Internet Marketplaces explains and analyses the legal questions and challenges posed by the increased use of online auctions and exchanges for business transactions. Rather than focusing on internet businesses as a whole, the author studies the rules related to closed internet marketplaces where commercial dealings are carried out. The book provides a detailed analysis of the new business models that are being employed, their legal structures, and the extent to which further work is still required to fill in the legal infrastructure. Professor Ramberg is well known for her expertise and involvement in this field, and the book will prove to be useful to fellow practitioners as well as being a key reference for academics working in this area.
