Bookmarking articles for future visits
Even though this site uses frames, every page can now be bookmarked (or made a 'favorite') by following the procedure normally adopted with the browser of your choice. If you find we have missed one, please contact us.
Printing the text of an article
The printer icon is linked to a printable version of the article which omits the notes and thumbnail pictures. The omitted pictures are listed at the end of the article and each of these can be printed in the normal way.
Viewing hyperlinks and images
When words are underlined, or are differently coloured—as
are the words 'contact us' in the paragraph above—they are almost always hyperlinks leading to other parts of the site or, less frequently, to other sites.
To speed downloading, images in the text are thumbnail versions. A hand icon appears when the mouse is passed over; clicking over the thumbnail usually leads to a larger, clearer version, with acknowledgements to the source of the image and, often, to an extended caption or additional notes.
Always return from these full-screen versions by clicking the browser's back arrow.
