The Sight Reduction Tables for Air Navigation (Pub 249) are published in three volumes. Volume 1, used by both marine and air navigator, contains the altitude and azimuth values of seven selected starts for the complete ranges of latitude and hour angle of Aries. These seven starts represent the best selection for observation at any given position and time, and provide the date for presetting instruments before observation and for sight reduction afterwards. Volumes 2 and 3 cover latitudes 0°-40° and 39°-89° respectively and are primarily used by the air navigator in conjunction with observations of celestial bodies to calculate the geographic position of the observer.

Crosspool Through Time contains 180 photographs of Crosspool, of which 90 are old photographs. Some are printed in a sepia tone and some are printed in full colour. These photographs are printed alongside a contemporary full colour photograph which illustrates the same scene. The contrasting illustrations show how the area has changed and developed during the last 100 years. The photographs illustrate shops, schools, garages, churches, houses and street scenes, each photograph is captioned and the book has an introduction which gives a brief overview of the history of the town. As you browse through the photographs, you will notice the increase in the number of vehicles on the road, shops that once sold new goods are now estate agents or charity shops. Green fields have been transformed into industrial estates, houses or ring roads.
