AN EXAMPLE OF HOW TO LOOK SOMETHING UP,
USING CHARTS OR THE INDEX:
Suppose someone has swollen glands (swollen lymph nodes) and you want to
know the possible causes. There are 3 places in your book where you might look.
1. The Guide to Identification of Skin Problems—pages 196 to 198 of Where
There Is No Doctor. This has drawings and descriptions of various skin problems.
You can see what each problem looks like up close, and where it usually occurs on
the body. The possible causes are named, and page references are given.
To make the best use of this guide, health workers need to understand how the
information is organized.
Problems that look similar
are grouped in the same
box.
There is a box for each of
the following signs:
• small sores
• large open sores
• lumps
• swollen lymph nodes
• spots or patches
• warts
• rings
• welts or hives
• blisters
• rash
Eache vertical column on
the chart gives a certain
kind of informations:
picture of
what the
problem
looks like
up close
details about
possible causes
of the problem
drawing of each
possible cause,
showing where it
may occur on the
body
name
of the
disease
page
in
WTND
2. Discussion of swollen
lymph nodes-page 88 of WTND.
This has a picture showing places
on the body where swollen lymph
nodes can appear with different
problems. But no page references
are given. You have to look up
possible causes in the index.
3. The INDEX (yellow pages) of WTND also can
be used as a guide to possible causes of health
problems. It does not provide any details, but it lists
the pages on which you can find more information.
When in doubt about the cause of a problem, be sure
you check all of the page references. Some may be
more helpful than others.
