Online Textbooks in Principles (General)
"The Economy 1.0 is CORE Econ’s original free, open access text for a year long introductory undergraduate course. It includes capstone units devoted to globalization, inequality, the environment, innovation and the networked economy, and the role of government." It was updated for the last time in 2022; subsequent revisions are implemented in The Economy 2.0. The 22-chapter textbook includes a glossary and a set of related videos.
This online textbook is available freely for use by lecturers of introductory economics courses. The first part teaches the basics of economics, while subsequent chapters are of a 'storytelling' nature, applying the concepts to subjects aimed at students' own lives and areas of interest, such as love and marriage, higher education, and crime. The site was taken down in early 2017: this link goes to the Web Archive copy.
