    Abstract
    Machine-Readable Cataloging (MARC) is currently the most broadly used bibliographic standard for encoding and exchanging bibliographic data. However, MARC may not fully support representation of the dynamic nature and semantics of digital resources because of its rigid and single-layered linear structure. The Functional Requirements for Bibliographic Records (FRBR) model, which is designed to overcome the problems of MARC, does not provide sufficient data elements and adopts a predetermined hierarchy. A flexible structure for bibliographic data with detailed data elements is needed. Integrating MARC format with the hierarchical structure of FRBR is one approach to meet this need. The purpose of this research is to propose an approach that can facilitate interoperability between MARC and FRBR by providing a conceptual structure that can function as a mediator between MARC data elements and FRBR attributes.

    Abstract
    Colon Classification (CC) is truly the first freely faceted scheme for library classification devised and propagated by Dr. S.R. Ranganathan. The scheme is being taught in theory and practice to the students in most of the LIS schools in India and abroad also. Many manuals, Guide books and Introductory works have been published on CC in the past. But the present work tread a new path in presenting CC to the student, teaching and professional community. The present work Colon Classification: Theory and Practice; A Self Instructional Manual is the result of author's twenty-five years experience of teaching theory and practice of CC to the students of LIS. For the first ime concerted and systematic attempt has been made to present theory and practice of CC in self-instructional mode, keeping in view the requirements of students learners of Open Universities/ Distance Education Institutions in particular. The other singificant and novel features introduced in this manual are: Presenting the scope of each block consisting certain units bollowed by objectives, introduction, sections, sub-sections, self check exercises, glossary and assignment of each unit. It is hoped that all these features will help the users/readers of this manual to understand and grasp quickly, the intricacies involved in theory and practice of CC(6th Edition). The manual is presented in three blocks and twelve units.

    Abstract
    This book, based on the class room teaching experience, has been divided into thee parts deemed convenient to the student community to wich it is primarily adressed. Part-I ,the most important discusses about the Rules, Facet Formulae, Subject Analysis, etc. To tell the users as to from where the isolates in each Facet are to be obtained. Each rules of CC-6 is explained with suitable examples in order to make it understandable. Another feature of this manual is that "Solved Examples" follow the discussion for evry Main Class included in CC-6. To provided the students with the opportunity for practice, an "Exercise for Practic" has been added in each Chapter. This book includes about one thousand solved examples for practice, answers to which have ben provided at the end. The basic theoritical concept of CC-6 required essentially to understand the rules, have been explained in part-II.It includes such topics as Fundamental Categories, common Isolates Devices, Phase Relation, among othor, and are suitably illustrated. Efforts have been made to clarify the concepts in simple language with a view to understand the Indian scheme, cnsidered one of the scientific classification system in the world.

    Abstract
    This review describes experimental designs (users, search tasks, measures, etc.) used by 31 controlled user studies of information visualization (IV) tools for textual information retrieval (IR) and a meta-analysis of the reported statistical effects. Comparable experimental designs allow research designers to compare their results with other reports, and support the development of experimentally verified design guidelines concerning which IV techniques are better suited to which types of IR tasks. The studies generally use a within-subject design with 15 or more undergraduate students performing browsing to known-item tasks on sets of at least 1,000 full-text articles or Web pages on topics of general interest/news. Results of the meta-analysis (N = 8) showed no significant effects of the IV tool as compared with a text-only equivalent, but the set shows great variability suggesting an inadequate basis of comparison. Experimental design recommendations are provided which would support comparison of existing IV tools for IR usability testing.

    Abstract
    Presents a state of the art review of the literature of expert systems in library and information science, involving exhaustive searches of all major LIS CD-ROM databases (LISA, ERIC, LiLi, INSPEC etc.) and bibliographies appended in review articles. The search retrieved 679 references, comprising 362 periodical articles, 180 conference proceedings, 63 books articles, 28 theses and 46 monographs. The growth of the literature peaked between 1989 and 1990 and subsequently declined after 1992. Over 1/3 (287) covered intelligent front ends and interfaces for online searching and retrieval, followed by applications in reference service (113), classification, indexing and abstracting (86) and cataloguing (7). The most productive periodicals comprised 6 titles, of which 'Information processing and management' topped the lsit: 43 authors were found to contribute between 5 and 35 articles each, hence contributing 32,19% of the total contributors. 382 of the publications were single author works, 172 were by 2 authors, 72 were by 3 authors and 49 were by 4 or more authors. Only 161 titles were expressive enough to reveal both the name and function of systems being developed

    Abstract
    Videogames are important cultural and economic artifacts. They also present challenges that anticipate the problems inherent in any complex digital interactive system. Not only are they digital and hence very difficult to preserve but they also are software systems that have significant hardware, peripheral, and network dependencies, which are difficult to collect and formally represent. This article reviews the literature related to videogame preservation. In addition to covering the traditional technology-related issues inherent in all digital preservation endeavors, this review also attempts to describe the complexities and relationships between the traditional acts of technology preservation, representation, and collection development. Future work should include the identification of important user groups, an examination of games' context of use, and the development of representational models to describe interaction of players with the game and the interactions between players playing the game.
