Tools, techniques and protocols necessary for building up digital libraries have now fully evolved with computing power that allows parallel processing, multitasking, parallel consultation and parallel knowledge navigation and sohare tools that facilitate artificial intelligence and interadivity. Coincided with availability of sofhvare, hardware and networking technology, the advent of world wide web 0its, ever incr easing usage and highly evolved browsers have paved the way for creation of digital libraries. With rapid developments in technologies necessary for developing digital libraries, the world of digital information resources has expanded rapidly and exponentially. Increasing number of publishers are using the internet as a global way to offer their publications to the international community of scientists and technologists. With the technology available at an effordable cost, the libraries are initiating small digitisation projects as an individual library or as a group of libraries. Building-up digital collection and the infrastructure required to access them is a challenge that every library has to deal with. The article delves into technological evolution, cultural revolution and contents enrichment that led to revolution in growth and development of digital libraries. The artide has two distinct parts, while the first part deals with various aspects of building, accessing and organising digital resources and collection, the second part elaborates on the process, technology, formats, compression techniques and tools used in digital imaging. The article describes optical character recognition (OCR) and advocates for hybrid solution for preservation of digital information. http://dx.doi.org/10.14429/dbit.21.6.3547
