Three-Year Interim Reporthttp://imlsdcc.grainger.uiuc.edu/
2003 – 109 respondents, 76% response rate
2006 – 72 respondents, 72% response rate, with 26% panel mortality
* p-value of chi-square .05 or below. Odds ratios measures, significant finding has confidence interval that does not contain 1.
Among 169 collections:
Top ranked subject headings: one kind of view
Top ranked subject headings: better landscape view
increase from 84% in 2003 (n=94)
increase from 59%
increase from 65%
But most only have anecdotal evidence of user base. Some beginning to study use.
Similar increase in all types, except interactive resources more pronounced (institutions responding in 2003 & 2006)
Surveys provided important, but crude benchmarks.
Other data sources add important details, raise many questions.
Influence of content management systems – deterring use of MODS and TEI encoding decisions - (interviews)
Need models for description of newer, more complex and interactive objects, such as works of art / art “events” - (case study)
Fundamental questions remain:
What is lost or changed in the process of federating “collections” or items accumulated for a purpose -- to “explore” “demonstrate” “provide insight into” … ? - (collection descriptions)
How build and retain “contextual mass” (Palmer, 2004), in light of 88% scholarly audience
