The study canvassed the concept of digital marketing of library products and services among librarians in selected engineering colleges of Karnataka. This study investigated the existence of the concept of digital marketing in selected engineering college libraries as well as the benefits derived from the digital marketing of library products and services. The study was administered to 100 librarians in four engineering colleges of Karnataka, out of which 65 librarians responded. An item-by-item analysis of the result was carried out by means of a table and a simple percentage of respondents' scores. The result indicated that the majority of the 65 librarians who completed and returned the questionnaire had a positive attitude towards digital marketing/pricing of the library, information, and knowledge products and services and are also aware of the numerous benefits of digital marketing in the digital age. Based on the
result of the survey, it was concluded that certain information products and services can be marketed/priced and that the age-long practice of giving all manner of library, information
and knowledge services free of charge should be reconsidered.
