The provider I was using to store the documents that were linked from the blog - MediaFire - has purged my account. This is from a combination of me travelling and not responding in time to some claims about copyright infringement they sent me (none of the claims were valid), and them being very excessive in dealing with the situation.
I need to work out how I'm going to resolve it, as reloading all the documents and relinking them will take far too much time to do.
In the meantime, if you need a specific document, please email me and I'll send it to you.
Apologies for any inconvenience.
Geoff
