What's Included in a Need to Know eBook

BrainMass "Need to Know" eBooks provide you with study-ready explanations of key concepts and ideas. Our books are authored by our Experts, who are also available to answer questions. Here's a quick rundown of what each of our academic eBooks features:

A Useful Introduction to the Concept

Each Expert takes the time to explain the nature of the concept, where it comes from and why it's relevant for those studying that subject. Often, a real-world example of why it's important is included. Our introductions "set the stage" for you to read on and learn everything you "need to know."

Key Points in their own Sections

Each "Need to Know" eBook will be broken down into a few different sections. Each individual section will be dedicated to one aspect of the book's topic, which when put together, will ensure you have a full understanding of the topic at hand.

Diagrams & Illustrations

Many of our Experts will include illustrations and visual aids to enhance their eBooks. Often, having a diagram can really help in making something easy to understand, so we encourage our authors to use them as much as they can.
