Correspondence : The widespread use of the telephone seems to have reduced the volume of correspondence that is generated in developed countries. But countries like our India, there will still be correspondence. If the volume of this is small, a lever arch file is suitable: file incoming letters in the front, and copies of outgoing letters in the back. Incoming letters can be numbered whilst outgoing letters can be filed by alphabetical order of the addressee and put in date order. It might be useful to keep a brief summary of each letter at the front of the file; an example is shown in Figure.

These letters are also kept in date wise order and with the most recant one having the highest number.
