The incomparable Ross Quail, president of the Australasian Specialty Coffee Association has posted on the AASCA site the exciting news that the William H. Ukers coffee text "All About Coffee" is now out of copyright and as such project Gutenberg have undertaken to make it available electronically - free of charge. This occurs whenever sufficient time passes after the death of an author to be sure that the author's estate has benefited as much as is reasonable from the product of that author - I think about 50 years or so.
There are a variety of formats available including ePub - which can be read on laptops, desktops iPhones and other smartphone - and naturally, iPads.
You can find the book here: http://www.gutenberg.org/etext/28500
Thanks to Ross and AASCA for spreading the news as I know there are many people who cannot afford the several hundred dollars for a paper version of the text.
