> format 
files.  The GeoVu software provided on this CD-ROM contains such 
a utility.

To use the GeoVu utility, merely select the appropriate file from 
this menu, using the "Open Data" option that you have been using 
to this point.

If you are VERY NEW to GeoVu, you can open a file by

1. Selecting "File" from the options at the top of your screen.
2. After selecting "File" select "Open Data" from the options 
that appear in the pull-down menu.
3. Follow the hierarchy of menu paths to the data of your choice.
4. When the hierarchy leads you to a topic "Scanned Documenta-
tion" merely select that topic.  The next topic should read "Page 
1, Page 2,... etc." or "Paper 1 Page 1, Paper 1 Page 2, .... 
Paper 2 Page 1.... etc.  You can select the pages manually, or 
create a "slide show" under the Utilities option at the top of 
the screen.  The first time the .gif file displays it might be 
reduced in size.  This is a "feature" of current versions of 
GeoVu that might be improved in the future.  If you redisplay the 
image (by selecting "Search" from the options at the top of the 
screen, then "Create" from the menu thus pulled down, you can 
modify the parameter that sets the sampling rate from "n" [usual-
ly 2, 3, 4, or 5] to 1).  This will give you full resolution 
display of the scanned documentation.

It should be noted that this scanned documentation is a compro-
mise.  We originally attempted to use optical character recogni-
tion software to convert the scanned documentation to more usable 
text.  However, the technology was too immature at the time of 
scanning (1992) to use successfully.  Indeed, as of this writing 
(late 1995) the technology is still too immature for convenient 
application to this problem.

Thus, we present the scanned documentation as images.

NOTE: Many of the original documents are not copyright, and may 
be reproduced freely.  However, several other documents ARE 
copyright. The National Geophysical Data Center has obtained 
permission to reproduce all documents with a valid copyright.  
However, this permission does not pass automatically to anyone 
else.  Thus, though all of the data on this CD-ROM are unre-
stricted, much of the scanned documentation (which contains 
copyright notices) may not be distributed further, without per-
mission of the copyright holder, or without a dontribution made 
to the Copyright Clearance Center under the rules noted in the 
individual papers.  (Also note that a few documents authored by 
U. S. Government employees or contractors as part of their work 
for the Government, had copyrights claimed by the journals that 
published the papers. Such documents are not subject to copy-
right, and the copyright claims of said journals have been deter-
mined to be meritless.)
