When I was writing the Log Book, I referred to a large number of online resources. Rather than expecting you to type in all the links by hand, I've included a list here. Please note that these links are for the second edition. However, there are no links in the first edition that do not appear in the second as well - so you should be able to find what you're looking for below. If you're looking for any amendments or errata click here. All other links open in a new window.
