Libraries are defined as institutions existing to provide reading materials and educational enlightenment. Public libraries offer free access to books, films, music, digital books, reference materials, study areas and other resources. Specialized libraries, such as law and medical libraries, cater to specific groups with concentrated materials. Modern libraries also include computer terminals for online research and use.
Resource centers can exist independent of a library. For example, teacher resource centers provide multimedia tools such as computers, video equipment, laminating machines, copiers, and art supplies. Educators can craft visual displays, develop lesson plans and polish instructional designs in a teacher's resource center.
Combined public library and resource centers intertwine traditional library offerings with enhanced public services. Books and printed materials are linked in the same buildings with resources for faxing, Internet connectivity, and even things such as notary public services.
Some libraries are linked to resource centers for highly specialized purposes. For example, the State of Virginia has a library for the visually impaired. It includes such things as braille reading materials and audio books. The library also offers extended specialized services such as Braille note-takers, software for the visually impaired, folding canes and Braille paper.
