Dear Penny, There are others better qualified than me on lis-maps to answer your enquiry, but as you haven't got a reply for a couple of days, I thought I'd give a quick answer. The World Directory of Map Collections, KG Saur, 1993 - IFLA Publications 63 - indicates classification schemes in use in larger map and spatial data libraries around the world. For evaluative details of map and spatial data classification schemes, I'd recommend: Mary Larsgaard. Map Librarianship : an introduction. 3rd ed. 1998. Earlier editions also useful Harold Nichols. Map Librarianship. 2nd ed., Bingley, 1982. A more British perspective, much of it still relevant. A detailed guide to other references can be found in Mary Larsgaard's Chapter 17 Cataloguing and classification, in CR Perkins and RB Parry's Information Sources in Cartography, Bowker Saur, 1990. Hope this is of some help to start with. Christopher Fleet Map Library National Library of Scotland 33 Salisbury Place Edinburgh, EH9 1SL United Kingdom Tel. 0131 466 3813 Fax. 0131 466 3812 E-mail.
