  The sample of 379 extragalactic sources is presented that have mid-infrared,
high resolution spectroscopy with the Spitzer Infrared Spectrograph (IRS) and
also spectroscopy of the [CII] 158 um line with the Herschel Photodetector
Array 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 line
widths are determined (full width half maximum of Gaussian profiles after
instrumental correction). All line profiles together with overlays comparing
positions of PACS and IRS observations are made available in the Cornell Atlas
of Spitzer IRS Sources (CASSIS). Sources are classified from AGN to starburst
based on equivalent widths of the 6.2 um polycyclic aromatic hydrocarbon
feature. It is found that intrinsic line widths do not change among
classification for [CII], with median widths of 207 km per s for AGN, 248 km
per s for composites, and 233 km per s for starbursts. The [NeII] line widths
also do not change with classification, but [NeIII] lines are progressively
broader from starburst to AGN. A small number of objects with unusually broad
lines or unusual redshift differences in any feature are identified.
