Abstract
IT has often been remarked in this journal that, of all the branches of the engineering profession, production engineers are the least articulate. The recent conference at Cranfield accepted this as a regrettable fact and proceeded to discuss the reasons for it, and how to increase the interchange of information between production engineers. In a majority among those attending the conference were members of A.S.L.I.B., but there were a number of production engineers, although these were naturally drawn from the firms most fully aware of the value of information services, and so the conference was to some extent preaching to the converted.

Abstract
Information and special library work is at present a profession that is in the process of formation and struggling for recognition, and entry into it is entirely uncontrolled. People with the most varied backgrounds and levels of education find themselves made responsible for setting up or running library and information services, without any previous knowledge of the work. Often they are in remote places and without any contact with more experienced colleagues who could give them advice, and their only means of getting the knowledge necessary for the efficient carrying out of their duties is from reading. But, owing to the unsettled state of the profession, the literature is voluminous and scattered, and much of it is of a low standard, or occupied with pure theorizing or polemics. Moreover, the literature that the novice is most likely to see, namely the articles on documentation which are occasionally printed in technical journals, is not always the most helpful for a person who has no background of experience against which he can evaluate it. In these circumstances the new entrant needs a guide to the literature if he is not to be discouraged or adopt practices and systems which are not really suitable to his circumstances. It is to meet this need that this annual review of the literature, now in its sixth year, has been written. It attempts to select those books and papers which are most likely to be of direct help in running a small information department or library, eschewing all pure theorizing and polemics, and only including literature on large libraries where it is felt that it contains ideas capable of application in smaller organizations. To these are added a selection of the most important works of reference, including some that the information officer may wish to know about and consult in other libraries, even though his own library does not possess them. The list is not restricted to work published in 1957, but is intended to be representative of items received in British libraries during the period under review. Owing to restrictions in space, the selection has to be rigorous, and is inevitably, to a certain extent, a personal one. No two people would probably agree on all the omissions, but it is hoped that all the items included will be of positive value to the type of reader for whom the review is intended.

Abstract
Purpose
The main objective of the paper is to explore the theoretical correlation of base oil viscosity in grease and to study the effect of grease grade on mechanical vibrations associated with the damaged rolling bearings.
Design/methodology/approach
For theoretical purposes, formulation theory of dimensional analysis was implemented. Experiments were then performed on the test bearings lubricated with three different types of greases, namely, SKF LGHP2, SKF LGMT3 and SKF LGWA2.
Findings
The numerical results obtained from the theoretical model along with the results of experiments show that the vibration amplitudes of the defective bearings come down to a lower level when it is lubricated with the grease of a higher base oil viscosity.
Research limitations/implications
The promising results from the theoretical model make it usable for the practical rotating machineries applying a variety of the rolling bearings. Consequently, if the bearing is not severely damaged, its performance can be increased by lubricating it with thicker grease.
Originality/value
Despite many significant contributions in the field to detect the presence of defects, not many studies have been performed that relate the lubrication condition of the rolling bearings with the vibration response, because around 50-75% of the bearing failures are attributed to be lubrication related. Hence, there is need to develop a mathematical model that can correlate the vibration severity of the bearings with viscosity of the lubricant oil in the greases along with other design and operating parameters.

Abstract
ASLIB made a break with tradition when the Thirty‐first Annual Conference was planned to take place at Brighton from 1st to 4th June, 1956, instead of in the autumn. Alas, that the weather did not play its part. A stiff, chill breeze discouraged any lingering on the sea front and by Sunday night this had degenerated into a howling gale of wind and rain. However, there are two sides to every coin. Possibly the lack of counter‐attractions contributed to larger attendances at the meetings and to the many impromptu gatherings in the foyer of the Hotel Metropole where the conference was held. Most people appeared to enjoy themselves.

Abstract
Though the title on our cover implies no startling novelty, this first issue of Aslib Proceedings: incorporating Aslib Information is, nevertheless, a step of some significance in the publication of Aslib's periodicals. From now on, the quarterly Aslib Proceedings and the members' monthly news‐sheet Aslib Information will cease to be published separately. Instead, the papers, news notes, lists of recent articles and Aslib library accessions which have hitherto appeared in them, together with certain other types of material for which Aslib has had no suitable publication medium, will be brought together in this new monthly periodical. This, as befits a record of papers read at Aslib meetings and a chronicle of the plans and activities of all of Aslib's component parts, is visualized as a service common to members of all categories and one of the principal links between them.

Abstract
This chapter extends the phenomenographical research method by arguing the merits of engineering the outcome space from these investigations to effectively communicate the outcomes to an audience in technology-based discipline areas. Variations discovered from the phenomenographical study are blended with pre- and post-tests and a frequency distribution. Outcomes are then represented in a visual statistical manner to suit the specific target audience. This chapter provides useful insights that will be of interest to researchers wishing to present findings from qualitative research methods, and particularly the outcomes of phenomenographic investigations, to an audience in technology-based discipline areas.

Abstract
The important series of mechanical charging systems known generally as Indicators, have never been fully described, either from the historical or structural standpoint. Papers describing one or other of the individual varieties have been published from time to time during the period of thirty‐six years they have been in use, but except the partial notices of a select few published by Mr. F. J. Burgoyne and myself, nothing of a comprehensive or accurate nature has ever appeared. Before proceeding to describe each separate invention in its order, it may be well to enquire briefly into the reasons for the origin of a device which has called forth not a little ingenuity and inventive talent. When libraries were first established under the provisions of the various Acts of Parliament, two things happened as a matter of course in every district: a building, suitable or otherwise, was provided; and, the readers in a town increased in number to an enormous and unprecedented extent. Straitened means generally led to the provision of a cramped and inconvenient building, in which the space set apart for books was often ridiculously inadequate; with the result that lofty shelves were the rule, which secured economy of storage at the expense of rapidity of service. Previous experience in mechanics' institutes, or similar libraries, was found by the new librarian a useless criterion for public library needs, and especially as a guide to the multitude of readers and the variety of their demands. Delays in service occurred continually and the poor librarian was often abashed or offended at the freely expressed scepticism with which the public received his reports of books being out. From these factors was evolved the idea of the indicator, which by and by took practical shape as a machine for saving the legs of the librarian and his assistants from frequent and fruitless climbs to high shelves, and enabling readers to satisfy themselves that books were actually in use. The original indicators were intended only for showing, by means of numbers, the novels which were out or in, but since then a considerable number of libraries have applied them to all classes.
