I thought i had solved this problem, but somehow it reappears:
We have delayed open access and use the subscription module
We don't ask unsubscribed users to register
Unsubscribed and unregistered users are allowed to view open access pdf's
As long as an issue is not open access, only users with a subscription can view the subscribed PDF's. Subscribers either log in or are recognized by IP-adress.
This translated in the following setting in the set up menu and issue data:
checked: Allow users to register with the journal site as: readers
checked: Unregistered users can view the journal site.
checked: Unregistered users can view the full text of published articles.
checked: The journal will require subscriptions to access some or all of its contents.
Access status: Subscription
Open access date November 01 2007
Now it appears that non-subscribers can view PDF's from the issue wich has the open access date set to november 01 2007.
You can try it by accessign the current issue mentioned: http://library.wur.nl/ojs/index.php/njas/issue/current
My question whether there is a conflict between the policy settings and subscription settings?
