Adobe Portable Document files can be very large. They are typically
about 75K bytes per page, and may run from one page to hundreds.
A 56K analog modem will download each page of a PDF file in approximately
15 to 30 seconds. Therefore, a very large PDF file may take 10 minutes
or even longer to load with such a modem. All PDF files are tagged
with their size in bytes, so that you can make an informed choice
as to whether it's "worth it" to view the file.
Note that the Table of Contents features documents as individual
scanned pages as well, and these are much quicker to download and
view. If you see a document in a search window that you'd like to
view but it seems too large, the entry should contain enough information
for you to find the scanned page set in the Table of Contents without
too much trouble.
When I click on a PDF icon, the Adobe
Reader doesn't load.
The Adobe Acrobat Reader is a separate program created by Adobe
Inc., and is freely downloadable from their web site. The Reader
is currently bundled with web browsers and many computer operating
systems, but if your computer is an older model, it is possible
you don't have it. If you're not sure whether you have this viewer
or not, click this link to test for the presence
of the Adobe Reader. If you were taken to a test PDF document,
congratulations. Otherwise, see the link below.

The Adobe Reader runs "standalone"
in its own window, not inside the browser window.
This shouldn't happen with Microsoft's Internet Explorer, but may
happen with Netscape's browsers. The solution, assuming you are
running under Microsoft Windows, is to hand-copy a particular DLL
file from the Adobe Reader directory to the Netscape plug-ins directory.
You can do this using the standard copy and paste techniques of
Windows Explorer. This file is named something like "nppdf32.dll."
The Adobe Reader plug-in folder will be something like:
c:\Program Files\Adobe\Acrobat5\Reader\Browser (folder will vary
depending on Reader version and installation folder)
and should be copied to a folder which may be named something like:
Unfortunately, the steps to fix this problem cannot be laid out
more exactly, as they depend on the version of each of these programs
(Adobe Reader and Netscape) and where each of these two programs
have been installed.
When I resize my browser to get a
better look at a PDF document, the Adobe viewer doesn't resize.
This problem may appear when under certain condictions viewing
PDF documents if you are using Netscape version 4. It is caused
by a "resizing" bug in that browser. The recommended solution
is to upgrade your browser to Netscape 6 (a free download from www.netscape.com
- clickon the Browser
Central tab), or use Microsoft Internet Explorer.
