Metes and Bounds — Council on Library and Information Resources

A survey by metes and bounds is a highly descriptive delineation of a plot of land that relies on natural landmarks, such as trees, bodies of water, and large stones, and often-crude measurements of distance and direction. This was accepted practice before more precise instruments and methods were developed—indeed, the original 13 U.S. states were laid out by metes and bounds. More accurate means of measuring were established to overcome the methods serious shortcomings: streambeds move over time, witness trees are struck by lightning, compass needles do not point true north, and measuring chains and surveyor strides can be of slightly differing lengths. However, the metes and bounds system is still used when it is impossible or impractical to make more precise measurements.

In undertaking our survey of the e-journal archiving landscape, we found that precise measurements and controlled data collection were not always possible. The e-publishing terrain is changing at time-lapse photography speed. Definitions and terms are widely interpreted, and standards are not yet established. These factors, along with our need to rely heavily on self-reporting by the programs, mean that direct comparisons between them may not always be valid. Despite this, we describe in this report the current lay of the land for scholarly e-journal archiving.

This study focuses on the who, what, when, where, why, and how of significant archiving programs operated by not-for-profit organizations in the domain of peer-reviewed journal literature published in digital form. Not included are preservation efforts covering digitized versions of print journals, such as JSTOR; library-led digital conversion projects; self-archiving efforts by publishers; and initiatives still being planned.

In preparing this report, our team focused on the following:

soliciting library directors concerns and perceptions about e-journals;

compiling responses from e-journal archiving initiatives taken from written surveys and semistructured interviews; and

analyzing the issues and current state of practice in e-journal archiving, and forming recommendations for the future.

We began the study by developing a list of what library decision makers are likely to consider as they assess preservation strategies for e-archiving. The list was informed by our own research, discussions with colleagues, and comments made to staff members of the Center for Research Libraries (CRL) by member library directors.

During March and April 2006, 15 North American library directors, representing a range of public and private institutions of various sizes as well as consortia, participated in telephone interviews designed to solicit their views on six key areas:
