Many elementary schools tend to view library as another "specials subject" like art, music and P.E., and they schedule it on a fixed basis. What this means is that at a certain time each week, children in each class will visit the library unaccompanied by their teacher, while the media specialist teaches some type of lesson that may or may not have anything to do with literature, library resources or the curriculum. While this does at least get the children into the library, the main benefit of this type of scheduling is to allow the teacher a planning period and does not make best use of the library or what is has to offer. The truth of the matter is, a library is a resource, not a subject, and all of its materials, in addition to the skills of the trained library media specialist, are best accessed on an as-needed basis by teachers as well as students.
