New York: Bell Telephone Laboratories, Inc. 1951. First Thus. , 792 pages. Original thick grey cardboard covers. Ex corporate library from an important research laboratory: "R.C.A. Laboratories Division, Princeton, N.J." with their stamp on the title page and bookplate on inside cover with large withdrawn stamps. Stamped 8780 on Foreword page. Well read, with a number of places where the binding has been reinforced with tape. Some signatures "proud" of the backstrip, sewing loosening. Could use a proper rebinding/resewing, or simply used as is as a reading copy. Occasional markings internally. Good. Stiff wraps. 
This report contains 34 articles plus the introduction covering material given at a symposium on transistors held at the Bell Telephone Laboratories during the week beginning Sept. 17, 1951. It includes work from luminaries like William Shockley (1956 Nobel Laureate in Physics with Bardeen and Brittain for "their researches on semiconductors and their discovery of the transistor effect") who contributed to three articles including "Holes and Electrons" (derived from his similarly named book) and "The Theory of p-n Junctions in Semi-Conductors and p-n Junction Transistors" (published previously in the Bell System Technical Journal).
From the transistor's invention in 1948 through the early 1950s the fledgling electronics industry was encouraged and funded by the military, driving significant research into this startling new technology and it's potential. In retrospect, the transistor was one of the most signficant inventions of the 20th century. Moore's law and the continual shrinking of transistor devices from a single device the size of a pea (illustrated herein) to many many thousands of transistors in the same space have driven the computer revolution and fundamentally changed our society in the process.
This symposium details work conducted by primarily Bell System researchers to share what was then known, much of it conducted under government contracts and previously unpublished. The symposium treats "theory, transistor properties, circuit design principles, applications, and finally, characteristics of different transistor types [then] under development." As the Foreword notes: "It will be recognized that, in a broad sense, this constitutes by a progress report. The art is moving rapidly. There are still many problems to be solved and some of the material [reported] may be soon out of date. It is too early for a full appraisal of the extent to which the transistor may find its place in the field of electronics. Just now it is a promising infant trying to shed its swaddling clothes. It is hoped that this [report] will assist in this effort. Bell Telephone Laboratories, Inc. Murray Hill, N.J. November 5, 1951."
Previous owner R.C.A. Laboratories was an important research laboratory which after the war did serious work in transistors. (cf ethw wiki for a nice summary) If you're going to own an ex-library copy of this work (nice copies are selling for nearly four figures now) this is a nice association copy.
Important, early work in the field of electronics.
