In case you have missed it, its important we all nowadays know what colour our favourite publisher is. Find out at http://www.mulita.indiana.edu/Librarians/colorcoding.html. Its important because the trend towards self (or institutional) archiving is growing apace, and the type of archive is characterised by its colour. Thus good = Gold. not bad = Green, pale green etc. Typical is eg http://www.dspace.cam.ac.uk/handle/1810/740 being the Dspace archive at Cambridge. Out of interest, is there anyone on this list who has or itends to archive their own work in chemistry? -- Henry Rzepa. +44 (020) 7594 5774 (Voice); +44 (0870) 132 3747 (eFax); rzepahs@mac.com (iChat) http://www.ch.ic.ac.uk/rzepa/ Dept.
