Welcome to PUBMED
I’m going to tell you were I get the majority of my articles. PubMed is an extremely useful site that lets you search tons of articles and researches regarding almost anything that has to do with medicine.
“PubMed lets you search millions of journal citations and abstracts in the fields of medicine, nursing, dentistry, veterinary medicine, the health care system, and preclinical sciences. It includes access to Medline and to citations for selected articles in life science journals not included in MEDLINE. PubMed also provides access to additional relevant Web sites and links to the other NCBI molecular biology resources.”
Many of these articles are not free, meaning that you have to be a scientist to have access to many of the full articles with a subscription to some kind of library but many of them are free. I’m going to write here the basics on how to search this database. For those not lazy and well versed in the Internet a useful tool might be the HELP button that provides basically everything you need to know about PUBMED .

For everyone else I’ll try to write a short tutorial with examples on how to search for free articles in the database.
For example : I want to search free articles in researches and studies regarding obesity . I’ll go to the search tab and write “Obesity” :

The search results will appear . Numerous articles regarding obesity and containing the “obesity” tag . The articles that appear here are not all free articles. You can see a number of 130851 articles containing the “obesity” tags.The articles are organized in pages of 20 articles. You can set the number of articles shown per page. To get the “free full articles” you’ll have to press the Free Full Articles button in the top-right of the page here :

After selecting “Free Full Text” the page containing the free articles containing the “obesity” tags will appear.
Before I show you how to get the full articles I’ll tell you how to search articles by one or several tags. In the search box type for example, if you want articles about Obesity and Sleep, obesity AND sleep. You also have the OR and NOT functions available. When searching for Obesity AND Sleep the articles will appear on the page. Press the Free Full Articles page and the free articles will be shown. Scroll up and down the page or search other pages the article of interest to you and click the highlighted title. After doing this in the top right corner of the page a link to the free article will appear. You can usually downloaded in PDF format to your computer or read it online.

I hope this will help!
