These ESICs provide information about geologic, hydrologic, topographic, and land use maps, books, and reports; aerial, satellite, and radar images and related products; earth science and map data in digital format and related applications software; and geodetic data. ESICs can fill orders for custom products such as aerial photographs and orthophotoquads, digital cartographic data, and geographic names data. ESICs can also provide information about earth science materials from many public and private producers in the United States using automated catalog systems for information retrieval and research services"--What's an ESIC? screen
