Apparently I’m not the only person who has seen a need for an open textbook for introductory physical geology. BCcampus has just released one, and I was lucky enough to get in at the tail end of the process and add a chapter on the origin of Earth and the solar system.
In case you haven’t heard of open before, these are resources which are free to use, and are available with non-restrictive or minimally restrictive licenses, or released to the public domain. This particular book has a CC-BY license. That means anyone can use the book in any way they please, so long as they give the creator appropriate credit, and note whether any changes have been made. Quite simply, it’s a free textbook.
A lot of work went into this book, and that is evident when you look through it. The author, Steven Earle, not only explained a wide range of topics in an enthusiastic and conversational style, but he also drew or adapted a great many figures. From my own experience, I can tell you that figure drawing takes up a lot more time than the actual writing. (But then again, I’m the sort to vacillate between shadow settings or tweak a font for 5 to 10 minutes before I’m happy with it.)
This textbook has a special focus on the geology of British Columbia. That’s a Canadian focus that many commercially available physical geology textbooks have lacked until recently, judging by the regular shipment of freebies I get from the textbook companies.
The textbook is not only accessible as an online resource, but it can also be downloaded in a variety of electronic formats- you could put it on an e-reader, for example.
The online version of the book is built in Pressbooks, and I was immediately enamored of the aesthetics and ease of navigation… so much so I got my own Pressbooks account for experimentation. I’m finding it a bit slow, however my internet signal fails on really windy days (one of the perils of a rural home office), so maybe it’s not their fault.
The one feature of this textbook which has had the greatest impact on me is the fact that I can edit it- all by my lonesome, no permission required. In its current form, the book presents some of the topics differently than I do in my course, so I inquired about making the changes. The result? Amanda, a lovely lady from BCcampus, emailed me the latest version of the XML file, and I imported it into my Pressbooks account. It was that easy. (The XML file is one of the download options as well.)
I was pleasantly surprised at how straightforward it was to get something I could edit, but what surprised me most of all was the immense sense of relief I felt when I discovered that there were no barriers to making the textbook fit my needs. I’ve always been a bit of a control freak when it comes to my course materials- on a bad day that translates to downright resentment at not being able to fix things that need fixing- but I had no idea that I was so stressed out about not being able to control my textbooks.
