Yesterday I received my copy of Gerhard Stoehr's new book (in German)  "Aneroid-Barometer, die robuste Alternative". It is an excellent guide to the history of aneroid barometers.  Although my German is very rusty, the book is loaded with color photographs and illustrations that make it useful to any barometer collector or instrument historian.  I highly recommend it.  Ordering information was provided in my August 18, 2016 blog post on this website.

Also, I moved the pages regarding calculation of local pressure from mercury barometer data and the calculation of sea level pressure from local pressure data.  They may now be found in the 'Barometric Calculations, Calibration and Accuracy' link on the home page of this website.
