Introduction

Development of the Index of the Bulletin of the Scientific Instrument Society

The first 40 issues of the Bulletin were indexed successively, ten issues at a time. With the advent of No 50 it was decided to amalgamate the earlier work and create a single index for all 50 issues. The work involved was a vast undertaking requiring the use of optical character recognition and other computer techniques on the earlier work, and a good deal of careful proof reading. The final product was handsomely produced in A4 size uniform with the Bulletin, running to 64 index pages.

Having reached 80 issues, a similar combining exercise has been done, but with fewer categories within the Index. However, whilst the main index of individual topics remains as comprehensive as previously it is presented in a smaller typeface and makes use of more columns.

At the time of printing, consideration is being given to the use of this new Index as a facility on the Society's website and also in connection with CDROMs of the Bulletin.

Notes for using the 3 sections of the Bulletin Index, Issue No 1 to Issue No 80

Index of Topics

Topics are arranged alphabetically by subject. References are shown as 'Issue No : Page No' eg 2:15 or 45:7-11

Index of Articles

Authors of articles are listed alphabetically with the titles of their articles following in issue order. The issue in which an article may be found is referenced in italic bold, eg 76

Index of Book Reviews

Authors of books, etc, reviewed are listed alphabetically with the titles of their publications listed in issue order. The reviewer's name in shown in parentheses after each title and is followed by a similar 'Issue No : Page No' reference to that used in the Index of Topics.
