These books are normally available in Book Centre, Commercial Press and other leading bookstores in Hong Kong. If you could read simplified chiense, you can go to Xin Hua Bookstore in Leighton Road, Causeway Bay where a lot of chinese books on shipping, logistics etc. are available. For English books, you can get it also from Amazon with a lot of varity of issues on Forwarders
