Recommended databases and interfaces (ie aggregators)
Researchers want authoritative and accurate sources of information in peer-reviewed or otherwise scholarly publications. The best way to find these types of publications is through a database not a search engine.
Discovery Tools (to begin with):
INSPIRE by subject (try Health & Medicine and STEAM; example keyword "natural selection")
BASE (Bielefeld Academic Search Engine) a search engine for finding scholarly or academic articles
More focused/in depth:
AGRICOLA covers research agricultural science (e.g. hybridization, entomology, pesticide resistance, etc.)
Public Library of Science (PLoS) (an open access publisher)
PubMed database of life sciences related research articles maintained by the US National Library of Medicine
NCBI (National Center for Biotechnology)
General Research & Reference:
Science.gov all kinds of information here from various US government science and medical agencies
Other useful tools:
WorldCat find books and journal titles in several thousand libraries
DOI (Digital Object Identifier) use this indexing number system to find your article across a variety of databases
Keywords for evolution research
Think like a thesaurus when you are getting started on something you know little to nothing about. It might take you some time to figure out the terminology being used by the experts in the field.
For evolution try: evolution, natural selection, speciation, species, adaptation, mutation, uniformitarianism, selection pressure, allele frequency
For smarter, easier researching...
TIP: Pre-filter your search. Use the filtering and refinement tools to limit or focus your search before you begin.
For instance, if you want to make sure the book (or article- this applies to them, too) is about your subject, use a title field search. Usually, the search tool you are using will have a dropdown menu from which you can select "title" to search for your keyword or keywords in the title fields of the records.
TIP: Just because it does not say BIOLOGY doesn’t mean it is not relevant to what you are doing. Do not neglect a source because it does not seem to match your topic. For example, another subject area that might apply to biology research would be Health.
