permit the development of a data base that could be analyzed statistically. Information from the returned questionnaires was entered into a machine-readable data base that forms the basis for this report. The original data base is on file with the Oklahoma Geological Survey and is available for public access.

Of the 1083 returned questionnaires, 501 represented responses not only for an individual, but for his or her organization as well. Of those responding for organizations, 304 were from organizations employing 1 to 5 users of geoscience maps, 180 for 6 to 20 users, 76 for 21 to 100 users; and 35 for those having more than 100 users of geoscience maps. The combined representation from these respondents and the 581 respondents answering only for themselves is estimated conservatively to be more than 12,000 map users (see Table 3).

Questions 5 to 13 (see Appendix A, a duplicate of the questionnaire) were constructed to be answered by the responses “extremely important, moderately important, and not important.” In some cases, a respondent was able to answer to more than one item in a question with one of the three responses. As a result, totals for some questions are greater than the number of respondents. In order to provide consistency in the analytical procedure, the following analysis is based only on the number of “extremely important” responses.
