For example, the autism Web site also has links to sites dealing with mental retardation, mental health, people with disabilities and social services for children. Third, all of the TRFN pages are very comprehensive and organized by people with a clear understanding of the library sciences. With more than 10,000 pages of information, this is a necessity. Fourth, there are links to many local companies. Because TRFN is sponsored by the Carnegie Library of Pittsburgh, and is not driven by advertising like most other Web sites, it does not have to worry about offending, or having to promote, any particular Web site over another.
Alphabetical order is the rule of the day.
Fifth, one-sentence descriptions on the TRFN site introduce each organization before the user clicks on its link and loads its Web page. The majority of local links are based in Allegheny County, but TRFN is working at expanding. TRFN is based in Oakland, at the main branch of the Carnegie Library. It has been online almost four years.
