  -(The catalogue is in progress; various changes and corrections are still to be made.)
  +This is the catalogue of the Library of the Arts and Letters Club of Toronto.  The library itself is on the second floor of the Club, and all members are warmly invited to use it for work or leisure.
  +

  +
  +The collection policy sets out that we collect books by and about Club members or the Club, with added special attention to Toronto and affiliate clubs.  The collection is non-circulating.  Any books taken off the shelf should be left on the table for shelving.
  +

  +
  +There are five sections in this catalogue..  First is the author listing, which is organized by last name.  If there is more than one name, the book only appears under the first, but in future all names may be indexed.  Though it is called the author listing, editors, illustrators and any other notable contributors are also listed.
  +

  +
  +The other four sections are classified listings, where the books are in call number order.  The library uses the Dewey Decimal Classification for nonfiction, and the nonfiction listings are under those numbers (for example, see 759.11 for Canadian painting).  Fiction, poetry and drama are subdivided by author last name.  On the shelf, their call numbers are under FIC, POE and DRAM (so Rosemary Aubert's poetry is under POE AUBERT and John Coulter's plays under DRAM COULTER).

  +The catalogue is also available as a PDF on the Club's web site.

  +
  +Most of the books in the Library have been donated, by their authors or others.  The Club is very grateful and thanks everyone who has ever donated something to our collection.
