A reminder about copyright
Before any attempts are made to use or adapt an Open Textbook, care must be taken to understand the copyright and licensing issues.
Carefully read and note the information in this section before progressing any further into your exploration of Open Textbooks.
Copyright is a form of legal protection, automatically provided to authors of original creative works (literature, images, music, etc.).
This is important, because:
if your search for an Open Textbook involves any desire to find and alter a textbook in any way (reproduce, upload, remix, etc) without consideration of the copyright status of the work (and without checking that it has a license that enables you to make these changes) you may be operating illegally under the copyright protection afforded to the author.

In the next column, you will learn about Creative Commons licenses, and how they facilitate the Open Textbook movement - enabling you to enjoy a number of freedoms (with author approval) to use, adapt and remix the publications of others.
Creative Commons (aka CC) is a licensing system that enables authors to personally select the terms under which their work may be copied, modified, remixed or adapted. CC provides authors with a range of licence types, each of them offering potential users of the works a set of conditions by which they must abide. CC licensing provides the user of another person's work with freedoms that are not available to them under Copyright.
The table (below) indicates the properties of the CC-BY 4.0 (Attribution) license. It shows you exactly what the license allows you to do with the material you have chosen.
The CC-BY-4.0 licence allows you to:
Share: copy and redistribute the material in any medium or format
Adapt: remix, transform, and build upon the material for any purpose, even commercially
You are required to observe the following terms:
Attribution: give appropriate credit, provide a link to the licence, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
Attribution: The information in this section of the Open Textbooks LibGuide ("CC Licences") has been adapted and modified under the provisions of CC-BY 4.0 (Attribution). The creator of the original image is Piotrek Chuchla, "OERs and Open Licenses - Open American" licensed under CC-BY 3.0. (an earlier version of CC-BY 4.0 (Attribution).
Are Open Textbooks really "free"?
Not only are Open Textbooks cost "free", but are also "free" of many of the restrictions of copyright, thanks to the generosity of their creators who share their works by assigning CC licences to them. However, depending on the CC licence, they may come with restrictions.
Your task, as an explorer of potentially useful Open Textbooks, is to ensure that you fully understand the licensing systems, and diligently check your chosen text to ascertain if the licence attached to it provides you with the freedoms that you want.
