This is my top recommendation for having on the desk, instead of the real UML standards (thousands of pages). If you're using UML to convey some design (or software construction) information, this book on its third edition provides you simple chapters with only a few pages per UML diagram type, speeding you up in understanding (and allowing you to create new) UML Diagrams.
Our (old) copy of the book
This and the cheat sheet (in the cover pages) makes this book a must have.

From the Back Cover:
Would you like to understand the most important elements of Class diagrams? (See page 35.)(@2016-07-20: Cover photo and co-author)
Do you want to see the new UML 2.0 interaction frame notation for adding control flow to sequence diagrams (see page 58) and the unofficial notation that many prefer? (See page 60.)
Do you want to know what changes have been made to all versions of the UML? (See page 151.)
Do you want a quick reference to the most useful parts of the UML notation? (See the inside covers.)
Do you want to find out what diagram types were added to the UML 2.0 without wading through the spec? (See page 11.)
More than 300,000 developers have benefited from past editions of UML Distilled . This third edition is the best resource for quick, no-nonsense insights into understanding and using UML 2.0 and prior versions of the UML.
Some readers will want to quickly get up to speed with the UML 2.0 and learn the essentials of the UML. Others will use this book as a handy, quick reference to the most common parts of the UML. The author delivers on both of these promises in a short, concise, and focused presentation.
This book describes all the major UML diagram types, what they're used for, and the basic notation involved in creating and deciphering them. These diagrams include class, sequence, object, package, deployment, use case, state machine, activity, communication, composite structure, component, interaction overview, and timing diagrams. The examples are clear and the explanations cut to the fundamental design logic.
If you are like most developers, you don't have time to keep up with all the new innovations in software engineering. This new edition of Fowler's classic work gets you acquainted with some of the best thinking about efficient object-oriented software design using the UML--in a convenient format that will be essential to anyone who designs software professionally.
