A USER'S ASSESSMENT OF CURRENT AWARENESS SERVICES Available to Purchase

Before one looks at services intended to make one aware of current progress in science, one should look briefly at the structure of science and at how, and perhaps why, information is generated. It has long been an administrative convenience to divide science into a number of quite well‐defined fields such as biology, physics, chemistry, etc., and to further subdivide these, again largely for administrative reasons. Chemistry, for example, may be divided into inorganic, organic, physical, etc. branches.
