How can we link to OPAC?

Users can set links between CiNii and their OPACs by using NCID, ISSN, ISBN.

*This function is for only for institutions using the institutions authentication. Administrators can set it from the settings page for institutions.
For more details, see "About the OpenURL Sending Function".

Libraries connected to the online cataloging system (NACSIS-CAT) are able to set and display a link to their OPACs on CiNii Books by adding the data to information on connected library of NACSIS-CAT database, if their OPAC can receive NCID as a parameter.
