AID Classification Scheme and Alphabetical Index

The scheme consists of two main components: the classification scheme itself and the alphabetical index. The classification scheme is divided into 18 categories, each represented by a single upper-case letter. These categories include Agriculture, Communications, Culture, Economics, Education, Energy, Food and Nutrition, Government and Law, Health, Human Settlements, Industry & Technology, Labor, Management, Natural Resources & the Environment, Population & Demography, Sciences, Sociology & Psychology, and Transportation. Each main category is further broken down into more specific subcategories, denoted by letters and numbers following the initial letter. For example, the Agriculture category is divided into subcategories such as A02.2 (Animal products) and A02.25 (Draft Animal). The classification scheme is designed to provide a consistent and organized way of arranging documents on the shelf, allowing users to easily locate related materials. The alphabetical index is a companion to the classification scheme, providing a list of terms and their corresponding notations. The index is intended to be used as a finding tool for the classification scheme, allowing users to quickly locate the notation for a particular term. However, the index should not be used alone, as it may not provide the full context of the classification scheme. One of the key challenges in using the classification scheme is determining which subject to choose for a particular document. The scheme suggests several guidelines for making this decision, including trying to be consistent, developing rules for choosing the most specific subject, and considering the importance of the subject to the users. However, the scheme also acknowledges that classification is an art, not a science, and that different catalogers may treat the same document in different ways. The AID Classification Scheme is based on the AID Thesaurus, but it is designed to be more concise and easier to use for shelf organization. The scheme is intended to be used in conjunction with the AID Thesaurus, which is used for indexing documents on a database or in a card catalog. The polyhierarchy of the AID Thesaurus makes it unsuitable for shelf organization, but it provides a more detailed and comprehensive list of terms for indexing purposes. The major categories in the AID Classification Scheme are Agriculture, Communications, Culture, Economics, Education, Energy, Food and Nutrition, Government and Law, Health, Human Settlements, Industry & Technology, Labor, Management, Natural Resources & the Environment, Population & Demography, Sciences, Sociology & Psychology, and Transportation. Each of these categories is further divided into more specific subcategories, providing a detailed and organized system for categorizing and organizing documents. The AID Classification Scheme is designed to provide a consistent and organized way of arranging documents on the shelf, allowing users to easily locate related materials. By using the scheme in conjunction with the AID Thesaurus, users can ensure that their documents are accurately indexed and easily accessible.
