What is DOI?
An international, unique and persistent document identifier which guarantees permanent link to a specific electronic document on the Internet. It is assigned based on a membership of the CTU in the Crossref registration agency.
How is the DOI identifier used and what objects is it assigned to
- It provides a permanent link to a full text or a website the full text can be accessed from.
- It is assigned to any type of online document which needs to have a permanent identifier (see more at crossref.org)
- It can be assigned for example to: journal articles, book chapters, conference contributions, contributions in a proceedings, standards, technical reports, theses, dissertations, separate tables, graphs, images, data files etc.
- DOI is assigned to text published as OA as well as texts published as part of a subscription,
- It is used by authors, institutions and publishers together with ORCID author identifier to identify an author and his work.
How does DOI work?
When you click on a DOI link, you will directly get to a full text of an article or a website the full text can be accessed from.
How to cite with DOI?
DOI identifier is used in bibliographic references. Most of the citation styles and citation generators work with DOI.

DOI ASSIGNMENT AT THE CTU
Terms of DOI assignment at the CTU and price
DOI prefix of the CTU is assigned to publications published or co-published by the CTU. It can be used by journal publishers, conference organisers, authors or editors who are interested in having a permanent identifier for a document/content which will be available permanently online (as Open Access or with a link to get the full text in a different way). There is a content fee for every assigned DOI. The fee is paid to the Crossref agency and it is 1 USD for most documents. It is lower for some types of texts (for example book chapters).
The DOI assignment is managed by the CTU Central Library (see the contacts above). It manages registration of newly assigned DOIs and advises publishers who agreed with the library on the DOI assignment and registering the DOIs to the Crossref database.
Metadata of the articles, URL and assigned DOI are sent to the registration agency immediately after publishing the article. The data is then saved in their database, DOI is linked with the URL of the full text/web page leading to the full text and by this permanent conversion of URL - DOI is achieved.
What steps for DOI assignment need to be done on publisher’s/editor’s side:
- Make yourself familiar with the DOI structure (also see tab DOI structure on this page).
- Determine an approximate number of texts/chapters you are planning to publish. The plan is not binding but it is useful for creating an appropriate DOI structure.
- Create the structure of the webpage where the publications will be published. It is appropriate to create a separate landing page for each publication. The landing page should contain at least the following information:
- Names of all authors
- Publication date (year)
- DOI of the publication
- Abstract and keywords
- Link to the full text
- Keep the full texts in the same place. In case of planning of moving them or taking them down you need to consult the CTU Central Library first.
What steps need to be done on the CTU Central LIbrary’s side?
- Agree on the final suffix for the DOI with publisher/editor.
- Import metadata containing DOI to the Crossref database when the full texts are being published - based on information from publisher/editor.
- Update URL-DOI links - based on information from publisher/editor.
If you are interested in having DOI assigned to a publication published by the CTU, read please . There is a summary of basic rules that have to be followed by publishers (see more on the tab Rules for using DOI). If you would like to have DOI assigned, please contact us (see the contact details above).
DOI is an alphanumeric string. It consists of a prefix - assigned to each institution by the registration agency (Crossreff) and a suffix - set by the CTU. It is convenient to have the same basic structure of the suffix for contributions within one journal, conference proceedings, a series or even one institution. Approved characters for DOI are letters of Roman alphabet, numbers, hyphen, period, underscore, semicolon, parentheses, forward slash. Detailed information about syntax of the suffix can be found on the Crossref website.
The CTU is registered as a publisher with the Crossref registration agency and pays annual fees.
- Based on the membership the CTU has been given prefix: 10.14311/
- 10: identifier of the DOI system
- 14311: identifier of the CTU in the DOI system
- Suffix for the CTU (according to a standard practice abroad:
- Abbreviation of the source title (journal, conference).year.volume.article ID (4digits)
- For example for Acta Polytechnica, year 2013. Volume 53 and article starting on page 395 is suffix: AP.2013.53.0395
- The whole DOI then looks like this: 10.14311/AP.2013.53.0395
RULES FOR USING DOI
Obligations given by the CTU’s membership in Crossref
- DOI is assigned during the publishing process. It must be assigned and published together with online publishing of the publication.
- DOI must be written in the document which it is being assigned to.
- DOI must be published on the web page the DOI is referencing to.
- One document cannot have more DOIs assigned.
- DOI assigned to a specific document is not going to change.
- DOI should be always displayed as a hypertext link even if it links to the current page.
- It is necessary to always state DOI of all cited articles in references where DOI is available in a journal which has DOI assigned to its articles
- It is recommended to publish DOI everywhere where the article is cited, or rather in all information about the article.
- The CTU must monitor and keep record if there are any changes of URLs of the articles and the changes must be reported to the registration agency to keep persistence of the DOI identifier. All publishers and editorial boards at the CTU are obliged to keep the link URL - DOI active for all documents.
- Not following the requirements might mean sanctions from Crosref to the CTU. Full requirements and conditions can be viewed here.
