Other material existed before PPS happened, and has been very kindly "donated" by the authors. Besides this, the beauty of the WWW is of course that any URL is "a click away", and there are many excellent and useful sites that are not directly related to the course which we will recommend that you examine.
However, that certainly doesnt mean to say that other sites won't ever be highly relevant to the course. The explosion in Web resources means that it can be difficult to keep up with whats available relating to a particular subject. So you will probably at some time stumble across a very useful URL which we dont know about; in which case tell everyone by using the Discussion Lists. So it will be worth occasionally putting time aside to have a good wander round the Web if you can.
Sometimes we will make a link to just one or two particular sections of a whole library of resources, for example a chapter of a "Hypertextbook". We will try and be as specific as possible about which parts we are referencing in each chapter of the course.
In summary, it will be worth being aware of when you are looking at course material served from Birkbeck Crystallography Department, and when you are somewhere remote to Birkbeck, so that you can easily navigate back to the course pages; keep the "Location" or "URL" displayed on your Web-Browser.
