For the class exercise, the focus has been on Medline (via Web of Science). There is another variety of Medline that you can access via "PubMed".
The latter is a freely accessible database, but if you use the link on the library's database finder, you can see the Lehigh Links. For a comparison of the various flavors of Medline, and for an overview of the details about using Medical Subject Headers, contact the science librarian.
Google Scholar is a great source of bibliographic information. Look for the advanced search engine. Make sure Lehigh Links is turned on, per the instructions below.
Make sure you restrict your searches to scholarly articles in below two databases:
If you have an article reference, this video tutorial shows how to use Google Scholar to quickly access it and otherwise order a copy of it. (Google Scholar has of course many other uses as well, see Google Scholar: Understanding Scholar.) The tutorial discusses "Lehigh Links" to access the article if available and otherwise use ILLiad to order it. Make sure you have Lehigh Links turned on from within Google Scholar.
You may also want to download the Google Scholar Browser extension available here, so that you don't have to look up Google Scholar but instead have it readily available right in your browser.
In library databases, you will see "Lehigh Links", which enable you to get out to the full text,of articles or order an article that is not available electronically. This brief tutorial video explains how to use Lehigh Links. NOTE: for books, you will see a link to the online catalog ASA, so that you can look up a book or ebook. You will also see a link to ILLiad so you can order the print version of a book if Lehigh does not have it.
