Take a brief tour of the Library Discovery Service (LDS) at the video below. The LDS combines the search power of most databases and the library catalogue into one interface and allows you to do comprehensive literature reviews across multiple sources instead of searching databases individually.
If you want to search chemistry and science databases individually, please take a look at the Physics Databases links BELOW.
To search general reference databases individually please see the links BELOW.
