In terms of notability, within the US, discussions about LiDAR (and it's availability) tend to be found most readily in either (1) government publications, such as those discussing the National Elevation Dataset or related efforts at NOAA or USDA, one example of which is the 2007 publication of the First National LiDAR Initiative Meeting  or (2) industry publications such as those covering GIS and remote sensing, including Directions Magazine, Spatial News, GeoSpatial Solutions, 
GeoWorld, GPS World,GIS Vision, GIS Monitor, URISA Journal, Photogrammetric Engineering and Remote Sensing, GITA, and Point of Beginning.
