Mendeley is a reference manager that allows you to create a personal database of references related to your research, and it allows you to insert citation into Word using any one of hundreds of citation styles. If you are collaborating with other researchers, Mendeley allows you to share references.
There is a free version of Mendeley that anyone can sign up for. However, MSU faculty, staff, and students have access to Mendeley Institutional Edition, which provides more stoarge space for PDFs and more functionality.
Note from Mendeley Support: "As a result of supporting High Sierra, Mendeley Desktop will no longer be able to support OS X Mavericks (OS X 10.9.5 and below). Automatic update notifications for users on OS X 10.9.5 and below will be switched off, users will remain on Desktop 1.17.13 and won't be able to upgrade ... Please note that any bugs or issues encountered on OS X Mavericks won't be fixed."
To access the Institutional Edition of Mendeley, be sure to register with your MSU email address. If you already have a Mendeley account, you can simply change the email address in your account settings.
Once you access Mendeley on the MSU campus network or using the MSU VPN (Virtual Private Network), you should get access to the Institutional Edition.
Use the Mendeley Desktop to build and organize your collection of references and documents, which you can sync with the web and mobile versions. Drag & drop PDF files into the Desktop to instantly create references. Annotate PDFs with highlights and sticky notes as you read them.
