Shannon's original paper [2] is often touted to be very parseable, but it is always enlightening to read the same basics many times from multiple sources, especially something as foundational as source coding (and broader information theory) in a more modern language.
I also finally discovered the meaning of "differential" in differential entropy [2], the continuous counterpart of discrete probability masses, something that I always swept under the rug.
