DIGITAL OBJECT IDENTIFIER (DOI) AND CONTRACT WITH CROSSREF

Digital Object Identifier:
— Assigned to scientific articles and collections
— An address that never changes (i.e., immune to: migration to a new online platform, website restructuring, change of publication owner)
— A standard adopted by all leading publishers (400 publishers)
— A constantly growing range of capabilities
— 12 thousand journals using the standard
— 16.8 million registered identifiers
— 10 thousand new DOIs daily
— 90 million user requests to DOI per year (3 requests per second)
— A constantly growing range of capabilities

A DOI may include various information, for example, the article’s URL (Uniform Resource Locator), article title, author, publication information, and other metadata, which you must carefully fill in and double-check when adding articles and collections for placement in the Russian Parasitological Journal (RPJ) and others.

Attention!
Without a Digital Object Identifier (DOI), neither your articles nor your collections will ever be included in scientometric databases such as Scopus and Web of Science!

A DOI consists of a prefix and a suffix and has the following form:

«10» — identifier indicator — always remains unchanged

«15421» — unique digital designation of the publisher. Each publisher (e.g., publishing house, individual institution, individual person) must have its own unique designation (prefix), which can be obtained from one of the official DOI registration agencies or from third parties who have a valid contract with these agencies.

«abc1234567890» — (suffix) — the actual identifier of a specific object, e.g., a scientific article or collection. The suffix must also be unique — duplicates are excluded. The suffix may contain both numbers and letters, as well as individual characters.

As practice shows, publishers tend to use their own special principle for constructing the suffix, for example, including the journal name (or abbreviation), journal ISSN, issue number, article sequence number in the collection, publication date, etc. The presence of this scheme is especially relevant for journals that may publish hundreds of issues and thousands of articles.

A DOI is assigned to:
— Journals, journal issues and volumes, journal articles
— Book series, books, individual chapters/sections
— Conference proceedings, individual reports
— Tables, figures, graphs in books/articles
— Dissertations, database records (soon)

Examples of DOIs:

To assign DOIs to articles and issues of your scientific journal, you need to take several sequential steps:

1. Enter into a contract with CrossRef for DOI registration or contact third parties who have a valid contract with these agencies;
2. Obtain and assign a separate DOI to each scientific article and issue;
3. Regularly pay annual membership fees to the agency, as well as invoices for DOI registration.
4. Transfer metadata of all your online publications along with their URLs to CrossRef, register DOIs for them using the obtained prefix
5. Transfer metadata of articles cited in your publications to CrossRef
6. Set up external links based on the obtained DOIs of cited articles
