Scientific literature, especially journal articles, can be accessed through the library's collection of databases. Databases are structured collections of items so you will need to search in a more structured way compared to searching using web search engines. This also allows you to search deeply for very specific topics.
You may want to start by searching more broadly before a more advanced database search. Try searching using the "Articles" search in the library catalog. This is a good option for when you are beginning your search and need to do some initial searching to see what has already been published on your topic/question.
For a more advanced and deeper search of the literature, search in subject-specific databases. The databases that contain literature related to biology are listed below.
Another way to search for information is by journal title. Below is a selected list of journals that publish on biology.
In addition to the library's subscription databases. This is a list of biology-related open-access databases.
Biology
Botany
Zoology
Google Scholar is a useful way to do a broad search and see what's available on your topic. However, it doesn't directly provide access to the full-text of articles, and you will often hit paywalls.
It's possible to configure Google Scholar so that you can use it to search, but then use the Library's databases to access full text when it's available. You'll see a "Get It @ Bradley" link to the right of your results when this option is available. The handout linked below shows the steps to set this up in Google Scholar.
