Agriculture Research Guide: Articles with DOI numbers

This is a general guide to finding information on agricultural subjects including crops, soils, forages, farm management, agricultural and biosystems engineering, and sustainable agriculture (SARE).


Using the DOI to locate an article

The new edition of the APA style manual endorses the use of DOIs to help locate material.  Note the DOI at the end of the article citation:

Lerner, R. M., von Eye, A., Lerner, J. V., & Lewin-Bizan, S. (2009). Exploring the foundations and functions of adolescent thriving within the 4-H study of positive youth development: A view of the issues. Journal of Applied Developmental Psychology, 30(5), 567-570. doi:10.1016/j.appdev.2009.07.002

DOI stands for Digital Object Identifier.  It is a system that provides a persistent URL (web address) for documents on the Internet.  Publishers must register a DOI for articles.  The system is pretty new, so some publishers will use it and others may not.

There are several ways to locate an article using the DOI:

  • Type the address into your browser, starting with, as in
  • Go to the DOI system link resolver page and use their lookup service []
  • Google the entire DOI phrase "doi:10.1016/j.appdev.2009.07.002"

You will then be taken to the webpage for the article on the publisher's website.

Important!  The full-text of the article will only be available if the publisher recognizes that you are an MSU student and if we have a subscription to the journal. 

To be recognized as an MSU student, you will need to have authenticated through the proxy server by logging on to any MSU Libraries subscription resource.  You can also add the phrase "" to the beginning of the DOI link (e.g. to force the proxy server login page.  However, if MSU does not have a subscription to the journal the full-text will not be available.  Use the library catalog to check to see if we subscribe to a particular journal.
