ISSN and Bibliographic Data

Bibliographic data of publications in tangible formats which are not categorized as serials (such as monographic series) in the NDL neither contain ISSN in the data nor can publications which do not display their ISSN (by mistake or in the case of back issues which had already been published before the application) be searched for by the ISSN.

Outline of ROAD
ROAD (Directory of Open Access scholarly Resources) (https://road.issn.org/) (opens in another window) is a service provided by the ISSN International Centre with support from UNESCO. In July 2018, ROAD was integrated into the ISSN Portal.
ROAD provides free access to a subset of ISSN bibliographic records for scholarly resources in open access (online journals, conference proceedings, academic repositories, etc.) which have been registered in the ISSN Portal.
The main purposes of ROAD are as follows:
- To provide a single access point to different types of online scholarly resources published worldwide and freely available.
- To provide information about the quality and prominence of OA resources, indicating by which services they are covered.
- To give an overview of the Open Access scholarly production worldwide (for statistics purposes for instance).
- To demonstrate new ways of using the ISSN for compiling information from various sources.
In March 2015, the Japanese National Centre for ISSN started to send bibliographic data to ROAD. Online journals published in Japan with ISSN which meet all the following requirements are registered:
- FREE content permitting any users to read, download, copy, print or link it
- The entirety of their resources are accessible
- Peer-reviewed academic journal
