<p>A study of the tree structures developed by Finkel and Bentley (3 & 4) was done and the results are documented in this report. These tree structures, i.e. the quad tree and the k-d tree, were especially developed for associative retrieval. A comparison of the above tree structures and the well known binary search tree is presented for exact match queries.</p> <p>An implementation of the insertion algorithms for each tree structure and a generalization of Aldon Walker's (9) display algorithm are given.</p> / Doctor of Philosophy (PhD)

This study examines the collection development policies and procedures of the independent Black schools that belong to the Council of Independent Black Institutions. The primary focus is on, 1) the types of sources used to select and acquire library materials pertaining to the Black experience, and 2) the extent to which the collections of the schools focus on materials documenting Black life and culture. Major findings include, that in the Black independent schools surveyed, 1) Black book stores are the major source of library materials concerning Black life and culture, and 2) in terms of abundance, materials concerning Black people are the most important part of the library collections. This report suggests the need for further research to explore dimensions of resource development in Black schools beyond the scope of the present investigation.
