Please note: Not all indexes and electronic journals allow persistent links to be made. Also persistent links are not truly persistent. This is because database providers, which will give access to journals of many publishers (ex: EBSCO), sometimes remove full-text access to journals from their databases.
For more information view the general overview of the database linking process.
