This is a list of sources for material and chemical properties and data available at the University of Maryland Libraries by subscription. Much of this information will not be picked up by search engines, so these sources are the best place to begin your search.

SciFinder-n You must first create an account using your @umd.edu email address to use the web version. Unlimited simultaneous users. To use off-campus, sign into the GlobalProtect VPN and change the gateway setting to TunnelAll. SciFinder-n is published by the Chemical Abstracts Service (CAS) and gives you access to current high-quality scientific information in chemistry and related sciences. Content at a Glance: searching MEDLINE and Chemical Abstracts (CAPLUS) individually or at the same time; more than 15 million reactions; more than 1 billion predicted property values; more than 2 million experimental properties; the CAS REGISTRY database is updated daily; patent records from the major patent offices are available online within 2 days of the patents' issuance; sequences combined from CAS and GenBank databases, which are indexed and linked to scientific journal and patent literature.
Reaxys Reaxys is a web-based platform based on three chemical information databases: (Former) CrossFire Beilstein, (Former) CrossFire Gmelin and the Patent Chemistry Database (PCD). In addition, Reaxys is an extensive repository of experimentally validated data, including structures, reactions (including multi-step reactions) and physical properties. It also contains pharmacological, eco-toxicological and toxicological data, specific bioassay results, logPs, toxicity values, and other valuable data. Reaxys allows searching for substances by chemical name or by structure, as well as for single and multi-step reactions. Searches can also be performed for citations, which are indexed from the primary organic, inorganic and organometallic chemistry journal literature going back to 1772, as well as from the patent literature.
