Selection of the appropriate authoring software and file formats depends on what is the in-house team expertise, what are the demands of the title being developed and what are the available funds for this purpose.
It can be defined as the specific message, data facts or information to be presented. The content specialist provides the content to the multimedia architect, who in turn prepares the narration, text bullets, charts and tables etc. Activities in this phase include- content research, interface design, graphics development, selection of musical background and sound recording, development of computer animation, production of digital video, authoring, etc.
Video clips can also be shot, digitized, edited and compressed. Navigational elements like graphics button can be created or already available buttons can be used. A pilot project will be prepared at that time. While testing, each and every aspect for smooth running of the program is to be taken care of.
If the product is a website, it should be uploaded on the web to test its functioning on different browsers e. Internet Explorer and Netscape Navigator. If it is a multimedia application on a LAN or Internet, it must be put on the server for testing purpose. After the tests are over the product should be revised, to incorporate the valid changes suggested.
Contact details and e-mail address along with phone number should be provided for technical support and also for sending comments and suggestions. The other effective way is on Internet website. Now multimedia content is being widely disseminated through Internet.
Although bandwidth problems, requirement of a number of plug-ins to play video and audio, long download time and other problems exist that hamper the delivery of multimedia application through Internet. The application can be continuously updated and the content does not get outdated on the internet, while on CD-ROM continuous updation is not possible. Vice-versa, if the application is developed and uploaded on the website where information keeps accumulating, then as the archive becomes substantial it can be reproduced on a CD-ROM for convenience viewing.
Because of some copyright problem, if the multimedia product cannot be delivered through Internet it can run over a LAN or Intranet.
The production of fine quality high-end multimedia application require a specialize team consisting of the following members Vaughan, He is the person responsible for the quality and timely production of the application.

Following is a brief account of application of multimedia technology in libraries.
Rowley, In case of libraries improving accessibility to both collections and services has always been a concern. Kiosk is designed for libraries usually located near the entrance of the library, used for displaying announcements, reading lists, comments and suggestions from library users, and other information concerning library operations and programs. Library collection, catalogue, archives, services and location of those collections, responsible persons of various library services showing the floor layouts are graphically represented in a library kiosk.
Videoconferencing is conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data.
