What is a DOI?
"DOI" stands for Digital Object Identifier. It identifies an article, book, or other resource with a permanent and unique combination of numbers and letters. Example: 10.4103/0976-500X.110897
DOI searches can be performed by pasting or typing the DOI into the library catalog search box.
If you have problems accessing any online resource, check out our FAQs where you can also submit your question to the library: http://libanswers.esf.edu.
If you find an article and can't get the full text, you can always request an interlibrary loan.
