DESIGN AND IMPLEMENTATION OF A DIGITAL LIBRARY SYSTEM
Libraries have been an important part of educational and information sector of any school. The success of any library largely depends on proper management.
Several libraries have suffered failure as a result of inadequate management and incapacitations in handling sensitive information as regards members of the library.
This research therefore, aimed at developing a digital library system, which will help direct and position library to meets its ever increasing demands.
In the course of the development of this new system, the current system was analytically and critically studied or assessed and thus the identified strengths and weaknesses were highlighted and a new system was designed for the weakness.
The present system was analyzed using a standard procedure recognized worldwide for such purpose and this is called Structured System Analysis and Design Methodology (SSADM). The visual basic 6.0 programming language was used to code the program modules developed for the system using some computer aided design tools.

Digital Library System (DLS) extends and integrate approaches adopted in traditional libraries as well as in distributed information systems, to yield high-end information systems, services and institutions. Here we will explore some of the parts or components of digital libraries and discuss several of the developments in this emerging field.
Building a comprehensive digital library system will help users to manage all phases of the information lifecycle. Of particular importance is to simplify the authoring and creation process so that wider population can participate by adding all types of multimedia content directly into digital libraries. Downstream access allows readers to benefit from this type of computer-mediated communication, across time and space. Ultimately, it is believed that knowledge will be shared and then lead to yet another cycle of discovery, authoring and utilization that is facilitated by digital libraries.
1.1 BACKGROUND OF THE STUDY
Times are fast changing; we now live in a jet age which is mainly characterized by rapid changes in technology, lifestyle and value. This is indeed an age of information explosion.
One of the major inventions that have driven the world to a fast pace of technological advancement is the computer. The computer is primarily an electronic information processor that is rapidly changing the way we acquire, organize, recall, access, analyze, synthesize and apply information. The effectiveness with which the information is generated and communicated determines the rate of progress of a society and the fulfillment of its people. Modern society is information driven and information today is a universal need.
Moreover, computers have affected the ways which people use information. It has changed the rate of work done, the method for accomplishing the work alongside the relationship among the people carrying and using the information. However, computers and libraries are not left out in the utilization of computer to carry out their day-to-day activities especially as it concerns the amount of information generated. Libraries have evolved over the years which gave rise to digital libraries.
1.2 STATEMENT OF THE PROBLEM
There are numerous problems with the traditional libraries. These in-adequacies are enumerated below.
1. The users of the traditional library need to go the library physically which most times could lead to congestion of the library?
2. Inability for the library resources to be accessed 24/7.
3. The library resources cannot be simultaneously used. It is one at a time.
4. Traditional libraries are limited by storage space.
1.3 GENERAL OBJECTIVES OF THE STUDY
The proposed system Digital Library System has it’s general objectives which it is set out to achieve. They are as follows:
a) To create variety of access services for searching, browsing and discovering resources.
b) To organize and index digital objectives for different purpose which includes cataloging, finding aids and database.
c) Reduction of loan and acquisition through the use of digital library.
d) Comprehensive storage of large repository of data that can be accessed by authorized users.
e) Reduce the cost of maintaining a traditional library.
1.4 SPECIFIC OBJECTIVE OF THE STUDY
The objectives of this proposed system has been narrowed. This is geared towards ensuring that the objectives are achieved. They are as follows:
⦁ Removal of Physical Bounding: Ensure that the users do not always go to the library physically, but can access library resource once he/she is connected to the server.
⦁ Round the Clock Availability: To enable users to be able to gain access 24/7 to the information.
⦁ Information Retrieval: To make it easy and convenient for the user to use any search term (Title OR Authors name) to search the entire collection, thus providing user-friendly interfaces, and giving clickable access to it’s resource.
⦁ Preservation and Conservation: Provide access to materials that would otherwise fall to degradation from repeated use.
⦁ Multiple Access: Ensure that the same resources can be used simultaneously by a number of persons.
⦁ Space: Able to provide storage for information digitally by using little physical space to contain them.
1.5 SIGNIFICANCE OF THE STUDY
In implementing the objectives of this study, the advantages of a digital library over the traditional library are enormous. Users will be able to access library resource digitally without the inconveniences of users carrying books, journals, magazines etc which could result in rapid wear and tear of this library resource. Besides, it will afford users the opportunity to access digital books simultaneously without waiting for the book to be returned to the library.
The proposed system will provide security to help track library resources through the development of a comprehensive database that will be used to house the library resources. The system will also eliminate some of the routine manual work prevalent in a traditional library.
1.6 SCOPE OF THE STUDY
The findings of this research work for the proposed system (Digital Library System) was carried out in the Nnamdi Azikiwe University (NAU) in their digital library section. The scope of this study will include the following:
1. Information indexing/cataloguing.
2. Classification of library resource.
3. Searching and retrieval (downloading).
4. Registration of books/uploading of digital resources
5. Registration of users.
6. Database management.
1.7 LIMITATION OF THE STUDY
This proposed system will not take into consideration audio collections. It is web based not a stand alone delivery system with its own user file and login ID and password. Also, time constraint during the time for this project work is short. Financial resources is a limitation encountered in the course of this research work.

With the expansion of the World Wide Web, the topic of digital libraries has become more and more important. Some scholars has numerous contribution and research work targeted at making the topic digital library system an educational tool which will help drive learning and academic research to its grass-root.
The research and development of digital libraries are no easy task. They involve a large number of topics in library, information and computer sciences such as information indexing, retrieval, collection development, database management, reference services, human-computer interaction, interface design, digitalization and preservation, intellectual property, networking and interoperability.
2.1 EARLY STAGE OF DIGITAL LIBRARY
The first digital library that came into existence was Project Gutanberg (PG). Project Gutenberg is a volunteer effort to digitize and archive cultural works, to encourage the creation and distribution of electronic books (Har, Michael, 2004). Most of the items in PG collections are full text of public domain books. The project tried to make these resources as free as possible in a form that can be downloaded and used by any computer.
However, the emergence and development of digital libraries at this stage are driven by two main forces. First, digital technological development, especially in multimedia and networking, offered more-efficient and sometimes new ways in information processing and management. Secondly, people wanted to better share important information like library materials, scientific in educational and research materials.
Most early “digital libraries” were various types of digital collection and information system. Personal information resources, workgroup and organizational information collections and collaboration environment are some examples. Edward Fox in his book “Digital Libraries Overview” offered a detected account of some early projects in the field. According to his timeline, electronic thesis started as early as 1987 (Edward Fox, 1992). Libraries were also working towards this direction. Many libraries started to replace their card catalogue with OPAC systems, and were beginning to store abstracts and periodicals on CD-ROMs.
In 1989, the World Wide Web project was first proposed and since mid 1993, it quickly grew at an exponential rate. User could browse and set up a node on the network to use information on it. It was called by some people the beginning of a true digital library. But the web is a library without a card catalog, and many search tools or services were crude at the early stage..
