- Further Information
CAS is committed to the global advancement of science through the dissemination of scientific information to promote research performed by individuals and teams of scientists. Daily, hundreds of CAS scientists read scientific journal and patent literature and thoroughly analyze and index the information so that it can be consistently and easily found in the CAS Databases, thereby enabling scientific research.
CAS is aware of the changing needs of researchers who rely on scientific information to perform their daily tasks. With the advances in technology, the wealth of information available to scientists, and the race to new scientific breakthroughs, scientists must be able to find and use scientific information with more ease and flexibility.
Relying on the CAS Information Use Policies, CAS provides this ease and flexibility. Customers will find that CAS permits the building of Project directories/files and the sharing of information among team members for the life of the Project. CAS permits the sharing (but not aggregating or searching) of information globally within an organization even with those who are not team members. To support Data Mining, CAS permits the extraction of Metadata for use within CAS or STN® provided tools without first displaying the data. The use of CAS data in third party Data Mining Tools is permitted as long as CAS Records are downloaded via STN® AnaVist™. All of these new "freedoms" are aimed at further enabling the dissemination of scientific information and the advancement of scientific research.
CAS Information Use Policies are aimed at supporting scientific research performed by individuals and teams of scientists, while protecting the business structure CAS is built upon. These Policies are not aimed at providing a mechanism to aggregate CAS information and offer it globally within an organization for use by all. CAS does not permit the building of Databases that have wide and general availability and no longer fulfill the purpose of individual or team research that CAS permits but instead serve as a substitute for the use of CAS Databases.
CAS Information Use Policies
These Policies apply to all forms of CAS information unless the licenses for CAS products provide otherwise. These Policies are subject to change at the discretion of CAS.
CAS information is copyrighted by the American Chemical Society (ACS). All rights reserved. CAS' mission is to be the world leader in disseminating chemical and related scientific information.
These Policies define appropriate and inappropriate uses of information and apply to all forms of distribution (printed, electronic, CD, and other media). These Policies are meant to be read in their entirety, not taken individually out of the context of the other points. Search results delivered in computer-readable form remain the property of CAS. Recipient shall obtain CAS' specific written permission for any uses of computer-readable search results other than those listed under Authorized Use of CAS Information.
These Policies apply to scientists, engineers, librarians, information professionals, and others working in their organization that either search and retrieve information or ultimately consume the information. They do not apply to vendors of CAS licensed databases, marketing agents, gateway service operators, web search operators, publishers, software developers, or other commercial redistributors of information, whose use of this information must be covered by separate agreements.
ACS does not make any warranties, express or implied, regarding CAS information. In the event errors should appear, please report such to CAS Customer Care.
For the purposes of these Policies, the following terms will be used as defined below:
