SciFinder is now also available on the web. The traditional downloadable “client” version will continue to be available, but will be phased out over the next 6-10 months.
Follow the instructions to register for the web version.
The MIT Libraries subscription allows a total of eleven (11) simultaneous users between the web (one-time registration required) and the client versions. Those 11 “seats” have been divided between the two versions. If one version reports that all seats are taken, please try again later or try the other version.
