Search Engine
• Xapian (free search API) boolean text search + post-sorting
• Rank-by:– Boolean search score– Citations (Paper, Author)– Dates (Repository datestamps…)– Downloads [UK arXiv only]– ‘Hub/Authority’ (Google PageRank?)

www Interface
• Metadata display– Getting UTF-8 right is tough
• Full-text links (+limited PDF-linking)
• Navigation by author, citation, co-citation
• Citation/Download history
• Citebase Citations/Downloads

Analysis Tools
• Papers over time/by field
• Citations over time (by field)
• Citation “latency” (read-write-cite latency)
• Usage (downloads) by country
• Correlation (“predictiveness”) between downloads/cites

Perspective of a Service
• IRs serve an institutional need
• Services can be built on IRs to serve community’s needs
• Communities need:– Access to the primary literature *full-text*– Means of discovery (is Google good enough?)
– Development of new services & ideas … competition at the point of use
