Abstract
Finance textbooks typically state that 8 to 20 stocks can provide adequate diversification for a portfolio. However, these recommendations usually assume a short time horizon such as one year. We examine 20‐year cumulative rates of return and ending wealth from an initial $100,000 investment allocated among 100 large U.S. stocks. Probability distributions obtained from simulations illustrate the shortfall risk faced by investors who own fewer titan 100 stocks. Five percent of the 20‐stock portfolios have ending wealth shortfalls exceeding 28%. These findings suggest that 8 to 20 stocks may be insufficient for long‐term investors.

Abstract
THE Programme of the Library Association Conference which reached us on April 22nd is one of much interest. Every year increases the difficulty of providing matter which has such appeal that members can say at the close that the time has been spent profitably. The pre‐print of the papers—a rather incomplete affair—raises the thought that Conference time could be better used than in discussions on such “Research Committee” matters as library vans and temporary buildings, excellent as we admit the enquiries and results of them to be. Yet this reflection is accompanied by the certainty that there have been few conferences which have not contributed something of material use to every participator and we still hold the view that more is learned in “a week at one than in months of hermit‐like seclusion.” That last quotation was written in the first edition of Brown's Manual and is valid to this day. Our representatives will write impressions after the event, not by way of detailed report, but as endeavouring to sum up what, if anything, material has been achieved. The report published by the Association usually gives the papers in extenso, but we wish its issue could be delayed long enough to provide more informative records of the discussions. As the best contributions occasionally come from the floor, the bare‐bones notes of the names of speakers and almost telegram‐like utterances they are supposed to have made, which have been the customary report, could be greatly improved.

Abstract
The objective of this paper is to demonstrate how to use the Elton, Gruber, and Padberg [1978] model to construct optimal portfolios and to facilitate the use of this paradigm by providing an example of how the technique is used. The EGP model uses the risk‐adjusted, excess return for an asset to determine the optimal portfolio for a given risk‐free rate of return. This paper shows exactly how to calculate the optimal portfolio and provides a True Basic@ program to do so. The data used are constructed from Capital International Indexes taken from various issues of Barrons from March 1978 to December 1986.

Abstract
The solder joint reliability of ceramic chip resistors assembled to laminate substrates has been a long time concern for systems exposed to harsh environments. In this work, the thermal cycling reliability of several 2512 chip resistor lead‐free solder joint configurations has been investigated. In an initial study, a comparison has been made between the solder joint reliabilities obtained with components fabricated with both tin‐lead and pure tin solder terminations. In the main portion of the reliability testing, two temperature ranges (−40‐125°C and −40‐150°C) and five different solder alloys have been examined. The investigated solders include the normal eutectic Sn‐Ag‐Cu (SAC) alloy recommended by earlier studies (95.5Sn‐3.8Ag‐0.7Cu), and three variations of the lead‐free ternary SAC alloy that include small quaternary additions of bismuth and indium to enhance fatigue resistance.

Abstract
President Bill Clinton has had many opponents and enemies, most of whom come from the political right wing. Clinton supporters contend that these opponents, throughout the Clinton presidency, systematically have sought to undermine this president with the goal of bringing down his presidency and running him out of office; and that they have sought non‐electoral means to remove him from office, including Travelgate, the death of Deputy White House Counsel Vincent Foster, the Filegate controversy, and the Monica Lewinsky matter. This bibliography identifies these and other means by presenting citations about these individuals and organizations that have opposed Clinton. The bibliography is divided into five sections: General; “The conspiracy stream of conspiracy commerce”, a White House‐produced “report” presenting its view of a right‐wing conspiracy against the Clinton presidency; Funding; Conservative organizations; and Publishing/media. Many of the annotations note the links among these key players.

Abstract
Purpose
To provide an in-depth survey and review of innovation in library and information services (LIS) and to identify future trends in innovative research and its practical application in the field.
Methodology/approach
An in-depth review and summation of relevant literature over the last twenty years, along with an analysis and summary of the other papers in the volume.
Findings
Innovation in library and information work varies between the evolutionary and the discontinuous. A taxonomy of innovatory approaches to development and provision in the sector is provided, along with a detailed listing of the key elements of successful and not-so-successful innovative practice.
Research limitations/implications
The work is dependent on existing literature rather than direct empirical work. However, because it draws together all major aspects of the topic, it has the potential to be used as a springboard for further generic studies and also specific programmes of work.
Practical implications
The need for innovation in LIS will be ever more pressing. The present chapter provides a necessary and rigorous overview of the necessary elements required for success in this area. It will be useful as a reference tool for intending researchers in library and information provision in a wide range of environments.
Originality/value
Because the chapter brings together a substantial body of information on the topic of innovation, it provides a comprehensive study of major developments and likely future trends in the field.

Abstract
It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

Abstract
In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.
