Since 1953 the Clements Library has broadened its coverage of American history from 1493 down to the 1850s and acquired some notable manuscripts and maps as well as some remarkable rare books. Although 16th-and 17th-century books on the New World rapidly grew scarcer in the last two decades, the Library made a determined effort to pick up all those that could be afforded, but the total was only 265. Eighteenth-century books were eagerly acquired on a selective basis as offered (1,850 altogether) but not surprisingly it was in the first half of the 19th century that most opportunities for purchases occurred: some 4,800 titles.
Significant additions were made to the period of discovery and settlement, Indian affairs, and the growth of the colonies in the West Indies, Canada, and the modern United States. The Library's impressive American Revolution collection was enlarged, as well as the collections on the Old Northwest and the Southwest after the Revolution. The Library filled out its War of 1812 holdings, then greatly expanded its materials on the various reform movements that burgeoned after 1815 — antislavery, women's rights, prison reform, pacifism, and temperance. Associate James Shearer II ('08e) of Chicago made possible the acquisition of many overland and Gold Rush narratives of the 1830s, '40s, and '50s. The Director developed the Library's holdings of short-lived periodicals of the late 18th and early 19th centuries, sought more early novels and plays, formed a collection of early architecture and furniture design books, pushed the addition of music material, and initiated collections on four indigenous religious sects: the Shakers, Mormons, Adventists, and Spiritualists.
To combat the inflation in prices of such materials in the 1950s and '60s, University support was slowly increased, a large bequest has given timely support, and the Clements Library Associates have outdone themselves in raising funds. The dispersal at auction, 1966-69, of the Americana library of Thomas W. Streeter of New Jersey rallied the Associates into a tremendous campaign that coincided with the University's Sesquicentennial observance. The Associates were able to raise a total of
