Excerpt from General Alphabetical and Analytical Index: Transactions of the American Institute of Mining Engineers; Volumes 36-55, Inclusive (1905-1916) It was customary formerly to publish an index of the Transactions about every fifth volume, but since the Institute began in 1913 to publish three volumes instead of one volume per year, this has been deemed impracticable and unnecessary. No collective index has been published since the one covering Volumes I to XXXV inclusive, except ing a short one covering Volumes XXXVI to XL inclusive. The Board of Directors, therefore, upon the recommendation of the Committee on Papers and Publications, decided to publish this index of Volumes XXXVI to LV inclusive, and thus enable members to have in condensed space the collective indexes of all the volumes of the Transactions.
