Vade Mecum

A vade mecum is a handy reference guide or manual kept for quick consultation. The term, originating from Latin meaning "go with me," typically refers to a compact book that summarizes essential information on a specific subject, such as medicine, law, or mechanics. It's designed to be portable and easily accessible, helping professionals or students quickly find key facts or procedures without having to consult larger, more detailed texts. Essentially, it serves as a reliable, condensed resource to support decision-making and efficient work in various fields.
