Purpose: The purpose of this study was to investigate the specific categories of documents and also evaluate using the five WH questions for achieving the plan and method of dissertation classification. To this end, were used bibliographic and metadata elements organizing dissertations as categories to answer WH questions.
Methodology: Two methods of library and comparative survey were used in this research.
Findings: Documentation review showed that many librarians have introduced new categories to organize their collections. Samples of these classifications were provided for a variety of information resource formats including music resources, archival resources, museum and art objects, maps, patent, periodicals, and more. Various designs have also been presented for different genres and subject areas, including literary, story and laws.
Based on this research, 22 categories were identified to answer the five WH questions including 9 categories for answering the Who? question, 7 categories for answering the What? question and 2 categories for answering Where?, When? and Why? questions. Categories were compared with metadata and bibliographic elements, blocks, and descriptive areas. As a result, the UNIMARC blocks and fields used to classify dissertations include 32 fields and 4 blocks include descriptive information, notes, subject analysis and the responsibility of the work
