Massive Stars: From α to Ω, held 10-14 June 2013 in Rhodes, Greece; Online at http://a2omega-conference.net, id.101 (2013).
Coinciding with this meeting, we are publishing the first data release of GOSSS. This release contains [a] revised spectral classifications and [b] blue-violet R~2500 spectra in FITS format for ~400 Galactic O stars, including all brighter than B=8. DR1 (and future releases) will take place through GOSC, the Galactic O-Star Catalog (http://gosc.iaa.es), which will be updated for the occasion. Since 2011 GOSC runs on a MySQL database and allows for queries based on coordinates, spectral class, photometry, and other parameters. Future data releases will include the rest of the stars observed in GOSSS (currently 1521 with ~1000 more planned in the next two years).
