List of Participating STN Databases

The STN Information Keep & Share Program allows STN users to electronically store (archive) and/or redistribute copies of STN search results to co-workers in their worldwide organization. Users may purchase archive and redistribution rights for their organization's needs and then receive the search results by various delivery methods.

Unless stated otherwise, archive allows you to store the search results indefinitely.

Please Note: Each database producer has their own requirements and restrictions for their specific databases that are separate and in addition to the STN Information Keep & Share requirements.
