I have been inspired by the following books and tutorials throughout the time I have spent learning programming languages. These books very much shape my perspective on the course, though none entirely overlaps. If I had to pick just one, I would strongly recommend you read EOPL at some point.

• Essentials of Programming Languages, EOPL
• Structure and Interpretation of Computer Programs, SICP
• LISP in Small Pieces
• How to Design Programs, HtDP
• Programming and Programming Languages, PAPL
• Mitchell, Theories of Programming Languages
• Matt Might’s blog
