This book has been produced primarily as a work for undergraduate students of commercial law. “Commercial Law” is a topic which means many things to many people. No two degree courses are identical in coverage. Many books have appeared under this and similar titles over the years, but few have the same content. The authors of any book on the subject, therefore, start from the disadvantage of having to define their scope and to justify it. This the authors of this work do admirably. I believe their selection to be a good one. As they say, all courses of this type concentrate on sale as the paradigm commercial transaction and then there is a tendency to deal with one or more of a range of other topics as suits the lecturer of the day. At various times my own course has included agency, bailment, negotiable instruments and insurance.
