This website was the first devoted to light pollution on the emerging World Wide Web and has always been among the most-accessed websites on this topic; the first official IDA website was also hosted here alongside this NELPAG website in the mid-1990s (due to the pre-existing NELPAG website and its success, as a favor to the IDA). A big role of NELPAG has been providing information through this Website since early 1995, with hundreds of accesses to this page being logged every week for many years (the week ending 1997 May 4 had 766 accesses to this page in that week alone; by August 1999, this webpage was accessed over an estimated 100,000 times since 1995). We have found that there is a great public demand for information on outdoor-lighting issues; prior to the establishment of websites like this, there had been a great dearth of sources that the interested individual could seek out for information on outdoor lighting. It should not be surprising, then, that we have received high praise from many people around the world for the information provided here.
Many outdoor lights are, in fact, completely unnecessary (such as most lights late at night, and streetlights along most limited-access highways, where 6-foot-high median barriers would provide much greater safety). On a separate webpage here, we outline the key light-pollution issues.

This page is maintained by D. W. E. Green [dgreen (at) eps.harvard.edu]. These pages were produced and made available here because of the prominence of this problem to cometary observers, and in support of IAU Resolution 2 at the 20th General Assembly of the IAU, which "strongly urges (a) that all astronomers request civil authorities and others in their countries to implement solutions to preserve the quality of observing conditions, and (b) that all national organizations bring these concerns to the notice of adhering organizations, space agencies, and others in their countries" (IAU Today No. 10, 1988 Aug. 11).
