InfoChem offers with the development of SPRESIweb a new dimension in scientific databases integration. Spresiweb combines a large chemical database with lots of links to additonal information sources. The search can be carried out for molecules, reactions and references. Links are provided to SpringerMaterials-The Landolt-Börnstein Database and many suppliers. For a direct document delivery we provide links to CISTI, subito Library Service and to patent offices. The new SPRESIweb 2.12 contains over 5.52 million molecules abstracted from the literature, 4.26 million reactions, 675,000 references and 164,000 patents covering the years 1974 - 2011.
