Wikileaks just seems a slightly odd place to be directed. I was meaning if there was a central database maintained by some official body. Is this technically private data somebody published?

If you do not want to download and read that version of the document for an explanation then you could go through the process of accessing a more recent version via

https://dtg.org.uk/the-d-book/

Or another alternative is to gain a role in a company that will enable access for you.

That’s kind of what I wondered, whether it was commercial information or open. Thanks that makes it much clearer.
