Open Textbook for Linear Algebra

WeBWorK problem sets added to a PreTeXt open educational resources linear algebra textbook.

Supported by an Open Educational Resources Faculty Grant at Northwestern (joint with Aaron Greicius), this project added WeBWorK problems to a PreTeXt linear algebra OER textbook, so that the text ships with a bank of auto-graded exercises attached to each section.

Free textbooks are only half the problem; free assessment is the other half.
