NS 1220: Nutrition and the Life Cycle: Finding scholarly literature

Types of scholarly literature

You will encounter many types of articles and it is important to distinguish between these different categories of scholarly literature.  Keep in mind the following definitions.

Peer-reviewed (or refereed):  Refers to articles that have undergone a rigorous review process, often including revisions to the original manuscript, by peers in their discipline, before publication in a scholarly journal.  This can include empirical studies, review articles, meta-analyses among others.

Empirical study (or primary article):  An empirical study is one that aims to gain new knowledge on a topic through direct or indirect observation and research.  These include quantitative or qualitative data and analysis. In science, an empirical article will often include the following sections:  Introduction, Methods, Results, and Discussion.

Review article:  In the scientific literature, this is a type of article that provides a synthesis of existing research on a particular topic.  These are useful when you want to get an idea of a body of research that you are not yet familiar with.  It differs from a systematic review in that it does not aim to capture ALL of the research on a particular topic.

Systematic review:  This is a methodical and thorough literature review focused on a particular research question.  It's aim is to identify and synthesize all of the scholarly research on a particular topic in an unbiased, reproducible way to provide evidence for practice and policy-making.  It may involve a meta-analysis (see below). 

Meta-analysis:  This is a type of research study that combines or contrasts data from different independent studies in a new analysis in order to strengthen the understanding of a particular topic.  There are many methods, some complex, applied to performing this type of analysis.

 

Finding Full-Text Articles

Use the Get it! Cornell links wherever you see them!

If you have citations for specific articles, check the Library Catalog to see if we subscribe to the journal that contains the article. The Catalog will show whether or not we have access to the electronic version and/or the print version. Note that this catalog also searches WorldCat, a database of library holdings from around the world.  So if the Cornell library collection doesn't have what you're looking for, this catalog will tell you who does, and link you to Borrow Direct or Interlibrary Loan options (see below).

If we don't have it, we can get it for you for free in a few days! Request materials through Borrow Direct or Interlibrary Loan by clicking the Request Item button.

Reference librarians are here to help you - so please contact us with any questions!

Off-Campus Access to Full-Text

If you're off-campus and want access to full-text, you can either go to the resource via the library website or use the hand PASSKEY tool. Using either method, you will be prompted to log in with your netID and password to gain access to our licensed resources.

Key databases for nutrition and health literature

Searching Databases

Boolean SearchingMost databases allow the use of AND, OR and NOT to broaden or narrow and search. 

  • AND will narrow the search to include only records with both terms. 
  • OR with broaden the search to include records with either term.
  • NOT will narrow the search to exclude records with one of the terms.

Truncation:  You can use an * at the end of a word stem to broaden your search to include related terms.  For example, to search for child, children or childhood use the search term child*

Putting quotes "" around words allows you to search for a phrase.  For example, searching language development, without quotes, finds records with both the word 'language' and 'development' somewhere in the record.  Searching "language development", with quotes, only find records with the phrase "language development".

 

Example: How does bilingualism affect language development in children?

 

 

NOTE:  When you begin doing advanced searching in a new database, look for the Help or Information sections to determine how that database works, and how it may differ from other databases with which you are familiar.

The value of citation searching

An excellent way of discovering new and relevant resources is to use the articles that you have already identified as important works in you search.  The articles and resources in the references or bibliography can point you to other relevant sources that were published prior to the article of interest. 

But how do you find more recent articles that have used and cited the article of interest in their work?

 

Web of Science is a database of scholarly literature that also tracks citations and allows citation searching.  In the search results window you can:
