As previously described in M. Smith et al. 2007AAS...211.4709S, we have constructed a spectral classification digital coding system that assigns the full spectral type, class, and spectral peculiarities for stars in an archival database or catalog. This service is also described in a IVOA Design Note. To develop this into a user-friendly tool, we have developed an interface that permits requests for lists of names of stars that have a uniform range of common spectral type properties as long as they have been observed by missions supported by MAST (Multi-Mission Archive at Space Telescope). Depending on their research goal researchers can use the list to download representative MAST-held spectra of "like stars" and/or all the MAST held spectra for them. Although this tool facilitates research on individual stars, its primary purpose is to provide a new ability to collate data for special purposes, such as construction of spectral atlases or to facilitate like star queries using VO spectral services like VOSpec and Specview. As a parallel service, the interface permits users to obtain spectral classification from the Skiff catalog. In addition, if the spectral type is known, it can be listed in retrievals following queries to the standard MAST mission data search forms.
