All About Coffee

Title: All About Coffee

Author: William H. Ukers

PREFACE

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.
