A Classification of the Bird Species of South America

"The South American Classification Committee is an official committee of the American Ornithologists' Union whose mission is to create a standard classification, with English names, for the bird species of South America. This classification is subject to constant revision by the proposal system to allow incorporation of new data. The SACC hopes to have this classification published as a printed document within a year or so.

National Land Cover Data Classification Schemes

"NLCD 1992 was a success, and its success had a lot to do with building the momentum for NLCD 2001. NLCD 2001 improves upon NLCD 1992 in three important ways. Whereas NLCD 1992 was simply a land-cover data set, NLCD 2001 is a land-cover database comprised of three elements: land cover, impervious surface and canopy density. Second, NLCD 2001 used improved classification algorithms, which have resulted in data with more precise rendering of spatial boundaries between the 16 classes (an additional nine classes are available in coastal areas and another four classes in Alaska only).

EEO-1 Job Classification Guide

"This guide serves as a crosswalk between the 2000 Census job codes and the ten (10) job categories on the Employer Information Report EEO-1, and is designed to assist employers in correctly classifying employees according to the ten (10) job categories on the EEO-1 report. Each job category is explained in the EEO-1 Instruction Booklet with a definition and examples of the types of jobs included in the category."

North American Industry Classification System

"The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. NAICS was developed under the auspices of the Office of Management and Budget (OMB), and adopted in 1997 to replace the Standard Industrial Classification (SIC) system. It was developed jointly by the U.S.

Association for Computing Machinery Computing Classification System

"ACM's first classification system for the computing field was published in 1964. Then, in 1982, the ACM published an entirely new system. New versions based on the 1982 system followed, in 1983, 1987, 1991, and 1998. The 2012 scheme utilizes a new poly-hierarchical structure and a more in-depth approach than the 1998 version. It no longer uses the letter-and-number coding of the previous versions. The old scheme has been mapped to the new, and both the 1998 and 2012 terms are available on Citation Pages of all indexed articles in the ACM Digital Library.

Mathematics Subject Classification

"The current 2010 Mathematics Subject Classification (MSC2010) is a revision of the MSC2000 that has been used by MR and Zbl since 2000. MSC2010 is the result of a collaborative effort by the editors of MR and Zbl to update their shared classification. These editors acknowledge the many helpful suggestions from the mathematical community during the revision process over more than two years."

Physics and Astronomy Classification Scheme

"The Physics and Astronomy Classification Scheme® (PACS) was developed by the American Institute of Physics (AIP) and has been used in Physical Review since 1975 to identify fields and sub-fields of physics. It is used in a variety of ways, for example, in the online journals as a tool in searching for articles by subject. PACS is arranged hierarchically, by subdivision of the whole spectrum of subject matter in physics- and astronomy-related sciences into segments and then repeating the process of subdivision down to four levels. The latest edition of PACS is the 2010 edition."

Integrative Levels Classification

"The Integrative Levels Classification (ILC) is a knowledge organization system featuring experimental innovations. Although drawing from the heritage of bibliographic classifications, it is different from most of them in allowing to represent any combination of concepts without the ties of traditional disciplines. Phenomena of the world are listed in the ILC schedule according to the natural sequence of integrative levels; each concept can then be freely combined with others by meaningful relationships (facets).
