Still, the importance of cataloging the collections cannot be overstated. If an item is not in the catalog, it cannot be found efficiently. If it cannot be found, it might as well not be in the collection. There have been several initiatives to catalog, assess, or rehouse the Society's various library and museum collections over the years, and in each case, there have been numerous "discoveries" of valuable items. In 1985, for example, a gilded chair made for Louis XVI and given to Marie Antoinette was discovered in a Society warehouse. Without a comprehensive catalog, there are bound to remain many such items in this state of "nonexistence." Developing a single up-to-date inventory of the collections will remain a long-range project requiring perpetual investment for the foreseeable future.
Another consequence of the historical lack of a collections management policy is that the Society now owns a collection without clear geographical, chronological, or thematic boundaries. Redefining those boundaries after materials are received is extremely difficult. Reasonable people will inevitably disagree on the proper delineation of the boundaries. Debate on whether the Society's updated mission statement ought to include colonial materials not directly related to the New York region, such as the Philadelphia printing of the Declaration of Independence, offers a case in point. Furthermore, even if such decisions could be made, deaccessioning collections has legal ramifications. If a donor stipulated that an item was to be held by the Society in perpetuity, breaking that restriction requires legal action by the state attorney general and the courts—another expensive and time-consuming process.
Conservation and preservation
At the core of the Society's mission is its responsibility for the millions of items under its care. As one would expect, the Society's most valuable holdings are very old and therefore extremely fragile. Letters and manuscripts were written on paper that will inevitably turn to dust; books were bound with materials and glue that deteriorate; and pictures were created with paints that fade, on canvases that disintegrate. Thus even if elaborate preservation technologies had been available from the Society's earliest days and the Society had actively managed a conservation program, a constant and never-ending portion of the Society's resources would still have to be directed toward the physical maintenance of the collections.
Unfortunately, for much of its history, the Society did little to protect its valuable holdings from the effects of time. The rapid growth of the collections, the lack of resources, and the limited preservation tools available in the early years are all factors that contributed to this neglect. Consequently, a substantial quantity of paintings, manuscripts, drawings, and books are in need of immediate attention. The creation of the painting and paper conservation labs during the late 1980s was an important step forward in addressing this problem, and much progress has been made, but like cataloging, conservation and preservation are unremitting obligations.
