Textbook: The recommended textbook is Peskin & Shroeder, "An Introduction to Quantum Field Theory." It was written from a modern point of view and is probably most widely used textbook on this subject nowadays, so it's a nice book to have. However, we will not follow  this book exactly. We will start with a brief introduction on Relativistic Quantum Mechanics. The standard textbook for this subject is Bjorken and Drell, ``Relativistic Quantum Mechanics.'' However, it contains materials much more than one can cover for a whole quarter. We will only have time to learn the basic ideas of the Klein-Gordon and Dirac equations. You can download the brief lecture notes here:
A Brief Introduction to Relativistic Quantum Mechanics
Other useful books are ``Advanced Quantum Mechanics'' by Sakurai and ``Intermediate Quantum Mechanics'' by Bethe and Jackiw. There are also many useful free notes on the web which you can find with Google. After discussing its limitation we will move into the subject of this 230 course sequence "Quantum Field Theory." We will follow very closely to Prof. Gunion's lecture notes. You can find them at
http://higgs.ucdavis.edu/gunion/QFT-I.pdf and
http://higgs.ucdavis.edu/gunion/QFT-II.pdf.
The lecture notes are very well written and allow a smooth connection to 230BC for the next 2 quarters. The 230A part of the lecture notes are close to the Quantum Field Theory book by Mandl and Shaw, which is one of the easiest field theory book to read, but the notes use more modern and better coventions and notations. You probably don't need to buy this book as all useful information is covered in the notes. The materials covered in 230A roughly correspond to the first four (or five) chapters of Peskin & Schroeder's book. There are also many other quantum field theory books on the market with different approaches and emphases. It is a big and difficult subject and you won't be able to learn everything from a single book and neither can we cover everthing in one year of the course sequence. In order to have a deeper and broader understanding of this subject, you should not be satisfied with what you learn in the classes and should keep on learning by yourself even after finishing the course sequence, especially for the students who plan to do theory researches.

There are also many useful resources which you can find on the web. In particular, the videos of the classic lectures on Quantum Field Theory by the late Prof. Sidney Coleman of Harvard University are online:

Grading: There will be homework assignments every week. Doing the problem sets is an extremely important part of learning. You can't learn the subject by just listening to the lectures without working through things by yourself. You can discuss the problem sets with your classmates, but you are not allowed to copy other people's homework. Each of you is required to write up your own homework following your own understandings. Each problem set is due about one week after its assignment in class. The solutions will be given on MyUCDavis course website immediately after the class on the due day and hence no late homework can be accepted. (So even if you couldn't finish you should turn in what you have done.) The homework will count 50% of the final grade. There will be a take-home final exam. You have to work on your own and are not allowed to discuss with other people for the final exam. The final exam will count 50% of your final grade.
