If you want a hard copy, search in DiscoverE. If the library does not have the journal you need, you can request it from interlibrary loan or an electronic copy via Illiad (login with your Emory ID and then click "copy of article" on the left). If the journal you need says it is in "storage," you can request the item from the WHSC library and they will notify you when it is ready.
If you want an electronic copy of a journal article:
Go to eJournals and search for the name of the journal. If the name of the journal you need is available, a link will appear. Click on the link to see what options are available for finding the article electronically. If your journal is not listed, or if Emory does not currently have access to it, you may request it via Illiad(login with your Emory ID and then click "copy of article" on the left).
