On August 6, 1991, Tim Berners-Lee presented the "WorldWideWeb" as a project whose goal is to enable links to be established import any information anywhere. When it comes to libraries, the Web is known as a network-based system to operate and yet a common tool for communication. Early library websites normally contain several documents created in HTML (HyperText Markup Language which is a format based on SGML (Standard Generalized Markup Language). Hypertext is known as an easy way to publish a linking system. It is usually used to inform the schedules and opening hours of a library services and information on how to access the OPAC (Online Public Access Catalogue). by the National Center for Supercomputing Application (NCSA) It has a specification that allows creating HTML content with passion. Additionally, it also has an arrangement to connect external applications to the web. Web is that CGI provides an interactive experience and provides the ability to plug previous applications into the Web. The program was CNIDR's Z39.50 Getaway (Zgate) and an interface called "Webcat" from the University of Waterloo responsible for providing a. Web layer for the library's GEAC system. In 1996, SIRSI introduced a web option for its OPAC, and eventually most other Integrated Library System (ILS) vendors deployed a web interface for the catalog, a class of application universally known as Webcatt655r4r5 . However, web interfaces were not previously a program dependent on the library system and yet they were not the only option for accessing the catalog. System librarians are always called upon to judge the potential of...... middle of paper ....e. System librarians spent a lot of time learning how to manage and extend applications from the library vendor's development team. Therefore, system librarians will maintain specialized software for the library user community. The integration of technical services does not mean that libraries will continue to have exclusive automation needs. Additionally, the Web encourages technologies in managing a problem. The Web has changed the role of the systems librarian from managing a multitude of technologies to managing a wide range of widely used technologies. The instant gratification that comes from browsing the web and the high level of web design skills have forced system librarians to keep up with the latest trends. The Web has allowed the systems librarian to benefit from an experience closer to that of computer scientists in other organizations by allowing the use of a toolbox..
