A primary focus of the physical treatment program at the New York Public Library Conservation Lab has been the continual development of interventive treatment techniques designed to meet the specific preservation requirements of artifactual material which balance both condition and structural factors and ethical considerations. the objective of the procedures is to retain as many of the original components of the item as possible while restricting the degree of physical alteration by minimizing the incorporation of repair material. an overview of the principal operational elements which for the program is outlined below.
The New York Public Library Preservation Database is a comprehensive specification and processing software application developed by Marc Reeves and Errol Somay which has been in operation at the Preservation Division since 1988. 1 the database serves as a nexus for all physical treatment procedures and contains more than 108,000 records documenting individual item and project condition assessment, specification, treatment operations, and time and materials costs. the software system includes various forms of documentation: bibliographical information, survey spreadsheets, testing results, textual and illustrative recording of material and structural features, and protective enclosure manufacture. Each workflow processing step is integrated, from the survey phase through treatment to the return of the item to service. the modular design provides a customized interface for each treatment option, coordinating resource allocation and item tracking, and generating and maintaining all associated documentation records.
A unique aspect of the automated system is that the structure of module is derived from the categories of physical treatment procedures. There is a main bibliographic workform with search capabilities which allows for the importation of MARC records or scanned catalog cards. A complete spectrum of treatment procedures for all formats of library and archival materials is delineated; the options can be expanded, modified and updated. Treatment descriptors are accessible from a pull-down menu. the module operations used for the processing of artifactual material are listed below:
The most recent development in connection with the Preservation Database has been the incorporation of LabTechnique, an on-line graphically-oriented training manual, into the database itself. the multimedia manual serves as an visual reference guide which defines specification terminology and treatment options for non-treatment staff within the institution; more importantly it functions as a digital training tool, explicating standardized physical treatment procedures for artifactual material in a variety of formats, substrates and media: books, manuscripts, prints, drawings, maps, photographs and posters.
The inclusion of a variety of interventive treatment techniques has been a principal design objective of the manual. Digitized film-based documentation, including standard slide formats and photomicrographs, and most recently, video-imaging, will provide the visual background for each segment of the multimedia presentation. the effects of various examination and treatment operations can be defined, recorded, modified and expanded because of the flexibility of the format. One addition to the overall scheme of the manual interface is the incorporation of relevant information pertaining to historical manufacturing and restoration practices. the segments of the manual currently in production are listed below:
Items in codex format can be considered to be the most vulnerable type of artifacts since in an institutional setting it is often difficult or impractical to divorce this type of material from the utilitarian role which still remains a primary attribute. the preoccupation with functional considerations often leads to the justification for extensive alterations in construction. the binding is often considered to be a disposable component, not an integral part of a composite structure that can be characterized as a product of human workmanship. the basic precepts of artifactual conservation for codex format are as yet undetermined and one of the most important responsibilities of the conservator is to promote both an awareness of and appreciation for the methods of fabrication of this type of object.
The relationship between the physical condition of the item and the acceptable degree of alteration has to be defined. This step is of particular importance when dealing with bookbindings where structural concerns related to poor construction practices have to be taken into account as well as problems associated with deterioration and the use of poor quality material. the sequence of operations undertaken during the specification process are listed below:
Both the particular format and the extent of documentation are determined by the artifactual significance and the treatment specification of individual or groups of items. the information record is quite flexible in configuration; the level of documentation required will vary depending on the artifactual significance and physical condition of the material. It is especially important to document damaged components prior to any treatment procedure involving any degree of modification or alteration. the visual record provided by photodocumentation has proven to be the most objective and accurate record. Individual treatment records consist of the following elements (fig. 1):
It is essential that the repair techniques be adaptable, not rigid imposed solutions. in addition to the tools traditionally associated with treatment repair operations other types of tools and equipment have proved to be quite useful in manipulating weakened or damaged materials: synthetic fan brushes, deerfoot brushes, cleanroom swabs, flexible Teflon spatulas, Teflon folders, self-adherent wrap and syringes.
