UKPMC and Supplementary material
• UKPMC holds around 1.7 million full text articles
• Around 90,000 documents have supplementary material
– Equates to over 277GB of data
– Around 200,000 files, predominantly PDF’s and MS Word files, but also
13,000 MOV files, 18,000 TIFF files
• Currently supplementary information is not searchable, nor curated
– i.e. no characterisation of files; no preservation strategy
• MIMAS doing a small-scale study to look at whether a tool like
Autonomy could provide some form of access to these objects
– Vic Lyte will talk to this
Use of Supplementary Material
• 01 January through 31st March 2010
– 696,221 unique user sessions at UKPMC, who downloaded 2,218,743
papers
– 130 downloads of “Supplementary Material”, from 47 documents.
• PMC2612414 – SI data downloaded 19 times (Figures and tables – PDF
format))
• PMC2262892 – SI data downloaded 15 times (Molecule structures – PDF
format)
– Low usage may, in part, be a reflection of the fact that these objects are
not indexed and searchable
• Higher usage at PMC
– On the DOCSUM page – around Click Through Rate (CTR) 0.5%
– On Full text views – CTR around 8% (55000 full text documents viewed
4200 views to Suppl. Material
Questions/clarifications/Issues
• Overall, keen to listen to, and participate in, these discussions
• If Dryad-UK does go ahead, we would fully support establishment of
appropriate links with UKPMC to maximise access to data
– NCBI have been asked to consider offering a service to allow NIH
grantees to upload supplementary data. This would be accessible
through the PubMed record (and PMC if the full-text was in this
repository)
– NCBI would not curate the data
• Costs?
– UKPMC costs WT around £500k a year – equal to around 0.1% of
research spend
– Any idea what Dryad-UK might cost?
