How to find information in the {0} collection

There are 2 ways to find information in this collection:
Changing your preferences

When you click the PREFERENCES button at the top of the page you will be able to change some features of the interface to suit your own requirements.

Collection preferences

Some collections comprise several subcollections, which can be searched independently or together, as one unit. If so, you can select which subcollections to include in your searches on the Preferences page.

Language preferences

Each collection has a default presentation language, but you can switch to a different language if you like. You can also alter the encoding scheme used by Greenstone for output to the browser -- the software chooses sensible defaults, but with some browsers it may be necessary to switch to a different encoding scheme to ensure correct character display. All collections allow you to switch from the standard graphical interface format to a textual one. This is particularly useful for visually impaired users who use large screen fonts or speech synthesizers for output.

Presentation preferences

Depending on the particular collection, there may be several options you can set that control the presentation.

Collections of Web pages allow you to suppress the Greenstone navigation bar at the top of each document page, so that once you have done a search you land at the exact Web page that matches without any Greenstone header. To do another search you will have to use your browser's "back" button. These collections also allow you to suppress Greenstone's warning message when you click a link that takes you out of the digital library collection and on to the Web itself. And in some Web collections you can control whether the links on the search results page take you straight to the actual URL in question, rather than to the digital library's copy of the page.

Search preferences

You can switch to an "advanced" query mode which allows you to combine terms using & (for "and"), | (for "or"), and ! (for "not"), using parentheses for grouping if desired. This allows you to specify more precise queries.

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.

You can turn on 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.
