Reddit reviews An Introduction to the Event-Related Potential Technique (A Bradford Book)

An Introduction to the Event Related Potential Technique was (and still is) my go-to source for EEG. It's comprehensive yet very readable and suitable for both beginners and more advanced researchers.

You should read Steve Luck's book. It's a relatively gentle introduction to many of the concepts in EEG and electrophysiology more broadly. I haven't read the second edition, but the first edition is excellent and I imagine the second edition being equally so.

Don't forget Dr. Luck's book: an introduction to the event-related potential technique. It's very accessible and thorough.
