Section 921. Current minute books and indices in office of county clerk of New York county

1.  The county clerk of New York county must keep books
  to be known as current minute books. Each half page  of  space  in  each
  book,  or  one-third  page  of  space  in each book if it is deemed more
  practicable to subdivide each page in  thirds,  shall  be  consecutively
  numbered for each year and shall be devoted to one action or proceeding.
  On  a  half page or one-third page so numbered the clerk shall enter the
  title of the action or proceeding having the same number for that  year,
  with  the  names of the first plaintiff or party and the first defendant
  or party and the names of the attorneys in full,  and  in  chronological
  order  a  brief  description of each paper as it is filed, together with
  the date of filing thereof, also the verdict,  report  or  decision,  if
  any,  rendered  in  the  action as of the date of the rendering thereof,
  also  all  orders  and  judgments  in  the  action.   All   preliminary,
  interlocutory and provisional proceedings, and proceedings supplementary
  to  judgment  or  execution,  shall  be entered on the same half page or
  one-third page of the minute book as the action out of which they arise,
  or to which they relate, except in actions  where  the  entries  are  so
  voluminous  as to require one or more additional half pages or one-third
  pages of space, in which case the entries shall be continued  under  the
  same  number  upon  other  pages  of  that  or a subsequent minute book,
  reference thereto being  entered  at  the  end  of  the  first  and  all
  additional half pages or one-third pages.
    2.  There  shall  be  kept an alphabetical index of all the actions or
  proceedings entered in such current minute books during any year,  which
  index  shall  consist  of  two  sets  of separate volumes, one set to be
  designated and used  for  indexing  actions  wherein  the  plaintiff  or
  plaintiffs  are  individuals,  including  all  individual  members  of a
  copartnership or of a firm doing business under a firm name or style  as
  stated  in  the  title of the action, and the other set to be designated
  and used for indexing actions wherein the plaintiff  or  plaintiffs  are
  corporations,  a  joint stock company, a copartnership or a firm name or
  style under which a person or persons are doing business.  Each of  such
  sets  of  index  books  shall have a separate volume or volumes for each
  letter of the alphabet,  except  that  the  county  clerk  may,  in  his
  discretion,  include  more  than one letter in a volume when convenience
  will be served, and a suitable marginal page index, and shall  have  the
  designation of its set of books, its letter and the year or years of its
  entries  plainly  marked on its back and cover.  And all such actions or
  proceedings shall be indexed in such index volumes according to all  the
  names  of  the plaintiffs of each title, as contained in the first paper
  filed therein, in the same manner as it  is  provided  in  section  nine
  hundred  twenty-two  of  this  chapter  that  judgment  debtors shall be
  docketed in the judgment docket books,  and  in  every  case  the  index
  number of the action shall be entered opposite the name indexed.
    3. Whenever an action is transferred to another court, or the place of
  trial  changed,  the  clerk  to  whom  the  papers  in  such actions are
  delivered shall bind them and file them together and shall enter in  the
  current  minute  book  in  which he makes entries an entry of the filing
  thereof, and shall continue to make subsequent entries  therein  in  the
  same manner as if the papers had originally been filed with him.
