The Library Shelf

This is an indispensable book for all fatigue workers, and a most useful one also for the structural engineer. Of the eighty‐one papers published, eleven, those of the greatest aeronautical interest, were summarized in AIRCRAFT ENGINEERING, December 1956, and thus there is no need for the reviewer to use space for their description. Instead, he can devote himself to the final picture as it emerged from the Discussions and the Authors' Replies which is a valuable part of the book, comprising 190 pages and containing also the corresponding parts of the follow‐up meeting held in New York. A noteworthy and generally appreciated feature of the Conference which is retained in the Proceedings was that both in London and New York the individual papers were introduced and commented upon by a total of nineteen reporters, who also took part in Plenary Sessions in which their final summing‐up was done with reference to the position obtaining after the Discussions were completed.
