DESCRIPTION:Rest-frame far-ultraviolet (FUV) spectra are fundamental to ou
 r understanding of star-forming galaxies\, providing a unique window on ma
 ssive stellar populations\, chemical evolution\, feedback processes\, and 
 reionization. The launch of JWST and construction of the ELTs will soon us
 her in a new era\, pushing the FUV spectroscopic frontier to z=15-20. The 
 success of these future endeavors hinges on a comprehensive understanding 
 of the massive star populations and interstellar medium (ISM) gas conditio
 ns that power the observed FUV spectral features. I will present the COS L
 egacy Archive Spectroscopic SurveY (CLASSY) Treasury as a powerful and pro
 mising solution. CLASSY is a large HST program creating the first high-qua
 lity\, high-resolution FUV spectral catalog of star-forming galaxies at z=
 0\, but which span similar properties as seen at high-z. The spectra conta
 in a suite of emission and absorption lines that characterize the massive 
 stellar populations that populate metal poor galaxies\, the physical prope
 rties of large-scale outflows that regulate star formation\, and the chemi
 cal abundance patterns of the gas and stars. CLASSY will improve the diagn
 ostic power of the FUV lines for future JWST/ELT surveys\, providing a lon
 g-lasting legacy to the astronomical community for decades to come.
