1. Anne Kenney is the associate director of preservation at the Cornell University Library. She has also contributed to this work; see chapter 2, ''Digital Image Quality: From Conversion to Presentation and Beyond." [BACK]

2. We did agree to work with three scholarly associations-the Ecological Society of America, the American Economic Association, and the American Political Science Association-to provide access to current issues through JSTOR. We stand by our commitments to these organizations, but our goal is to learn more about the technology required to make linkages between current issues and the archive, not to build the capability for JSTOR to become a publisher of current issues.

3. In the not-for-profit context, a revenue-generating market need not consist solely of paying customers; it could include other types of indirect funders like government agencies or foundations. [BACK]

4. To refer to these costs as one-time costs is not precisely accurate. Not all of the production costs are one-time. We add another volume of each journal title to the database as each year passes, so there is an ongoing element of the production costs, but that element represents a small fraction of total production expenditures. [BACK]

5. There is a caveat here as well. Some of the administrative and overhead costs are higher because JSTOR is adding titles. Negotiating agreements with publishers is a timeconsuming task, as is overseeing the production operation converting 100,000 pages per month. It is not practical, however, to allocate exactly the portion of general administrative and other costs that pertain directly to production. [BACK]
