Open textbooks are textbooks funded, issued and licensed for free use, adaptation and distribution.

It is worth noting that public licenses and free digital education resources can be used for education, learning and evaluation free of charge. However, only publicly authorized educational resources are permitted to grant free and unrestricted access and permanent and irrevocable "5R" permission, ie, the creator permits to retain, reuse, modify, redistribute, redistribute . Therefore, all publicly licensed educational resources are free, but not all free resources are officially licensed. (See the table below for a comparison of official educational resources, free digital learning resources, and your own textbooks.)

There is a better way. In 2012, we set up an open and open textbook library - an online catalog of free and authorized university textbooks - and began discussing them with CEHD teachers. The digital version of the textbook can be obtained free of charge or at very low prices. Four years later, the open textbook library had more than 200 textbooks, and it continued to grow rapidly. The success of CEHD attracted interest in several other schools. In 2013, we started to support these schools to create their own open textbooks and to get a lot of money from William and Flora Hewlett Foundations. We organized a seminar to help our teachers be educated and engaged and local staff to help the teachers learn to discuss the textbook options that were held with the teachers. We are pleased that among the professors who participated in our seminar we were able to achieve a recruitment rate of over 40%. In 2015, these schools formed the Open Textbook Network (OTN)
