# Welcome to the Free ECE Textbook Initiative

**Why Free Books?**

Very simple answer: Over the past 30 years, the consumer price index (CPI) increased by 270%. Over the same time period, textbook prices increased by 1000%, almost a four-fold increase compared to CPI.

**$ Savings For Students**

Since its inception in August of 2018, textbooks published by the Free Electrical and Computer Engineering Textbook Initiative have been adopted by over 500 U.S. colleges and universities, and have saved students an estimated $40 million in textbook costs.
