Link Structure and Information Storage
The current versions of each pattern description have Internet addresses (URLs) which are structured hierarchically so, for example, the URL for section (6.4.1), Overview of Pressures on Politicians, is https://www.patternsofpower.org/patterns/political/pressures/overview/.
Each pattern description begins by stating which version it is. Some current versions have had the benefit of additional thought, experience and refreshed Internet links since the last published edition of the books. If citing them, though, it must be remembered that the material is liable to change – so links to an archived version might be preferred.
Archived copies of each version are retained for as long as possible, particularly where these have been quoted in one of the published books. These are in separate directories, not structured hierarchically, with URLs that reflect the section numbering – such as https://www.patternsofpower.org/edition02/641.htm for section 6.4.1 Overview of Pressures on Politicians in the book Patterns of Power: Edition 2. Later editions are in separate directories as appropriate.
Interim versions of some patterns will also be archived – for example where these have been incorporated in a blog entry. They will be in separate directories, with URLs in the format https://www.patternsofpower.org/version02a/3433.htm for example.
Version 02a represents an update on edition 02. It is, of course, possible that version 02a might not be further changed in edition 03 when that is published.
