JISC IE and Google
previous paper considered relationships between JISC IE and Google:
complimentary rather than alternative approaches
develop guidance for exposing content to Google
investigate use of Google APIs
special treatment for community’s ‘high-quality’ material – c.f. Google Scholar
encouraging use of OpenURLs by academic and commercial content providers

Conclusions
the study makes 26 suggestions – too many to consider here – but general need to recognise that…
our services are not (and will never be) the sole focus of the end-user’s attention
our services fit into broader fabric of the Internet – therefore need to be able to be integrated by others
some things are better done by others
possible tension between Web-based ‘portal and browser ‘desktop application framework’ approaches
need to align eLeaning and ‘digital library’
