Low gravitational pull?Little social dynamic

‘Monolithic fragmentation’‘Monolithic fragmentation’

• Move to ‘concentrate’ at local level • Single search environments

• Move to ‘diffuse’ at local level• RSS, APIs, ….

• But …• Have to manage presence at the local, group and global level

GroupGroup

Data?• Knowledge base• Aggregate usage data

• Resolver data• Download data• Database usage data• Circulation• …

• Shared catalogue (eg OhioLink)

• Syndicate to global (eg Google Scholar and union catalogues)

• Switch to local for fulfilment

Applications?• Repository? (eg HAL)• Search

• Institutional search (Primo, WC Local, etc)

• Metasearch• Catalogue

• LMS?• Network effects: e.g.

circulation and recommendation

• Shared selection• CIRC <> resource sharing

GroupGroup

The collective collection?

• Competition for space and ongoing cost a concern

• Legacy print collections (cf UKRR) • Storage• Preservation• Access

• Physical delivery architecture

The collective collection?

• Managing a licensed collection• Ebooks• Journals• Preservation• Access models

Where data aggregation is beneficialWhere data aggregation is beneficial

• More effective exposure in a web-scale site (metadata)

• To attract users and social engagement

• Avoid redundant data management (supplier details, supplier suggestions)

• Collective knowledge - tasks less complicated or more accurate (serial prediction)

• New knowledge via deduction or mining (eg holdings count indicating rareness and popularity, supplier performance, enriched name metadata)

• Most effective management of links and imported enriched data

• Comparison of collections; facilitating the management of the collective collection

GlobalGlobal

• Discovery• Registry (of institutions, services, collections)• Electronic delivery architecture

LocalLocal

• Interpretation of specific research and learning needs of institution

• Intersection of research/learning and information management

• Reputation management• Disclosure to group and global levels• Funding

““There’s an illusion being created that There’s an illusion being created that all the world’s knowledge is on the all the world’s knowledge is on the web, but we haven’t begun to glimpse web, but we haven’t begun to glimpse what is out there in local archives and what is out there in local archives and libraries. libraries. Material that is not Material that is not digitized risks being neglected as it digitized risks being neglected as it would not have been in the past, would not have been in the past, virtually lost to the great majority of virtually lost to the great majority of potential userspotential users.”.” - Ed Ayers - Ed Ayers

Change in Photoduplication PolicyAs of March 17, 2008, the Ransom Center's policy regarding research copies of items from its collections will change. We will no longer furnish photocopies. For all requests received on or after March 17, our default procedure will be to make digital scans of the originals and furnish PDF files (72 dpi) either by email or on CD-ROM. For patrons who are unable to make use of PDFs, printouts will be available in lieu of digital files.For publication purposes, high-resolution images will still be furnished on the same terms as before.

Benefits of concentrationBenefits of concentration

• Search results ranking• Holdings data• Usage data (eg display, circulation)

• Recommendations of related books• User contributed content can be shared

• User contributed content can be made better

• Attention can be attracted and redirected

Benefit of concentration:ranking based on numberof holding libraries

Benefit of concentration:More data to mine

Benefit of concentration:ability to make user-contributed data better

Benefits of diffusionBenefits of diffusion

• Library holdings syndicated into places where people are found (eg Google)

• Small libraries can play in big spaces (the ‘long tail’)

• The more paths there are, the easier it is for people to reach you

Put things under people’s nosesPut things under people’s noses
