Zetoc provides access to the British Library’s Electronic Table of Contents (ZETOC Alert) and is one of the world’s most comprehensive research databases, giving access to over 28,000 journals (of which over 21,500 are current), 45 million article citations and conference papers.
Available at: http://zetoc.mimas.ac.uk (you will need to login if off-site).
A new enhanced Zetoc service is expected to replace the current version on Tuesday 15 November 2011, including an enhanced interface and additional abstracts (coverage starts in 1993, rather than 1999).
Your Alerts will be unaffected, but access to Zetoc Alerts will be frozen from Monday 14 November until the implementation of the enhanced service is complete on the 15 November.
You can preview the Zetoc service in beta version at: http://beta.zetoc.mimas.ac.uk/
