3. Organization
The Collection
Accessing Documents
The Electronic Data Book is composed of three main
groups of files: the installation files, Adobe Acrobat
Reader with Search 3.01, and the collection. The
installation routine will guide you through the setup
process; Acrobat Reader is the engine that powers the
Electronic Data Book; and the collection is the content
of the printed Data Book along with ancillary Acrobat
document files that provide added functionality and
assistance to the Electronic Data Book user.
The collection contains a separate Acrobat document
for each of the 26 Sections in the Data Book, another
for the main screen that you see when you opened the
Electronic Data Book; a Table of Contents that gives you
access to the Sections and introductory material; and a
fourth, Data Book Help, that you are now reading.
You may access any of the documents in the collection
at any time during a session. Continue on to the next
page for some tips that will quickly help you get the
most out of your Electronic Data Book.

4. In All Its Glory
Inside Scoop
User Tips
The Electronic Data Book screen may not be a pretty
picture, but then it’s designed for functionality.
Previous Acrobat users will immediately recognize it,
since the Electronic Data Book uses the Acrobat
toolbar and menu system for its power and flexibility.
However, whether you are an Acrobat newbie or an
old pro, a few minutes spent reviewing the next
several pages will give you the inside scoop you need
to efficiently find your way around the Electronic
Data Book.

5. Ideal Screen Settings
Just Gettin By
The page views in Electronic Data Book are optimized
for a screen that has an 1152 pixel x 864 pixel
desktop area (set in the Display window of your Windows
Control Panel). This resolution was selected because:
• It is commonly available on today’s monitors.
• The font sizes of the printed publication, from
which this product was adapted, are relatively
small and require at least this size to display well.
• To display as much of each page as possible, so
that the user does not become “lost” without any
margin references.
A monitor resolution as low as 800 x 600 will provide
somewhat viewable results. Any Windows-compatible
color monitor capable of displaying these resolutions
is sufficient.
If your monitor is not capable of the optimal setting
above, you may have to vary from the instructions in
this help file to attain viewable results. A feature of the
Data Book that users with lower resolution monitors
may appreciate is the Acrobat article mode. If you have
the Hand Tool selected and there’s a down-arrow in
the center of the mouse pointer, you can click to zoom
in on a single column of text. The Reader Online Guide
has information on navigating with articles.

6. I Can See Clearly
Setting your windows to an optimal configuration
will greatly enhance the ease with which you move
around the Electronic Data Book. Use the illustration
below as a guide for positioning the Sliding Bar with
your mouse. Of course, your monitor settings and
personal preference will influence the best position for
your situation.
Each page and figure in the Electronic Data Book is
programmed to fill the available width of the
Document Window. Moving the Sliding Bar to the left
will make the type larger.
Moving it to the right will
reveal more of the words
in the longer bookmarks.

7. Use Those Bookmarks!
Jumping to Other Documents
Getting Rid of Unwanted Clutter
Each section has a hierarchical list of topics and
figures in a separate window on the left side of the
screen. Click on the icon or text to jump to that topic.
This is the key to quickly finding what you want in
the Electronic Data Book. Note that the bookmarks for
the figures follow the topical list for each Section, .
In addition, there are extra bookmarks at the top of
the list to help you navigate outside of the current
document to other sections (e.g., Table of Contents
bookmark, ) and to help you get your screen set up
to the recommended configuration (the Viewing
Recommendations, ). To view hidden bookmarks,
use the horizontal or vertical sliders, , or the arrow
buttons, .
You can also hide lower level bookmarks so that only
a higher level topic list is completely visible. Your
Electronic Data Book comes with all the levels
expanded (except in Section 26 with the Classified
Listing of GPSA members). Any bookmark with
subordinates expanded will have a button, , to the
left of it (and the subordinates will be indented below).
Those with collapsed subordinates look like .7

Previous View button (see “E”, above)
nine times to return to where you
were reading. If you’ll be spending
some time browsing around the
figure, note the topical bookmark
you’re reading in, so you’re always
just one click away from where you
were.
To Return to the Table of Contents
All documents have a “Table of
Contents” bookmark in the
Bookmarks window on the left of
the screen. A single click of the
mouse will take you there.
To View a Reference
Superscripted numbers are
reference citations. References are
listed at the end of each section.
Take note of the number and use
the REFERENCES bookmark or the
Last Page button (on the Toolbar)
to jump to the list. If the number
you’re looking for is not within
view, scroll the page or use the
Previous Page button to take you
backwards until you find the one
you’re looking for. To return to
where you were reading, click
either the Previous View button ,
(up to nine times) or the topical
bookmark where you were reading.
To View the Bibliography
Bibliographical entries, when used,
are located with the references at
the end of the section. You can
navigate to them using the
BIBLIOGRAPHY bookmark or in the
same manner as described above in
To View A Reference.
To See Additional Pages
of a Multi-Page Figure
If the data you’re looking for is not
on the page that a figure link took
you to, there’s a good chance that
the figure is continued. This will be
indicated by a down-arrow in the
center of the hand pointer (when
the Hand Tool is selected). Click

10. Acrobat article. Repeated clicks
(about three, depending upon your
viewing conditions) will step you
down the entire length of a page.
To Follow a Column of Text
The printed Data Book was
published in a two-column format.
This Electronic Data Book remains
faithful to that, so from time to
time you will find yourself at the
end of the left-hand column and
want to continue reading at the top
of the right-hand one.
You can do this by displaying the
text as an article:
With the Hand Tool selected,
position the mouse pointer over
the column of text you’re
reading and click on it. This will
change the display to the article
mode and place you at the top
of the current column of text
you are reading.
For a full column of text, click
about three times and,
depending on your viewing
conditions, you’ll be back at
the bottom.
Click one more time and you’re
at the top of the next column.
If it’s more convenient, you can
remain in this mode for as long as
you are reading the same article.

Reader Online Guide for more

Book menu bar, or at any time via

11. Needle in a haystack? No problem.
Trying to find a particular word or phrase? The
Electronic Data Book (via Acrobat) gives you two
ways to do it. The first, and most limited, is the
Acrobat “Find” command. It allows you to locate any
combination of characters in the current Section (or
document) only. See the heading, To Search the
Current Section Only.
When you’re not sure what Section will contain the
data you need, or you want cross-disciplinary
information, then the Acrobat Search facility is what
you’re looking for. This powerful search engine will
perform a full text search of the entire Electronic Data
Book in seconds and return a list of the Sections and
ancillary files in which your search string appears.
See To Search All Sections.
Additionally, you can launch an Acrobat search from
the menu bars that appear at the bottom of the Main
screen and the Table of Contents screen.

Note
Although Acrobat will perform full
text searches, many of the figures are
bitmapped images and the text they
contain will not be located during any
type of search.

12. From a Data Book Menu Bar
You can immediately launch a
search when you start the GPSA
Electronic Data Book from either the
Main screen or the Table of
Contents screen.
Click on the [Search] button at
the bottom of the screen. The
Search dialog will open.
Type a search string, select the
desired options and click on the
[Search] button. Acrobat will
jump to the first occurrence, if
it is found.
Press [Ctrl]+U to go to the next
occurrence.
To Search All Sections
On the Acrobat Reader menu,
select Tools> Search> Query. The
Search dialog will pop up.
Place your mouse pointer over
the Find Results Containing Text
window and click once to get a
blinking cursor in the window.
Type a search string, select the
desired options and click on the
[Search] button.
Press [Ctrl]+U to go to the next
occurrence of a search string.
To Search the Current
Section Only
On the Acrobat Reader menu,
select Tools> Find.
Type a search string in the box,
select the desired options and

Trouble
If the [Search] button is grayed out
when the dialog box opens, the
probable cause is that the links to the
index files are broken. To restore them,
see Re-linking Indexes, below.

Re-linking Indexes
If you have attempted to search the
Data Book and found that you
didn’t have any indexes to search,
don’t panic. The index files (*.pdx)
are most likely still in the DataBook
Docs folder. A broken link is the
most likely cause. To reestablish
the link(s):
If the Adobe Acrobat Search
dialog is still open, go to the
next step. If not, select Tools>
Search> Query from the Acrobat
Reader menu.
Click on [Indexes]. The Index
Selection dialog will open.
Note the Available Indexes
window. There should be two
indexes listed, the Data Book and
Acrobat Help Files and the GPSA
Electronic Data Book. If the one(s)
you want to use are not shown,
click on the [Add] button.
Browse to the Data BookDocs
folder on the CD. Two PDX files
are listed, choose the one you
want and click [Open]. Repeat
these last two steps if you want
both indexes open.
Congratulations, your indexes are
now linked! Note that in the Adobe
Acrobat Search dialog, the [Search]
button is no longer grayed out. You
may now search all the files in the
Data Book collection for any phrase
that will point to information you’re
looking for. See To Search All
Sections for tips on using the
Search function.
