* Biology: Home

Once you have a good understanding of your topic and have selected a few keywords, LibrarySearch is a great place to start your research! LibrarySearch is a convenient way to search almost all of the library’s resources using a single search box. 

Below are a few of the "top" journals in biology by the number of times their articles have been cited. To see many more journals in biology, including sub-specializations, see our Journals by Title page and select "Health and Biological Sciences" from the subject drop-down.

Below are just a few of our databases useful for biology research. For more databases with biological sciences content, check out our Databases A-Z page and select "Biology" from the drop-down.

LibrarySearch is the combined library catalog for the entire University of Maine system. You can search the entire system, or select University of Southern Maine Libraries in the drop-down.

Other helpful tips:

• If you find a book that is relevant to your needs, look at the "Subject" area of the book's record. Click on a few of the subjects to find other similar books.
• If the UMaine System doesn't have a book you want, we can get it for you through Interlibrary Loan (ILLiad).

Most databases, as well as LibrarySearch and MaineCat, assign subjects to books and articles. A subject is a designated word or phrase that describes an idea or concept and groups all articles or books about that concept together.

• Subjects are also variously called descriptors, controlled vocabulary, headings, or index terms.
• To search by subject you have to know the exact subject term. Most databases that use subjects have a Thesaurus that you can use to look up subject terms. You can also do a keyword search, find a book or article that is relevant to your research, and look at the subject terms assigned to it.
• LibrarySearch and MaineCat use Library of Congress Subject Headings and each database has their own list of subject headings, so you have to look up subjects in each database independently.

There are many ways you can get research materials from other libraries. In the vast majority of cases, there is no charge to you for this service!
