What is DOI?

Digital Object Identifier, in short DOI, is a unique alphanumeric string assigned to a digital item by The International DOI Foundation. The publisher will assign an DOI for every resource published electronically, such as eBooks and eJournals. DOI provides a persistent link that will direct you to where the content is available online, ensuring that the content is always accessible. Hence, even if the URL to an article changes, we can locate it effortlessly through the DOI. 

Example of a DOI: https://doi.org/10.1007/s00127-007-0262-4
