Precalculus
Jay Abramson · OpenStax
This precalculus textmap is intended for college-level Precalculus students and is a comprehensive book that covers more ground than an instructor could likely cover in a typical one- or two-semester course; but instructors should find, almost without fail, that the topics they wish to include in their syllabus are covered in the text.

Our World Ocean: Understanding the Most Important Ecosystem on Earth
W. Sean Chamberlin, Nicki Shaw, and Martha Rich · Fullerton College
This book offers an alternative to the traditional, dry-as-bones, hohum approach of the standard textbook. Sure, it covers all the topics you’ll find in a traditional oceanography textbook. But that’s just the tip of the iceberg. We go broader and deeper. We write the way people talk— conversationally. We encourage folks to interact with the text, to click through to full-size images, to view video and hear audio, and to quickly access the reference materials.

Principles of Strategic Management
Precha Thavikulwat · Towson University
This book is meant to complement a course in strategic management composed primarily of a simulation game and cases. The book is distinctive in its coverage of strategy implementation from a psychologist's point of view. Coverage of strategy formulation is basic, to encourage students to invest time and effort in the game and cases. Even so, this book neither includes nor recommends any particular game, nor does it include or recommend a particular set of cases.
