“Part iii, line 1a: the collection of historical documents is held for educational, research,and curatorial purposes. It is continuously cataloged, preserved, and cared for. The items in the collection, which were acquired through purchases and contributions since the society's inception, are not recognized as assets because they have no alternative uses. Purchases of collection items are recorded as decreases in unrestricted net assets in the period in which the items are acquired or as temporarily or permanently restricted net assets if they are purchased with donor-restricted funds. Contributed collection items are not reflected on the financial statements. Proceeds, if any, from the disposition of collection items are reflected as increases in the appropriate net asset classes. Part iii, line 4: the collection of historical documents is held for educational, research, and curatorial purposes. Part v, line 4: the intended use of the organization's permanent endowment funds is to continue the programs of the organization.”
