"Covers all of the topics in a typical first course in differential calculus. Initially it focuses on using calculus as a problem solving tool (in conjunction with analytic geometry and trigonometry) by exploiting an informal understanding of differentials (infinitesimals). As much as possible large, interesting, and important historical problems (the motion of falling bodies and trajectories, the shape of hanging chains, the Witch of Agnesi) are used to develop key ideas. Only after skill with the computational tools of calculus has been developed is the question of rigor seriously broached. At that point, the foundational ideas (limits, continuity) are developed to replace infinitesimals, first intuitively then rigorously." Organized into 16 chapters, with additional appendices.

- Active Calculus Multivariable (OER textbook)Steve Schlicker, David Austin, and Matthew Boelkins, Grand Valley State University, revised ed., 2018. “Active Calculus Multivariable is the continuation of Active Calculus to multivariable functions. The Active Calculus texts are different from most existing calculus texts in at least the following ways: the texts are free for download by students and instructors in .pdf format; in the electronic format, graphics are in full color and there are live html links to java applets; the texts are open source, and interested instructors can gain access to the original source files upon request; the style of the texts requires students to be active learners — there are very few worked examples in the texts, with there instead being 3-4 activities per section that engage students in connecting ideas, solving problems, and developing understanding of key calculus concepts; each section begins with motivating questions, a brief introduction, and a preview activity, all of which are designed to be read and completed prior to class; the exercises are few in number and challenging in nature.” This textbook is also included on the American Institute of Mathematics (AIM) site for approved textbooks for Calculus. HTML and PDF formats, also provides link to LaTeX files on GitHub. CC BY SA (Creative Commons - Attribution - ShareAlike) license. Eligible for Print on Demand.
- APEX Calculus (OER textbook series)Gregory Harman, Virginia Military Institute, et al, 2014 (Version 5 updated 2022). “This text comprises a three–text series on Calculus. [...] The third text covers topics common in “Calc 3” or “multivariable calc:” parametric equations, polar coordinates, vector–valued functions, and functions of more than one variable, found in Chapters 9 through 14.” This textbook is also included on the American Institute of Mathematics (AIM) site for approved textbooks for Calculus. PDFs in color and in black & white. Also provides link to source files via GitHub. CC BY NC (Creative Commons - Attribution - NonCommercial) license. Eligible for Print on Demand.
- Armstrong Calculus (OER textbook)Michael Tiemeyer and Jared Schlieper, University System of Georgia, 2015. “This text is an adaptation of two very excellent open-source textbooks: Active Calculus by Dr. Matt Boelkins and APEX Calculus by Drs. Gregory Hartman, Brian Heinold, Troy Siemers, Dimplekumar Chalishajar, and Jennifer Bowen. Topics include integrals, volume, arcs, density, physics applications, differential equations, and hyperbolic functions.” Includes preview activities, activities, exercises and problems for each chapter (8 chapters in total). Online, Word (editable), Accessible PDF, EPUB, and source files via GitHub. CC BY NC SA (Creative Commons - Attribution - NonCommercial - ShareAlike) license. Eligible for Print on Demand.
- CLP Calculus (OER textbook)Joel Feldman, Andrew Rechnitzer, and Elyser Yeager, University of British Columbia, 2018. “Written by faculty at the University of British Columbia and used there for several years, the four volumes cover the full calculus sequence for science and engineering students. The exercises in each section are grouped into three stages [...] Stage 3 exercises are more challenging and may require combining more than one idea, incorporate review material, or ask the student to apply a concept to a new situation.” Vol. 3 is Multivariable Calculus, and Vol. 4 is Vector Calculus. This textbook is also included on the American Institute of Mathematics (AIM) site for approved textbooks for Calculus. PDF textbook, PDF problem book, HTML and PDF combined textbook with exercises, and source files via GitHub. CC BY NC SA (Creative Commons - Attribution - NonCommercial - ShareAlike) license.

- Multivariable Calculus (OER textbook)Don Shimamoto, Swarthmore College, 2019 (last updated 2022). “This book covers the standard material for a one-semester course in multivariable calculus. The topics include curves, differentiability and partial derivatives, multiple integrals, vector fields, line and surface integrals, and the theorems of Green, Stokes, and Gauss. Roughly speaking the book is organized into three main parts corresponding to the type of function being studied: vector-valued functions of one variable, real-valued functions of many variables, and finally the general case of vector-valued functions of many variables. As is always the case, the most productive way for students to learn is by doing problems, and the book is written to get to the exercises as quickly as possible.” Site includes faculty peer reviews of this text. PDF via Google Drive; includes a PDF option formatted for printing. CC BY (Creative Commons Attribution) license.
- Vector Calculus (OER textbook)Michael Corral, Schoolcraft College, 2013 (last updated 2021). “This is a text on elementary multivariable calculus, designed for students who have completed courses in single-variable calculus. The traditional topics are covered: basic vector algebra; lines, planes and surfaces; vector-valued functions; functions of 2 or 3 variables; partial derivatives; optimization; multiple integrals; line and surface integrals.” PDF, low-cost hardcop, LaTeX files.

- 3D Interactive Plots for Multivariate Calculus (OER textbook)Dr. Na Yu, Toronto Metropolitan University (Canada), 2022. “An open textbook created to improve both teaching and learning vital concepts and techniques in multivariable calculus, one of the fundamental courses across the undergraduate curriculum in science and engineering. The goals of this resource are to help learners develop their geometric intuition about abstract and complex mathematical concepts (e.g., partial derivatives, multiple integrals, vector fields), and train them to make connections between concepts visually (e.g., connecting “vectors” in mathematics with “magnitude” and “direction” in physics) in order to more fully understand engineering, physics and mathematical problems (e.g., differential equations) in their subsequent STEM coursework.” Each unit is structured into “the concept” and “the plot” with interactive self-check questions/activities.
