Although the tables have been compiled foruse primarily by the apprentice, the specialized worker will also find them useful. Every effort has beenmade to shorten the sometimes tedious operations and the arrangement of subject matter is such thatits contents are readily available to the practical man. Much painstaking effort must go in compiling and arranging such tables. Infonnation must be so selectedthat the reader can, from the bulk of material, easily find out the subject of his interest. Often, a decisionofeither selecting anitem or rejecting itproves difficult. Too much material packed into tabular compilations can be as hannful a~the omission of some vital pieces of infonnation. Not only the selection but also the arrangement of material requires considerable thought if the contents of the tabular compilations have to be offered for ready reference. Only then can the reader decidewhere to look for proper infonnation. The principle of order must be evident at once. The authors and publishers hope that they have succeeded in fulfilling their special tasks. However, suggestions for improving the tabular compilations are welcome.
