Ross FOREWORD The Oregon Forest Products Laboratory has conducted considerable experimen-. taJ.. work on wood carbonization, was compiled. In the course of this work a sizeable bibliography While the work on carbonization has been curtailed for some time, it was thought desirable to bring the bibliography up to date nd make it available as a reference source, This bibliography covers published work on wood distillation for the period 1907-l9S3, The material is classified in the following divisions: Books--listed alphabetically by author's name. Articles and Bulletins--primary listing is chronological with secondary alphabetical listing by author's name. Patents--listed alphabetica1l by country, chronologically by year of issue, and alphabetically by author's name. The term wood distillation is used rather loosely in the literature, consequently references may cover carboniatjon, steam distillation, gasification or modifications of each. It is the main purpose in the bibliography, however, to cover wood carbonization and topics related primarily to wood charcoal. Three abstracting services were used for the bulk of the assembled references; Chemical Abstracts (1907 to date), Forestry Abstracts and Engineering Index (1907 to date). (1939 to date), Chemical Abstracts was used as the primary reference source, and where possible, Chemical Abstracts references are included along with the original reference. BOOKS Bunbury, H. N.
