Confession time: I only read this book because it was ~80 pages and counted for bookrace 2013. All I can say is that I'm very glad that semiotics exist, because like Baudrillard's Disneyland, it is the nonsense that makes my discipline real.
I honestly thought this was by Sebeok, himself. I found the text hard to read and dry, simply summarizing all the studies Sebeok had performed in his life, though I'm intrigued to read some of his work.
Originally a Festschrift for Sebeok's 80th birthday this is a concise and very interesting introduction to his work. It made me want to read all of his books.
