The Standard Code of Parliamentary Procedure is understandable, comprehensive, logical, refined, and efficient. As it should, it covers all the formal business of holding a productive and respectful meeting. But it also includes procedures that facilitate business for the less formal organization or club.
Necessary jargon is defined in a glossary. The "Often-Asked Questions" section covers many common situations and eliminates the need to look through the chapters for most answers. The book is up-to-date, addressing contemporary and often-encountered situations such as holding meetings and elections via the telephone or Internet.
As a bonus, it serves as a resource to those trying to form an organization. There are chapters to help you prepare documents (like bylaws and financial records) that won't be in conflict with legal and parliamentary procedures down the line. It explains the hierarchy of documents that govern an organization. There's even a section that helps explain some of the arcane procedures in Robert's Rules!
I'm grateful to have found this gem. It deals with all the situations that my clubs have encountered.
