Design, Development, and Management of Resources for Digital Library Services

The most important component of a digital library is the digital collection as it holds or has access to viability and extent of usefulness of mustering up the collection of the digital objects and it may include the wide range of the resources i.e. the collections include books, journals, newspapers, maps, printed music, pictures, manuscripts and oral history recordings. This information content may includes the combination of Structured /Unstructured text, numerical data, Scanned images, graphics, audio and video recordings. Thus, the different types of resources need to be mustered differently and the policies must be made accordingly.

Digital objects are more vulnerable to destruction or loss as compared to conventional library materials. Issues like format obsolescence, software obsolescence, hardware obsolescence and storage media fault/deterioration are some of the major threats that make the digital resources vulnerable to destruction. Digital resources require special attention and application of strategies for long term retention and accessibility. The purpose of this paper is to outline the basic issues that threaten the retention and accessibility of digital resources in the long term. The paper also attempts to provide an outlook of the possible solutions for overcoming these issues.

Authenticity is defined as the management of provenance information about the creation of the record. Integrity is defined as the ability to create an authentic copy. Chain of custody tracks all processing done to the record, including migration to new storage systems or to new data encoding formats. Digital preservation addresses the challenge of technology evolution by managing preservation properties independently of the choice of software and hardware systems. Preservation properties include the names used to identify archivists, records, and storage systems, and the preservation metadata which includes provenance information and administrative information about record management. The display and manipulation of digital data is maintained through the use of representation information that describes how the record can be parsed and interpreted. Digital preservation environments implement trustworthiness assessment criteria, enabling verification that the preservation properties are maintained over time. HISTORICAL BACKGROUND The preservation community bases digital preservation upon the same concepts that are used to preserve paper records. The preservation environment manages the authenticity, integrity, and chain of custody of the digital records. At least four approaches have been implemented that define the digital preservation processes and policies that are needed to maintain authenticity and integrity. 1) Diplomatics defines the required provenance information that describes the institution, event, and ingestion information associated with the documentation of an event. Examples of events are treaties and government communiqués. The records are assumed to be held forever. 2) The US National Archives and Records Administration associates records with a life-cycle data requirements guide. Each record is associated with a record group (institution), a record series (the set of records governed by a submission agreement), a file unit, and an entity. Each record series has a defined retention and disposition schedule. The arrangement of the records is governed by the submission order in the record series. Standard preservation processes include appraisal, accession, arrangement, description, preservation, and access. 3) The digital library community manages preservation within the context of a collection, with the required preservation metadata and the arrangement governed by the purpose under which the collection was formed. 4) The continuum model manages records within an active access environment. Records that are generated for one record series may be used as the basis for generating a new record series. The relationships between records within the multiple record series are tracked as part of their provenance. Each of these four communities imposes the preservation processes and preservation policies required to enforce their goals.

The papers fixate on how to preservation of information which is available in digital form and in the printed form, we also discussion on different methods & procedures involved in converting printed form of documents in to a digital form for preservation.

Libraries are storehouse of large number of documentary sources such as records, manuscripts, books, films and other materials. Since these materials with the passage of time are subject to deterioration and decay. Hence all these materials need to be preserved using different mechanisms so that these materials are available to the future generations also. Due to huge advances in information communication technologies (ICTs), there has been an astronomical growth of e-resources -journals, e books, online databases and so on; libraries spend phenomenally on acquisition of these e- resources as these are very popularly used by the students and researchers. Unfortunately, this growth is accompanied by many threats. Digital content (of the e- resources) is fragile and not durable. Its accessibility and use by future generations depends on technology which very rapidly evolves and changes. Hence, ensuring access of e-resources for future generation of users is a big challenge for libraries. This paper discussed the Methods and Technology of digital preservation analysis the various types of preservation in traditional documents as well as preservation of digitized forms of documents using latest technologies.

In this paper, the overall overview of concept of preservation regardless if it is preservation of physical records/archives or digital records/archives is discussed. The concept of the preservation discussed includes preventive preservation, restorative preservation, and content preservation. Then the concept of digital preservation. Furthermore, this paper highlighted the strategies and methods used in implementing the preservation of digital records/archives. The issues those are involved in the digital preservation implementation are also discussed. 2 Overview of the Concept of Preservation According to MS ISO 223-1 (2009), preservation are processes and operations involved in ensuring the technical and intellectual survival of authentic records

Digital information in any form is at risk. Software and hardware become obsolete, and versions and file formats change, making data inaccessible. Data stored in even the simplest form are in danger due to computer media degradation and obsolescence. Online information such as e-journals and databases are susceptible. They may become partially or entirely unreadable, and may not be recoverable by the time the problem is detected. Preservation strategies such as emulation (keeping alive the software and hardware needed to access a digital object), migration (converting the digital object to new versions and formats), and other longterm archival methods have been proposed . Models such as the Open Archival Information System (OAIS) provide an architecture for conducting digital preservation research and experimentation . The importance of preservation metadata has been recognized by a number of groups and efforts to develop and deploy metadata standards are underway .

­ We are living in the digital world. In this digital library environment, the traditional library system and services are being replaced by new techniques such as library automation, collection development of e­resources and networking of libraries. There has been tremendous change in the digital information world. Everyone has to adopt these changes such as printed to digital form. The preservation of digital records in order to identify factors that play a key role in ensuring the long term preservation of the records for better access the information. A digital preservation system is a set of procedures, activities and instruments that help to safeguard digital memory over time. This means to preserve all the documents, both born­digital and converted to digital, in the long term, preserving their content. This paper provides an overview of the major digital preservation activities, definition, concept, process and types of media for preservation. This paper also presents the principles, issues and their strategies for digital preservation. It has also highlights the digital preservation standards and framework fo preservation planning and management.
