Guide to the Research Collections
This subject is more than adequately covered; the preceding observations on types of materials present are applicable here. Periodicals have been discussed above; the publications of forestry organizations and the reports of national and state bureaus of forestry are substantial, particularly for the United States. Approximately 550 entries under the heading "Natural Resources--Conservation" refer to government publications, including conservation laws of the states of the United States. There are also reports of national and international congresses on conservation and publications of the associations and organizations concerned with the subject.
The Local History and Genealogy Division has not only pictorial material on United States national parks in its archives of photographs, stereopticon views, and scrapbooks, but also regularly receives ephemeral material which is stored in vertical files. Ephemera from state parks in the United States is also available, although on a more limited basis. As a matter of course commercially published materials augment this ephemera on state and national parks.
