crl-12151	Sheehy, Eugene P.	Selected Reference Books of 1968-69	1969	10	.pdf	application/pdf	6209	382	59	At first the work seems difficult to use, especially where the number of citations (as under the head of the Russian Republic) is considerable, but the preface tells us that the order be- gins with the Marxist-Leninist classics· then, under each national heading lists of general works are followed by works on specific topics, and by a personal author section. Omitting works on the his- tory of science, the bibliography treats all areas from general works on the history of technology to such specific subjects as de- velopment of musical instruments, time- keepers, and the assembly line.	cache/crl-12151.pdf	txt/crl-12151.txt
