Sustaining Digital Scholarship

• Collecting scholarly projects into a curated collection

• Creating large-scale scholarly projects since 1992• Graduate students have been heavily involved• Dissertations and theses will become much more

complex

Digital Scholarly Projects

• These are not articles nor illustrated monographs• They generally represent the scale of effort of writing

a book • These projects are more like virtual exhibitions than

like books• Scholarly commentary is interwoven with elaborate

linking among resources

The Rossetti Project

• Started in 1992 by Jerome McGann• Intended to be a model for digital critical archives

that combine critical and facsimile editions• An edition of all of Rossetti’s written and graphic

works• ~5,000 XML files, ~12,000 image files• Involves many different rights agreements

Assumptions

• The primary assumption is that we are bringing the projects into the Library’s management stream

• They often include large numbers of digital surrogates of traditional resources

• Increasingly, they will include born digital primary resources

Some policy implications

• The collection of digital projects should go through the selection process

• The Library must be prepared to enforce appropriate access control policies

• We must make explicit promises to authors• The Library will probably have to define these

promises as levels of effort

The Future

• Collecting project that are created in the wild is not scalable

• An authoring environment that supports the creation of very complex projects

• Projects created into an institutional repository directly

• Move to digital library upon selection
