Charging or Issues Systems in Special Libraries in Sierra Leone

Introduction
Special libraries are collections that exist to serve the specific needs of their clients. The libraries are varied as their needs. However, the libraries do have common elements in the service that they provide, their focused collections and their knowledgeable staff who are able to adapt to the changing needs of their clients base. The phrase “Special libraries” is a misnomer, because all libraries are special and have commonalities in their functions. This statement does not dispute the fact that some libraries have special concerns-be they of their clientele, their collections or their purpose. A standard definition of a special library would be the one that exist to serve the limited needs of a specific entity- a business, industry, government agency, non-profit group or professional organisations. Also included are subject oriented units of a public or academic library (Beenham and Harrison, 1990).

The collection of special libraries is smaller and tends to be more focused in comparison to public and academic libraries. Special libraries have the tools and the people necessary to make information available to the client because it is not just enough to collect and house information. It christopher hsu must be made accessible to users. A Special library in short is particularised information services which correlates, interprets and utilizes the materials at hand for the constant use and benefit of the organisation it serves (Chirgwin and Oldfield, 1982).

The over-riding requirement of the Special library is that it should provide current information that enables research workers and other employers to carry out their duties effectively. Therefore, it provides not only a collection of materials for which is known demand, but also a network of services that make information readily available for a variety of outside sources.

Previously, the provision of books and other materials for purposes of research had been considered of paramount importance. With the dramatic increase in the number of post-war student in Sierra Leone, it came to be more generally accepted that a university library should aim to serve the needs of their main categories of readers; namely, the undergraduate research worker, and the academic staff.

Definition of Charging or Issues System

According to Berkett and Ritiche (1977), the recording of the loan of materials is called charging or issuing. The charging method selected by a particular library depends to a large extent on the library’s clientele, the size of the stock and the need to restrict the number of items which a library member may have on loan, and on whether the library has peak periods for the lending and returning of materials. The choice of methods will also be affected by the amount and type of information the library staff requires the issue to furnish.

The purpose of a circulation system is to give the library users as much access as possible to the stock. Unfortunately, a book loaned to one reader is not available to others and certain restrictions have to be made. For instance an Encyclopedia is a compendium of knowledge on a vast number of subjects and is designed for easy reference rather than for continuous reading. Allowing such a book on loan would inconvenience a great number of library users without benefitting the borrower.
Each library will use a system for recording the books and other items it lends to its readers. There have been many modern developments to record issues in the last thirty years, mainly due to high cost of staffing, increased usage, and in search of better all-round efficiency. There is no one all-purpose systems which will meet the demands of all kinds of library, although the latest computer charging system can cope with many aspects speedily.
