Fundamentals of Biology Lab Manual
Karen Marks and Valeria Hochman Adler · College Coalinga
Marks and Hochman Adler started developing their OER lab manual for Introduction to Biology when they became frustrated with the paid options and wanted equitable options for their students. Both Marks and Hochman Adler are trailblazers in their field when it comes to accessibility for their students. This lab manual was created in two years with end user testing with students to find what worked and didn't work. This final product is for the students.

Linear Algebra: A First Course
Doli Bambhania, Fatemeh Yarahmadi and Bill Wilson · De Anza College
This book offers a comprehensive and accessible introduction to linear algebra. It begins with methods for solving linear systems, followed by an exploration of matrices and their properties, including a dedicated chapter on determinants. The text then introduces vectors, covering essential concepts such as span, linear independence, subspaces, and linear transformations. From there, it develops spectral theory, including diagonalization and orthogonal diagonalization with their applications.

UTSC First-Year Textbook (Winter 2025)
Marco Zimmer-De Iuliis & Anna Galang · University of Toronto Scarbo
The first-year chemistry curriculum at UTSC covers key principles in general chemistry. In CHMA10, the quantum mechanical model of the atom is examined along with how the periodic table is organized. Students enrolled in CHMA11 and CHMA12 will quantitatively examine reactions and equilibria in chemical systems with an emphasis on their thermodynamic properties and chemical kinetics.

Archaeology: It's More Than Digging In The Dirt
Crystal Scheib · HACC, Central Pennsylvania's Community College
This textbook will help you better understand archaeology and how it acquires knowledge about humans based solely on the material culture of the people being studied. You’ll learn how archaeologists do fieldwork and analyze human behaviors and patterns. Additionally, you’ll see how archaeologists use multiple types of data and evidence to draw conclusions about how humans have lived and adapted to the environment.

Introduction to Genetics
Natasha Ramroop Singh · Thompson Rivers University
Genetics, otherwise known as the Science of Heredity, is the study of biological information, and how this information is stored, replicated, transmitted and used by subsequent generations. The study of genetics can be sub-divided into three main areas: Transmission Genetics, Molecular Genetics, and Population Genetics. In this Introductory text, the focus is on Transmission or Classical Genetics, which deals with the basic principles of heredity and the mechanisms by which traits are passed fro
