These databases are the best bets for finding articles on genetics, developmental biology, and evolutionary biology.

Browsing both current and archived issues of scholarly journals can be helpful too.  Some relevant sources:

• BMC Developmental Biology
• BMC Evolutionary Biology
• Human Genetics

Finding the best articles on your topic requires these steps.

• Select an appropriate database.
• Enter and combine terms appropriate to your topic
• Scan the best items on the results list and look for new subject terms or keywords. Then revise your search using these new terms.
• Save the journal title, volume, date, and page numbers.  This is all part of the "citation". 
• Explore other databases and subject terms (which vary between databases) for more information.

Once you find the citation, try the   button to see if Penn State has the electronic or print version of the article you need. If the electronic version is available, it will appear as the first link on the Get it! menu. If the article is not available electronically, click on The CAT link to automatically search our catalog and see if Penn State has a print copy. If no other copy is available, you use the InterLibrary Loan (ILL) link to request it from another library.  ILL will get a copy of the article for you, typically at no cost; articles usually arrive within a week, often in as few as 2-3 days.
