A reference for writers

For all I know I may have mentioned this before, but ...

The Pocket Reference, by Thomas J. Glover might belong on your shelf.  If you need backgound information, on how to signal a crane operator or give first aid, on the weight or strength or ropes, on minerals or clouds, on electrical wiring, on glues or on gluons, on nuts and bolts or winding a radio frequency coil, on airline codes or car rental codes or the codes molded into tires, on ASCII codes or area codes (worldwide), on handsaws or circular saws or fire extinguishers, on the configuration of electrical plugs around the world (and the voltages they're used for), on military ranks and insignia, on life expectancies or the masses and orbits of Sols planets, on wind chill or consanguinity, on flow over a dam or daylight savings time, you might just find this big little black book useful.
