A study was conducted to assess the value of the Energy Data Base (EDB), which is produced by the Technical Information Center (TIC) of the Department of Energy (DOE) in order to provide a means of identifying primary energy information sources, particularly journal articles and technical reports. The volume of energy information distributed to and used by the DOE-funded research community was identified, and value was determined in terms of user willingness to pay for information, the effect of information obtained on work, and the effect of the work performed on organizations and society. Two types of value were computed: apparent value, or the amount paid for information in terms of time and money; and consequential value, or the savings achieved by the application of the information. Data used came from TIC records and a previous survey of scientists and engineers which identified the value associated with the reading of journal articles and technical reports in terms of both dollars and time saved. It was found that savings of equipment resulted from the use of EDB products and services, and benefit-to-cost ratios for EDB searching and reading were identified as 5.9 to 1 and 31 to 1 respectively. This report contains an executive summary and technical documentation of the study. Sample questionnaires and a 47-item bibliography are provided. (ESR)
