Check CLIO to see which library has your journal. A few are in Biology Library (Fairchild). Those looking at physiology and behavior may be in Psychology (Schermerhorn). Journals of nutrition and sports medicine may be in Teachers College library.

The journals you are looking for are probably in the Health Sciences library uptown. You can get there by shuttle bus, find the journal, and make a copy of the article. Uses different copicard, so best to bring pocketful of change. Check CLIO first to see if journal title is there AND if your particular issue is there. Very new issues may not have arrived yet; some older issues may be in the bindery, which takes the recent issues and binds them into the hardcover volumes.

Many articles are now online, but finding them can be tricky. For example, I just tried to find an article that appeared in Pediatrics:

• At the journal's website www.pediatrics.org you're asked to pay for access to the journal.
• At Columbia's libraries page, I went to e-journals, and found the issue, but the page I wanted was not included.
• At Columbia's libraries page, I went to databases, then Medline, and searched for the article by author or topic. I got a link to the abstract, but not the full article.
• At the PubMed site http://www.ncbi.nlm.nih.gov/entrez/ I searched for my article by author or topic. This time, when I got the abstract, there was a link at the top of the page which took me directly to the full text of the particular article I needed.
