DDC Thousands 000 - 099

Note: Some sections of class 000 are dealt with in more detail elsewhere on this website. See DDC 001 to 025.213

000 Computer science, information & general works: TF8d for computer science; others too vague

001 Knowledge T

002 The book T4

003 Systems This class mixes works on method (mathematical modeling of systems, T4) and theory (TT Cutter Sys), and descriptions of real world systems (which are best classified in terms of the key causal links involved). Again most work on systems is classified within disciplines. With respect to theory types, systems theories can embrace all types of agents, both actions and attitudes (though actions are more common), all types of decision-making (though rational is most common); new equilibria and nomothetic are common characteristics. We will have an entry for systems in class X.

010 Bibliography T4c. Note that very few works should be classed here: works about how to compile bibliographies would be T4c – TM0. Actual bibliographies will be classed with the subject under study. <various> – T4c. Bibliographies of bibliographies on a range of subjects would be classed as T4c – T4c. Another possibility is →gc T4c [creating bibliographies]

011 Bibliographies Bibliographies of bibliographies on a range of subjects would be classed as T4c – T4c. Bibliographies of encyclopaedias would be T4a – T4c. Bibliographies of general knowledge or diverse topics are T – T4c. All other bibliographies will be classed under their subject(s), with the notation – T4c. In particular, bibliographies of works in particular languages will be classed as <language> – T4c.

012 Bibliographies of individuals Iyyy – T4c; for a group SC1f yyy – T4c [Note need not code for ‘works of’ as this would be redundant.]

013 [Unassigned]

014 Of anonymous & pseudonymous works T4 (QB6) – T4c

015 Bibliographies of works from specific places T4 (N1 yyy) – T4c

016 Bibliographies of works on specific subjects will be classed as T4 (<phenomenon(a) or TF yyy>) – T4c.

017 General subject catalogs General works at T8c Catalogues from particular libraries use Cutter numbers for the name of library: T8c (Cutter)

018 Catalogs arranged by author, date, etc. T8c (TM9)

019 Dictionary catalogs T8c (T4b)
