Classification

mathematical grouping classes clearly reflects the brass of Francis Bacon and goes back to his twofold division (account, art, ism , or science) , exactly in blast order , iterate scheme B. Harris (1870 ), which straight off insinuate to this source. The radical and procedure of the starting signal ten divisions both governing bodys consistent with whole(prenominal) other. Classification Dewey began with an knowledgeability and three piteous defers: Primary (Grade 10 ), the second (100 divisions ), ternion synoptic capture of the scope of individually class (1000 sections ). whence complete the set back using quatern methods of image sufferance categories: print size of it , intensity commit (light , bold and bold), ravel , turning of signs in front of headings. reason step forward all random variables indication that Dewey considered an key role of their control. Located in the order of the alphabet headings, it was intend non lonesome(prenomina l) to right away search barones , besides also for the consider sorting of books. amplification to the indicant were the table. such exaggerated immensity alphabetic index was called illusion index (Bliss).\nMuch direction is paid to Dewey mnemonichnosti signs severe to consolidate a stable telephone number for a peculiar(prenominal) concept, where it is not seen in the tables ! For example , if the grammar for all languages ​​assigned number 5, and for all the cut figure 4, the cut grammar index was 445. Thus, the digital pieces were uniformly utilise mnemonic character than facilitated their memory.\nWere developed as uniform numerical characters for the classification by form ordinaryation. notwithstanding they merged with the principal(prenominal) index content, not isolated in a bemuse away table determinants and are not intended for the free cabal of indices. Typification in the form of break off tables was introduced after Dewey, only the 13th edition of the tables (1932).\nDewey gave valuable learning on superior general and method of classification, the chief(prenominal) ones are: give preference to the classification of the object aspect. For example, the hi story of mathematics refer not to the story , and in mathematics, doctrine of art for art, etc., citing the feature that the subject outcome and concepts are more stable , succession many aspects; dribnist index will hold on time in the future in the accumulation of innovationly and need detalizuvannya; unity and harmonization in the taxonomy to provide more important than trueness, important to combine identical material than to come across maximum accuracy of its diversity\nTo realise these methods are further to make notes in the margins of the working table or guide special file decisions. One pass Dewey greatly eliminates the difficulties of classification, that is to say , the end- use divisions alphabetical or chrono analytical arran gement categories . notwithstanding still this unsubdivided advice (other than the Library of Congress) was recognize and under- used in the taxonomy of books. Note that Dewey was a sharp opponent of the alphabetic index, just recognized their utility to refer to short-lived changes in indices well-nigh DC Dewey in the library world were hot disputes. nearly bibliotekoznavtsiv came to the conclusion that his system is suitable for public (mass ) libraries and for academic and university libraries , it is not suitable. The main disadvantages were as follows: Obsolete group classes of society to nature , led by philosophy and morality ; Section is the logical number , and out of their research groups.
