2. Obtaining a DOI (Digital Object Identifier) for a journal
typically involves a multi-step process that includes the
following:
 Publish Your Journal Article: First and foremost, you
need to have a journal article or content that you want to
assign a DOI to. This content should be published or
accepted for publication in a reputable journal. DOI
registration agencies do not assign DOIs to unpublished or
non-peer-reviewed content.
 Identify a DOI Registration Agency: Determine which
DOI registration agency is appropriate for your journal
article. Different agencies specialize in different types of
content. For academic journal articles, doie and CrossRef is
one of the most widely used DOI registration agencies.

3.  Become a Member or Use a DOI Registration Service:
To register a DOI with doie.org, for example, you generally
need to become a member or use a service provided by a
doie member (often the journal publisher). If you are not
the publisher, work with the publisher or your institution's
librarian to initiate the DOI registration process. If you are
the publisher, you may need to apply for doie membership
through simply sign up process
 Provide Metadata: You will need to provide metadata
(information about your journal article) to the DOI
registration agency. This metadata typically includes
details such as the title, authors, publication date, journal
name, volume, issue, page numbers, and, most
importantly, a URL where the article can be accessed
online. The agency uses this information to create the DOI
link.

4.  Pay Required Fees: These fees cover the cost of
maintaining the DOI infrastructure and services.
Check with the agency for their specific fee structure.
 Use the DOI: After receiving the DOI, you can use it
in your journal article's metadata, citations, and
references. A DOI is typically presented in the form of
a URL, like "https://doie.org/10.xxxx/xxxxxx," and it
serves as a permanent and clickable link to your
article.

5.  Ensure DOI Link Resolution: It's essential to make
sure that the DOI link resolves to the correct article.
Test the link to confirm that it leads to the full-text
version of your journal article.
 Remember that the specific steps and requirements
may vary depending on the DOI registration agency
you choose and any agreements or partnerships your
journal has. Always refer to the guidelines and
procedures provided by the relevant agency and your
publisher, if applicable, for the most accurate and up-
to-date information on DOI registration for your
journal articles.
