The sample of 379 extragalactic sources is presented that have mid-infrared,high resolution spectroscopy with the Spitzer Infrared Spectrograph (IRS) andalso spectroscopy of the [CII] 158 um line with the Herschel PhotodetectorArray Camera and Spectrometer (PACS). The emission line profiles of [NeII]12.81 um, [NeIII] 15.55 um, and [CII] 158 um are presented, and intrinsic linewidths are determined (full width half maximum of Gaussian profiles afterinstrumental correction). All line profiles together with overlays comparingpositions of PACS and IRS observations are made available in the Cornell Atlasof Spitzer IRS Sources (CASSIS). Sources are classified from AGN to starburstbased on equivalent widths of the 6.2 um polycyclic aromatic hydrocarbonfeature. It is found that intrinsic line widths do not change amongclassification for [CII], with median widths of 207 km per s for AGN, 248 kmper s for composites, and 233 km per s for starbursts. The [NeII] line widthsalso do not change with classification, but [NeIII] lines are progressivelybroader from starburst to AGN. A small number of objects with unusually broadlines or unusual redshift differences in any feature are identified.
