There are 5 ways to find information in this collection:

You can search for particular words that
appear in the text from the "search" page. This is the first page that
comes up when you begin, and can be reached from other pages by pressing
the search button.
You can access publications by subject by
pressing the subjects button. This brings up a list of subjects,
represented by bookshelves.
You can access publications by title by
pressing the titles a-z button. This brings up a list of books in
You can access publications by

How to read the books
You can tell when you have arrived at an individual book because there
is a photograph of its front cover at the top left of the page. Beside the
photograph is a table of contents with an arrow marking where you are.
This table is expandable: click on the folders to open them or close them.
Click on the open book at the top to close it.
Underneath is the text of the current section. When you have read
through it, there are arrows at the bottom to take you on to the next
section or back to the previous one.
Below the photograph are four buttons. Click on expand text to
expand out the whole text of the current section, or book. If the book is
large, this could take a long time and use a lot of memory! Click on
expand contents to expand out the whole table of contents so that
you can see the titles of all chapters and subsections. Click on
detach to make a new browser window for this book. (This is useful
if you want to compare books, or read two at once.) Finally, when you do a
search the words you search for are highlighted. Click on no
highlighting to remove highlighting.
How to search for particular words
From the search page, you make a query in these simple steps:
- Specify what items you want to search
- Say whether you want to search for all or just some of the words
- Type in the words you want to search for
- Click the Begin Search button
When you make a query, the titles of twenty matching documents will be shown.
There is a button at the end to take you on to the next twenty documents. From
there you will find buttons to take you on to the third twenty or back to the
first twenty, and so on. Click the title of any document, or the little button
beside it, to see it.
A maximum of 100 is imposed on the number of
documents returned. You can change this number by clicking the
preferences button at the top of the page.
Scope of queries
In most collections you can choose different indexes to search. For example, there might
be author or title indexes. Or there might be chapter or paragraph indexes. Generally,
the full matching document is returned regardless of which index you search.
If documents are books, they will be opened at the appropriate place.
Two pairs of buttons control the kind of text matching in the searches that
you make. The first set (labeled "case differences") controls whether upper and
lower case must match. The second ("word endings") controls whether to ignore
word endings or not. It is possible to get a large query box, so that you can
easily do paragraph-sized searching. It is surprisingly quick to search for
large amounts of text.
For example, if the buttons ignore case differences and
ignore word endings are selected, the query
will be treated the same as
because the uppercase letter in "African" will be transformed to
lowercase, and the suffixes "n" and "ing" will be removed from
"African" and "building" respectively (also, "s" would be removed from
You can switch to an "advanced" query mode which allows you to combine terms
using AND (&), OR (|), and NOT (!). This allows you to specify more precise
queries. You can turn the search history feature, which shows you your last few
queries. This makes it easy to repeat slightly modified versions of previous
queries. Finally, you can control the number of hits returned, and the
number presented on each screenful.
