A cool-star UV spectral catalog--CoolCAT-- will improve dramatically the accessibility and utility of the rich stellar archive of STIS E140M/H and E230M/H exposures. CoolCAT will contain digital spectral atlases--echellograms processed to the same uniform standard, multiple observations graded and coadded, and adjacent wavelength regions concatenated--and a supporting catalog of line identifications, wavelengths, widths, and fluxes. Semiautonomous line fitting procedures will ensure a homogeneous and uniform treatment of the diverse spectral material. Valuable experience already has been gained with cycle 8 project 8280, which obtained full UV echelle coverage {1150-3000 Angstrom} of 13 representative late-type stars. My personal interest in these data involves studies of gas dynamics in stellar outer atmospheres, traced by emission line Doppler widths and shifts. However, a wide range of other investigations--from the photochemical evolution of primitive planetary atmospheres to galactic population synthesis--will be enabled by CoolCAT.
