Lumspecs ( Lesser Used Materials SPECS )
Specifications for the binding of library
materials that are expected to receive little use
and need not, therefore, be bound according to
Class "A" specifications, but which are expected
to be used to the extent that they require greater
protection than that afforded by a pamphlet box.
Essentially, Lumspec binding differs from Class
"A" in three respects: 1) the Lumspec book is side
sewn instead of oversewn or sewn through the
folds; 2) only the spine and a small part of the
sides are covered in buckram, with the remainder
of the boards not being covered at all; and 3) the
volumes are not lettered. The bindings so produced
are called Lumbindings. Lumspecs were devised in
1957 by a subcommittee of the American Library
Association's bookbinding committee and were
approved that same year by the Library Binding
Institute. (11 , 211 )
