However, if you are willing to invest in publications it may be the best way of obtaining them. You can always try to contact publishers yourself. In many cases the name of the publisher and one or more cities where they have their offices are given through this bibliography. International telephone enquiries should be able to give telephone or fax numbers from these details. Their full addresses will also often be available through specialist book stores and main libraries who will probably hold copies of the directories of publishing services.
Some publishers hold copies of their most recent editions, sometimes small stocks of older ones.
At the very least they should be able to direct you to their distributor or a dealer who may still have stock. This is mostly relevant to the purchase of books. Journals and other publications are often less accessible but are still reasonably easy to obtain for the first two or three years after they appear. Whereas book publishers are rarely willing to make copies of texts, journal and magazine publishing houses sometimes carry off-prints of individual articles and essays or will make copies for you. You may be required to pay small charges for post and packing, occasionally for off- prints or copies.
