Standards are a basic tool of scientists and engineers. At Rodgers Library we use SAI Global to find and order individual standards. SAI Global covers standards from many standards organizations, such as ASME and SAE. Our approach is to order most standards on demand. However, since ASTM standards are in high demand, we recently subscribed to ASTM Compass. In the case of SAI Global users can easily search the database, but the library takes care of the download piece. ASTM Compass is handled differently. It is delivered to desktops and users can search and download independently.
