Lochrie's "Meeting Procedures" is a good alternative to Roberts Rules of Order Newly Revised (RONR). Both of these books are intended to be adopted by organizations as the parliamentary authority, but no matter what authority you use, "Meeting Procedures" is a valuable addition to the presiding officers bookshelf.
Where RONR has pages of rules for special cases (which ~do~ come up), Lochrie takes a different approach. A group using "Meeting Procedures" will find special rules are easier to adopt (2/3 vote, no notice), so that special cases can be handled by individual groups with special rules as they are required, allowing the book to be more streamlined. For example, there are no rules in this book on disciplinary procedures (trials). These things (thankfully) rarely come up, and an organization using Lochrie's book could adopt special rules for the proceedings when and if they do.
Elections, something that does come up, is thoroughly covered, including detailed examples. Also covered is the interesting subject of "election paradoxes", and how to cope with them with various voting methods (e.g. the Borda count).
Included with the book are a section with answers to some common parliamentary questions, sample minutes, a sample committee report and sample convention rules. One thing that seems to be missing is a sample set of bylaws, but one can find such things on the internet (with varying degrees of quality though!).
Overall, a wonderful book, even if your group prefers RONR or another authority.
