| Abstract | In any modern desktop environment the glyph compositor-where raw text information is combined with font information and other attributes to render rasterized component images-is part of the software's core functionality. In this paper we present work that shows it is computationally feasible to apply full-text indexing in real-time to the live stream of glyph compositor operations generated by a user's interaction with their desktop environment. By embedding indexing functionality at such a level, we effectively get to “see” (and more importantly remember) all the text that is drawn on the user's screen. With elements reminiscent of the Memex, we illustrate the technique in use through a personal digital library we have developed that enriches (through text-searching and context) the user's desktop experience by letting them go back in time to view information that had previously been displayed. We achieved this by augmenting our dynamically updated text index with time-stamped snapshots of the desktop. By recording the (x, y) positions of the text at the time it is rendered, the snapshots have a semi-live feel, whereby text can be selected for copy-and-paste operations for further use. Moreover, windows-even if they were hidden behind others at the time the text was rendered-can be brought to the front and their text accessed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
