Spectroscopy is the main key to astrophysics. Without it, not only our current picture of the Universe but also the actual understanding of the atomic structure and quantum mechanics would be unthinkable. Therefore, most of the larger professional optical observatories use a significant part of the telescope time for the recording of spectra. Over recent years technological advances like CCD cameras, and also affordable spectrographs, have come on the market, causing a significant, but surprisingly late, upturn of this crucial and fascinating discipline within the community of amateur astronomers. This remarkable evolution creates unique opportunities for amateur astronomers to make significant contributions to a broadening of spectroscopic survey programs. Nowadays these activities are further supported by excellent freeware programs documented by detailed manuals, which are even supplemented with step-by-step tutorials, provided by numerous Internet sources. This evolution in spectroscopic hard- and software stimulates the rise of symbiotic cooperation within scientific projects between professional and amateur astronomers.
