fore threatened if no other facility can take them) geoscience data and collections are major oil companies, independent petroleum producers, and mineral extraction companies (AGI, 1997). An American Geological Institute survey (AGI, 1997) estimated how much material these groups would consider contributing to the public domain if facilities existed to receive the information. Sidebar 2-1 summarizes these results. Table 2-2 shows examples of donations of core from industry to the public sector since 1994.
A NATIONAL SHORTAGE OF SPACE
Although it is difficult to quantify the amount of space available in the nation’s repositories, many are essentially at or near capacity. Repository managers therefore are refusing to accept new data and collections because they simply do not have enough space in the repository. Figure 2-2 illustrates the amount of space available at state geological survey repositories around the United States, and Tables 2-3a and 2-3b summarize, respectively, the available space at state geological surveys and at other entities across the nation. Of the 35 responding state geological surveys, nearly two-thirds have 10 percent or less available space, and nearly one-quarter are entirely full. At least one-third of the state geological surveys listed in Table 2-3a have been forced to turn away geologic materials, and more than three-quarters of them could not add new space. The cross-section of other geoscience repositories around the country (Table 2-3b) reveals similarly low amounts of available space.
The following situation is typical: because of limited space, a repository can accept core and other physical data only if it discards a similar volume. The result is that every time something is added, something else must be removed. The repository can apply its own set of criteria, but without formal protocols to set priorities, valuable data and collections may be at risk from the limited assessment of a single individual. Repository managers may try to preserve geoscience data and collections in other ways, such as by offering discarded material to other qualified organizations or using it in other ways (e.g., student study sets).
Because of the vagaries in knowing how much new material might be offered, repository administrators often have difficulty estimating how quickly remaining space will fill up. Examples include the state geological surveys of Kansas, Kentucky, and Ohio, all of which have added new space

Nearly two-thirds (63 percent) of the state geological surveys that responded to the committee’s questionnaire reported that they have 10 percent or less remaining space for geoscience data and collections.
