You can obtain textbooks for educational purposes without buying them by checking out the options offered by online textbook rental companies. These companies allow you to rent textbooks for a fee, usually much lower than the cost of purchasing the book outright. Furthermore, many universities offer their own digital bookstore with used and rental textbooks that are typically more cost-effective than new textbooks. There are also online platforms where students can buy and sell used textbooks at a lower price.

There are a few ways to get textbooks without having to purchase them. 

One way is to find open educational resources, such as those from the Open Textbook Initiative, that provide digital versions of the textbooks online for free.

Another option is to look for used books on online marketplaces such as Amazon and ValoreBooks. These sites provide access to affordable, gently-used textbooks that still deliver the same educational value.

Libraries are also a great source for finding free textbooks - both physical and digital. Many universities and college libraries have sections devoted entirely to providing students with access to these resources.

Finally, some professors make their lecture notes available electronically which can serve as an alternative version of a textbook.
