What is the best way to sort letters, correspondance?

Question

How do you sort your letters into files or folders, I meen paper not on the PC

Could you give me suggestions on what headings to use, I am thinking of using files with plastic sheets.

Answer 1

I sort them by sender if they are personal and I get a lot of letters from them. If it's a rarity to get a personal letter, I toss them into one folder marked personal letters. If it is a business letter or a letter about my geneaology research I include it in a folder marked with the topic: Taxes, Business, (Family Name), Complaints, Etc. Hope this helps.
