ALL ABOUT COFFEE
SEVENTEEN years ago the author of this work made his first trip abroad to gather material for a book on coffee. Subsequently he spent a year in travel among the coffee-producing countries. After the initial surveys, correspondents were appointed to make researches in the principal European libraries and museums; and this phase of the work continued until April, 1922. Simultaneous researches were conducted in American libraries and historical museums up to the time of the return of the final proofs to the printer in June, 1922.
Ten years ago the sorting and classification of the material was begun. The actual writing of the manuscript has extended over four years.
Among the unique features of the book are the Coffee Thesaurus; the Coffee Chronology, containing 492 dates of historical importance; the Complete Reference Table of the Principal Kinds of Coffee Grown in the World; and the Coffee Bibliography, containing 1,380 references.
