3. Collection Development
in physical libraries: users, bibliographers, jobbers determine and carry out policy
elicit patron input (explicit vs implicit)
citation
analyses
usage
analyses
trade recommendations/reviews and peer reviews
constraints: mission, space, $, time
two extreme points of view: severe curation vs vacuum everything
is there a thematic scope?
Active acquisition vs passive acceptance
Ownership/responsibility vs openness
Quality vs usability
Manual vs automatic acquisition
Quality and trust
Khoo paper: DLESE as library and as digital artifacts; peer review models (simple two tier operation)
Bergmark paper: can we automatically build DLs by crawling the web?
How is collection synthesis like/unlike book jobbers?
Do you agree that collections of 20-50 good documents are best? (how different than a result set?)
Procedure: for a topic, select a set of documents using search engine, compute centroid, use terms in centroid for focused crawls (document similarity [threshold] and path depth [cutoff] used to truncate crawls)
Compare to our automatic classification of a given DL/website
4. Digitization
‘resolution’ and compression issues
what does it really mean to go from ‘analog’ to ‘digital’?
See Stoa http://www.stoa.org/guides/ for guides to photography/images, GPS coding, QTVR etc
