… description and function 
 
 

   Each catalogue record is governed by general rules. If the place of publication is unavailable or not possibly to identify, the letters B.m. - "bez mista" (i.e. place missing) are used, if this should be the publisher, the letters b.n. - "bez nakladatele" (publisher missing) are used, or the letters may be combined, e.g. B.m.n. - "bez mista a nakladatele" (place and publisher missing) or B.m.n.d. - "bez mista, nakladatele a data" (place, publisher and date missing), where no publishing data is available.  
  
   In the catalogue record appear unabridged titles and subtitles, or, where applicable, concurrent titles and all originators, including editors, artists, and authors of contributions to anthologies and collections. They have beenleft out only in the rare case where their large number would unduly encumber the entry; these are, generally, authors of contributions quoted from other publications. We have also tried to identify all pseudonyms, abbreviations and ciphers, as well as to find out publishers and places of publications where these had not appeared; we have also added the date of publication whenever possible. Such secondary data appear in brackets, as well as formal descriptors, included only in cases where general character of the publication is not apparent from the title or subtitle. The record entry is ended by a class (shelf) mark, under which the publication is field, and an acquisition number, under which it is recorded.  

   The catalogue is provided with four indexes. The author index contains the principal, as well as secondary authors, including their roles, in coded form. The code list is enclosed. The personal index contains names of persons written about or mentioned in the publication. However, the index contains only the names substantially dealt with in the publications, or names of  authors whose relevant biographical note appears in the book. Publisher index contains names of publishers and editors, generally in the form that appears in the publication. The title index contain titles, subtitles, and concurrent titles of works; longer titles and subtitles have been reasonably shortened. Should a title start by a character other than a letter or a numeral, the character has been omitted. Should the first character be a Roman numeral, it may be found under the appropriate letter (I, V, X).
