Atanu Garai poses an interesting question. Essentially, I believe he is asking why the industry is pursuing institutional repositories when subject-matter repositories and consortial repositories may have greater upside. Discipline-based approaches should resonate with the researchers, as their first loyalty is to the field. Consortial-approaches should resonate with the sponsoring bodies, as they distribute costs. Why, then, have institutional repositories initiatives have gotten the lion's share of attention/money/effort/publicity? Primarily because they are far easier to get up and running. Repository advocates within a single school should have a good sense of their institution's idiosyncratic bureaucracy and decision-making structure. They are also likely to have a basic understanding of how to secure the resources (funds, staffing, hardware, etc.) to get an IR launched. Extrapolating that knowledge beyond the school's boundaries is a challenge. Who does what work to support a discipline-based repository? How are expenses fairly distributed among the partners of a consortial approach? In either instance, how is the free-rider problem minimized? This is but a quick observation on the subject. There are obvious examples of both subject-matter (obligatory arXiv reference here) and consortial (CDL) successes. The bottom line, however, is that launching an IR is a more straightforward and capturable task for most institutions. -- Greg Tananbaum Consulting Services at the Intersection of Technology, Content, & Academia (510) 295-7504 gtananbaum@gmail.com http://www.scholarnext.com
