What is a DOI?
Answer
A DOI or Digital Object Identifier is a string of numbers and letters that identifies a published journal article and sometimes a book and provides a persistent link to the source online. All DOI numbers begin with the number 10.
DOI numbers can take various forms. Here are a few examples:
Traditional DOI starting with 10: 10.1371/journal.pone.0028816
DOI embedded into Marist Library URL: http://dx.doi.org.online.library.marist.edu/10.1371/journal.pone.0028816
DOI embedded into URL: https://doi.org/10.7589/2019-01-012
All are correct format for use in citations, you do not have to convert them so they all start with 10.
