This is a presentation I gave at the Library of Congress as part of a NFAIS/FLICC/CENDI meeting as outlined here: http://www.chemspider.com/blog/making-the-web-work-for-science-presentation-at-the-library-of-congress.html The presentation provides an overview of some of the challenges the publishers face moving forward, how they are responding to it, how InChI is an enabling technology, how quality is important.
