TL;DR: An overview of systems methodologies is offered starting with the traditional approach and considering structured hard methodologies and soft methodologies, and the applicability of existing system methodologies for library systems is reviewed.
Abstract: An organised systems analysis and design project is essential to a successful systems implementation. Systems methodologies have been developed to encourage a system atic approach to information systems planning, analysis and design. This article offers a bnef overview of systems method ologies starting with the traditional approach and considering structured hard methodologies and soft methodologies. Methodologies offer a series of phases and steps through which a project must proceed and a series of tools and techniques to assist in analysis and design. They are particu larly appropriate for detailed design of software, databases and hardware configurations. Library and information man agers rarely engage in fundamental systems design. Increas ingly, the library and information manager is not designing a system, but rather selecting the most appropnate system or software package and then tailoring a hardware configuration and a system to a specific application. This is a role that managers in other areas will also increasingly encounter.
This overmew reviews the applicability of existing informa tion systems methodologies for library systems.

TL;DR: The pricing tariffs adopted by the online hosts are full of hidden complexities, such that it is difficult to estimate in advance the cost of online searching, and the review offers an insight into the estimation of the costs.
Abstract: The pricing tariffs adopted by the online hosts are full of hidden complexities, such that it is difficult to estimate in advance the cost of online searching. Potential elements of costs are: subscription charges and discount plans, connect time charges, display/print charges, telecommunications charges, session rates, charges for special facilities and charges for special services. The complexities of each of these elements are considered in relation to a number of online hosts. The review offers an insight into the estimation of the costs of online searching.
