The present paper reflects the gradual change in the need and use of the marketing concepts in libraries and information centres (LICs) and its fruitful effects in the service to the library users, and studies marketing of information products/services in LICs of R&D institutions of Council of Scientific & Industrial Research (CSIR) of India. The paper discusses the role of these LICs including marketing approach, need and application of a marketing program with the help of a survey. For the survey, data were collected through a detailed mailed questionnaire along with interviews. The findings reveal that librarians have a positive attitude towards the different aspects of marketing of a library's information products/services. The study recommends that currently efforts for increasing user-awareness and separate financial support are requisite for efficient marketing. Instead of scattered approaches and different styles, a coherent view must be taken This paper attempts to model the marketing and sales process of high-tech start-up companies. It correlates the notions of the marketing mix (the 4Ps) with the probabilities of success of various phases in the sales process. By applying the formalism of reliability block diagrams used in engineering, the total probability of the sales process can be expressed as a function of the probabilities of all the subprocesses. A particular insight resulting from this work is that the total probability of the customer buying decision corresponds to the relative market share of the company. Discussing the allocation of investment in the specific marketing elements of this model will improve understanding of how management can achieve a rapid increase in sales and so accelerate the development of a high-tech start-up company.
