Digital Object Identifiers
DOI numbers (Digital Object Identifiers) are unique number combinations assigned to an article. With the help of this DOI number, the article can always be located.
DOI numbers consist of numbers assigned to the publisher (in the example used below these are 10.18831), the journal title ( Journal of Advances in Mechanical Engineering and Science ) and the numbers that define the actual article.
If you have written an article and are looking for the accompanying DOI, you can find it as follows:
In recent articles, especially articles that have been published in an DJRA journal, the DOI number is given at the beginning of the article.
For example, you can find: doi:10.18831/djeng.org/2018011002.
When there is no DOI number in the article, you can check whether a DOI number exists for the article on the Crossref website. A search query on this site gives you the DOI and a persistent link; in this case this is dx.doi.org/10.18831/djeng.org/2018011002.
If this last option does not give you any results, you can copy the address (the URL) of the article from the address bar.
The first step to finding a permanent link to an article is locating it full-text online.
To verify subscribing to the journal, you are trying to link to the electronic format check IJSER Libraries E-Journals.
If you are able to locate a DOI or other permanent link for your article, follow the next steps.
IMPORTANT: It may not be possible to link to the full-text of a journal article online, if the library does not subscribe to the journal or if it is not available for free.
If you have located a full-text article in electronic format and are not able to find its DOI, try the following tool.
Free DOI Lookup: http://www.crossref.org/guestquery/
Complete the form on this Web page with information about the article. Not all fields (text boxes) need to be filled in, but it is recommended to provide: first authors last name; title of the journal (not the title of the article); volume number; beginning page number; year of publication.
If you do not have all this information, enter the citation information you do have. A list of journal titles covered is provided on the above Website. Please note that not all articles have DOIs.
The result of your search, when successful, will be the DOI for your article.
For example entering the following citation information in the DOI Lookup tool: "International Journal of Macro and Nano Physics" : 2456-2483 Retrieved this DOI: https://dx.doi.org/10.18831/djeng.org/2018011002 If this step is successful proceed to STEP 3; otherwise see next step.
If you have located a DOI or other permanent link, follow these steps to complete the link.
To convert a DOI to a URL precede it with the following:
For example: djeng.org/2018011002
