If you find an Open Textbook you want to use for your class, you can adopt it. You can simply provide the link in Nexus and all your students will be able to access it. If you do adopt a textbook, let Campus Manitoba know — it helps with the long term viability of the project to know there has been uptake!
Because Open Textbooks are openly licensed, you can also adapt a textbook - you can update it, localize it, add or remove content, and more. Follow the Adaptation Guide from Pressbooks to learn more, or check out 6 Easy Steps to Modifying a Textbook from BC Campus.
Regardless of platform, there are a couple of basics to presenting and organizing content you should keep in mind.
The most common platform for hosting OER in Canada is Pressbooks, but some people use GitHub as well. If you are interested in using Pressbooks to create a professional textbook, please contact Brianne Selman.
Images you find "on the internet" are usually copyrighted, which means that you need to be careful about how you reuse them. However, there is an ever growing amount of images that have been made available with Creative Commons licenses, or other licenses that allow reuse. If you are going to use these images, familiarize yourself with the license types - CC-By, for example, just requires attribution of the creator, but CC-SA requires that anything that reuses that work also be licensed with the same Creative Commons license.
The following resources are excellent for finding images that allow some reuse:
In addition to open images, Creative Commons has a very good list of open/ re-usable resources you can use when creating an OER (or for other educational purposes).
There are many sites listed on these pages that are used to find OER. Most allow for direct submission of OERs.
When submitting your OER, the metadata (the information about the resources) are important in aiding discoverability. You will want to include as much information as possible in these submissions, including thoughtful keywords/ subject headings, and descriptions that include not just descriptions of the content, but also the audiences/ uses a work is applicable for.
If you want help promoting your OER, UWinnipeg Library has a form that you can fill out as a precursor to discussion with Brianne Selman, Scholarly Communications & Copyright Librarian.
