a reference and guidebook, such as about Robert's Rules of Order

• Perhaps best read by first reading the Table of Contents and other front and back matter, and surveying the structure of the book.
• Then consider the purpose of the reading, what you need to know (everything, or general familiarity then use as reference, or just a quick introduction).
• So far, this helps to see what tools to use to look up material later to get more details, or which parts to read first.
• Then read or skim relevant & important parts accordingly, and either make notes or mental notes on what else is there for future use if/as needed.
