Clasificaciones y Definiciones: notas para un bibliotecario

EACH CLASSIFICATION IS HISTORICAL, RELATIVE AND SUBJECT TO THE PRACTICE OF THE PERSON USING IT. THE VARIATIONS ARE NOT SOLELY DUE TO THE PRACTICAL INTERESTS OF THE PERSON WHO IS CLASSIFYING OR DEFINING. REAL VARIATIONS OF THE GROUPINGS AND SUBGROUPINGS, OF THE MOVING UNIVERSES AND ITS PARTS, ARE ALSO PRESENT; AS WELL AS, IDEOLOGICAL ELEMENTS THAT HIDE, FORBID, THAT FORCE A CLASSIFICATION IN A CERTAIN WAY; ELEMENTS THAT INFLUENCE THE COLLECTION DEVELOPMENT. THE HISTORY OF CLASSIFICATIONS SHOWS THAT THEY ARE USED TO ORDER, ESTABLISH DIFERENCES, HIERARCHIES, GENDERS. CURRENTLY, THE INTERDISCIPLINE HAS DEEP IMPLICATIONS AND DEMANDS A NEW KNOWLEDGE ORGANIZATION WITHIN LIBRARIES, WHERE BOOKS MAY BE THE OBJECT OF MULTIPLE CLASSIFICATIONS, FOLLOWING RATIONAL OR FUNCTIONAL ORDERS, USEFUL TO INTEGRATE NEW BRANCHES OF KNOWLEDGE. THESE CLASSIFICATIONS SHOULD CONSIDER LIMITS, RUPTURES OR DISCONTINUITIES, BESIDES TAKING INTO CONSIDERATION THAT A BOOK CAN BE CLASSIFIED WITHIN TWO OR MORE SUBJECTS. FACTORS SUCH AS QUICK AND OPPORTUNE LOCATION SHOULD ALSO BE CONSIDERED IN BOOK CLASSIFICATION, FOR THE PURPOSE OF RELATING BOOKS TO DIFFERENT FIELDS OF KNOWLEDGE.
