29 Joint JIIE/JCS MeetingConclusions 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’ Joint JIIE/JCS Meeting
