The following books are highly recommended for those individuals interested in further information:
Robert W. Baumbach: The Victor Data Book. Published by Mulholland Press, Los Angeles, California. Here's the ultimate resource for Victor Talking Machine collectors and hobbyists. Covers every production detail of the external horn, internal horn and Orthophonic phonographs and radio-phonograph combinations produced by Victor. Over 300 pages of data, photos and explanations.
Robert W. Baumbach: Look for the Dog: The Victor Talking Machine Companion Published by Mulholland Press, Los Angeles, California. This outstanding book is the "bible" for collectors of Victor products, and includes detailed listings of each model, dates produced, prices, and a great deal of historical information. An excellent and well written guide for the collector or enthusiast.. All my copies are worn to a frazzle from constant use. Highly recommended.

James N. Weber: The Talking Machine: The Advertising History of the Berliner Gramophone and Victor Talking Machine Published by Adio, Inc., Midland, Ontario, Canada. This is a compilation of vintage advertisements and promotional literature issued by Victor (and a few others) throughout the years, and provides an excellent cross-section of the Victor product line, as well as providing the enthusiast an opportunity to understand the mindset of Victor's management as these products were being promoted. Some rare machines are presented as well.
Eric L. Reiss: The Compleat Talking Machine Published by Sonoran Publishing, Chandler, Arizona. Currently out of print, but copies are still available from some booksellers. This is a comprehensive restoration guide for all antique phonographs (not just Victor products), and should be considered "essential reading" for all collectors and enthusiasts. Excellent non-technical overviews of phonograph operation are provided, along with some wonderful tips for repair and restoration. This is a book no hobbyist should be without.
Walter L. Welch and Leah Brodbeck Stenzel Burt: From Tinfoil to Stereo Published by the University Press of Florida (1994 edition). This text has been recently revised (and shortened) from its 1959 original, and some of the information on later Victor products (especially the Orthophonics) has been eliminated in the newer edition. There are many errors and oversights, and often an editorial bent against Victor. Regardless, this remains a good book on the early years of the phonograph, but with a strong emphasis on Edison products. Much information is provided on the legal battles between the major phonograph manufacturers.
Vibration and Acoustics:
There are scores of outstanding technical books available on the topic of vibration and acoustics, most of which are highly theoretical and dwell extensively on mathematics and derivations. However, I have found several texts which are well suited for the hobbyist. They are readable and quite comprehensive.
Cyril M. Harris: Handbook of Acoustical Measurements and Noise Control Published by McGraw Hill, Inc. The Handbook is essentially an engineer's reference manual on acoustics, but it is written in a style that is easily understood by the serious hobbyist who has had some mathematical background. Excellent introductory material is provided on waveforms, signals and basic definitions. Strongly recommended.
J.R. Hassall, K. Zaveri: Acoustic Noise Measurements Published by Bruel and Kjaer, Denmark This text is intended as a guide for making accurate noise measurements. It does provide an excellent overview of acoustics, but some sections require an understanding of complex algebra and and calculus. Outstanding diagrams and verbal descriptions are provided on acoustic principals and signal analysis.
Kinsler, Coppens, Frey, Sanders: Fundamentals of Acoustics Published by John Wiley and Sons, New York. A highly technical book which provides an outstanding overview of impedance matching and exponential horn theory for engineers and scientists.
