In the last editorial, I brought to your attention some new and expanded policies of the editorial staff of Optical .Engineering. At that time, we expressed the desire that future issues of the Journal would include specials featuring optical engineering at various major industrial and private institutions. The May-June 1973 issue will include in addition to other papers, a special section of five papers describing "Optical Engineering at the National Bureau of Standards". In addition, we are in the process of soliciting papers for a special feature dealing with microdensitometric techniques and their applications, and we hope to bring this to fruition in a later issue this year. Our readers can look forward to future specials such as Optical Engineering at Avco-Everett, Optical Testing and Fabrication, Environmental Optics, Optical Engineering at the Retina Foundation, and Electro-O ptics.
