The need to cope with enormous amounts of material has occasionally re
sulted in tile sacrifice of original materials that have been publishe
d, based on the ''rule of thumb'' that once published, these materials
are of less value to a, repository than those materials that are not
published. One of the most famous collections of drawings produced in
the late 1800s. the dinosaur type specimen illustrations of rile O. C.
Marsh Collection, almost fell victim to this practice. This paper chr
onicles the collaborative efforts taken to preserve this historic coll
ection; outlines the integrated approach to preservation that was used
(including a discussion of the various types of surveys, folder lists
, prototypical housing materials and storage, and duplication procedur
es); and discusses how the seemingly contradictory needs of access and
preservation may be resolved through interdisciplinary dialogue.
