Library materials designated by the Library
Binding Institute as being: 1) materials subject
to "normal library usage" that are complete but
which may at some later date be discarded and thus
are not considered to be a permanent part of the
library's collection; and 2) materials not subject
to normal library usage, so little used that
completeness is not a factor of importance, and
not considered to he part of the permanent
collection. For the former category, the L. B. 1.
recommends that such materials be considered
permanent insofar as binding is concerned and
therefore bound according to the L. B. 1.
standards; for the latter, treatment would depend
on the purpose of the library. the physical
condition of the materials, and reader
requirements. Such materials do not require
library binding in accordance with L. B. 1.
standards; however, Certified Library Binders (L.
B. 1. members), will either develop a type of
binding meeting the library's particular
requirements, or hind according to the
specifications for lesser used materials. See:LUMSPECS . (208 )
