I Need a Few Good Articles, Please!

First, get your subject in mind, like "Could obesity be caused by a virus?" This is the most important step (and the hardest)

Next, try the world's biggest health sciences database, called PubMed. Do an Advanced (click it) search; input obesity, click ADD input viruses, click ADD & click Search. Refine the results on the left of the Results page by year (last 5 years) full text, language, ages, controlled clinical trials or whatever you prefer to find a few good articles.

Click Send to and send to your RefWorks account to help design a beautiful References list to attach to your great paper.

PubMed Searching Management

Getting Published Info

Locate great places to publish at Ulrich's Periodicals Database. You can input a subject like functional foods and find a list of authoritative, peer-reviewed journals and information about how you can get published with them.

At you can find information on open access publishing, including the Repository @ TWU.. You can learn more about open access at the Directory of Open Access Journals (see at Creative Commons (at and at resources like SPARCalid.

Please be careful. It can be difficult to identify valid, peer-reviewed, authoritative journals in the mass of a business model that has publication offers popping up constantly in your email. Many appeals to the potential author appear, on the surface, to be scholarly, valid research organs of communication, but careful research reveals that the appeals are actually something else. Please ask your librarian for help or do the research yourself.


To determine if an offer to be published is the kind of high quality journal you seek, library scientists have produced some helpful resources. Take the title and any other information you have about the title and start your search. Trust, but verify.

Look Local

Look for local county or parishes to find statical data on information, sometimes down to the block level.  You can find data similar to 'the number of white women aged 18-30 who gave birth in X year" this way.  Look for local charity organizations (United Way, America's Charities, etc.) to find more data.
