Setting up a My NCBI Account with the OutSide Tool
My NCBI is a service offered by PubMed where users can create accounts to save searches and results, be alerted with new results for saved searches and link directly to the Ames Library Print and Electronic Journal Holdings. You will still have to login into the Proxy Server if accessing electronic journals off campus.
