Can I set links from OPACs at a library ?

Yes, you can.
There are several ways to link. Linking directly to Book & Journal Details Page using NCID or linking to URL of search results using OpenURL.

In case of direct link using NCID, please use URL of
https://ci.nii.ac.jp/ncid/<NCID>
ex:
https://ci.nii.ac.jp/ncid/BN03306104

For more details, see "About the OpenURL Receiving Function for CiNii Books ".
