These are the core databases for finding scholarly research articles for your project. If you can't find the information you need, try searching one of the databases listed in the "More Biology/Science Databases" section. For guidance, ask me!
PubMed comprises more than 37 million citations for biomedical literature from MEDLINE, life science journals, and online books. Citations may include links to full-text content from PubMed Central and publisher web sites. MEDLINE (Medical Literature Analysis and Retrieval System Online) is the largest component of PubMed and consists primarily of journal citations; articles indexed with MeSH (Medical Subject Headings) and curated with funding, genetic, chemical and other metadata.
In addition to these resources, data can sometimes be found as supplementary material to an article.
