Journal Citation Reports
Take a look at the Journal Citation Reports and see which journals rank high in your field. At the same time, you also need to consider which journals can help you increase your research impact.
A DOI is a unique and persistent identification number for the digital object with which it is associated. DOIs are commonly assigned to online scientific articles. Many journals now require DOIs to be included in references. More about DOI.
Go to the DOI Resolver page, type in the DOI string and click on "Submit". If you are on campus, the DOI Resolver will take you to the "Find it at GSU" page. This page not only shows you the citation of the article, but also shows you if we have the article electronically or in print. If we don't have it in either form, an ILL link will show up so you can request it through Interlibrary Loan.
Go to the CrossRef Simple Text Query page, paste your reference in the box provided and click on "Submit". It will provide the DOIs if available.
Note: Some articles don't have a DOI.
