The Splatalogue is an attempt to collate, rationalize and extend existing spectroscopic resources for use by the astronomical community. Currently, Splatalogue is a transition-resolved compilation of the JPL, CDMS, Lovas/NIST, and Frank Lovas' own Spectral Line Atlas of Interstellar Molecules (SLAIM). Currently, Splatalogue contains over 3.9 million lines in 720 unique chemical species. Open access starts with splatalogue v.1.0 at www.splatalogue.net.
