    • The US based National Center for Infectious Diseases has produced a treasure trove of publications and resources that will be of great help to travellers and their healthcare providers ( From details about cholera infected countries to a database of the sanitation inspections of international cruise ships (including a list of ships with unsatisfactory scores), there is a mass of information here. This is an amazing collection that should be a core reference point for global travel medical advice.

    • From the Scottish Intercollegiate Guidelines Network ( comes a well designed site with downloadable documents on a range of subjects, from day case cataract surgery to the control of pain in people with cancer.

It is also possibly therapeutic for the authors. Certainly for doctors it is an illuminating read.

    • For a useful compendium of sites relating to evidence based practice and systematic review, have a look at Many of the sites mentioned are well known already but it is useful to be able to access them all from one page. Helpfully each link is accompanied by a description and, although the host site looks at cardiac rehabilitation (worth a look in its own right), the resources on this page are of a general nature.

    We welcome suggestions for websites to be included in future Netlines. Readers should contact Harry Brown at the above email address
