From the Book's Introduction:
This Players' Rule Book is subject to yearly update. Errors or omissions found between revisions will be notified by issue of an Errata, changes to be included immediately in the working copy (and the revision number updated). This booklet is not meant to be a substitute for any of the White Wolf™ source books, and as such we recommend that players at least purchase and read the relevant clan book. Queries about the interpretation of these rules should first be directed to your Referee or Storyteller who may consult the Admin Council. The latest version of this book and other related UK Masquerade materials (including UKM contact lists, and web links to all domains) is available from the UK Masquerade web site.
