It can support teaching through online full text reserves and other means. And it can support public service through allowing the general public to access its online resources, including the online public access catalog. Public library Web sites serve different purposes. A typical public library might want to provide free and open access to information for all local residents, and this could be reflected in the library Web site through links to community information resources, links to job postings, access to the library's online catalog, etc. While a public library might want to give completely free access to its Web resources, licensing restrictions on some electronic databases may limit this scenario.
Special libraries have still another mission when it comes to creating a Web site.
Special libraries generally need to service their parent company or organization, and the library Web site will reflect this through focusing almost exclusively on the parent company's staff and clientele. Generally, however, the special library Web site will be an internal tool that will focus almost exclusively on staff. How mission impacts the content of a Web site Mission clearly has an impact on the content of any Web site. An advertizing agency Web site will look quite different than a library Web site, even though each may be fulfilling its own mission. As mentioned earlier, the type of library will affect the nature and content of the Web site.
