13. • All parties would benefit from support of standard APIs
and data representations in order to enable TDM across
both open access and subscription-based publishers.
• Subscription-based publishers find it impractical to
negotiate multiple bilateral agreements with thousands
of researchers and institutions in order to authorize TDM
of subscribed content.
• Researchers find it impractical to negotiate multiple
bilateral agreements with hundreds of subscriptionbased publishers in order to authorize TDM of subscribed
content.

32. We are using CrossRef's Prospect text mining API in the context
of the Hiberlink project, which investigates reference rot in
scholarly papers at a very large scale. The API is really
straightforward and based on common technical approaches; it
can easily be integrated in a broader workflow. In our case, we
have a work bench that monitors newly published papers,
obtains their XML version via the API, extracts all HTTP URIs, and
then crawls and archives the referenced content. Currently, we
can only access Elsevier papers via the API but as more
publishers join Prospect, it will become a powerful, uniform onestop-shop for text mining scholarly literature.
--Martin Klein and Herbert Van de Sompel, Los Alamos National
Laboratory

33. I think this is a big step in the right direction and makes
retrieving full text file a lot easier, I hope that publishers support
it.
