There are a large number of books that have been written on e-commerce, many of which are of varying quality. I have found three useful. The first is by Kalakota and Whinstone (1997). It is an excellent introduction to both the technologies and applications involved in electronic commerce. Kalakota has also written a book on electronic commerce which avoids many of the clichés and which concentrates on unglamorous areas such as supply chain automation (Kalakota, 1999) . If you ignore the jargon and the management speak in this book, you will find it a useful introduction to the way in which computers will affect major economies in the next decade. If you are interested in the economics of e-commerce then a good treatment is a book written by Choi, Stahl and Whinstone (1997). If you wish to delve further into the underpinning technologies of distributed systems then Coulouris et al., (2001) is the best introduction and is an excellent complement to this course. A good introduction to e-business has been written by Timmers (2000).
