Some publishers only allow institutions to archive the pre-published version, From time to time, the Library receives authors' feedback that they prefer users to read the published version rather than the pre-published version archived in the IR. One can easily resolve this problem by adding the direct URL link to point users to the published version residing on an aggregator's or the publisher's website to which the institution has a subscription. The Library objected to this approach because such links would become broken due to subscription changes. After much study, the Library decided to implement an OpenURL linking mechanism on DSpace so that users can be dynamically redirected to library-subscribed resources that host the published version.
