It depends if you want to file by the literal name or the industry. What are the filing rules? E.g., is the company name Joanne Abbey?

[Sharoninf1]

File by literal name. Yes, Joanne Abbey is the company name.

[Wondergirl]

File by literal name. Yes, Joanne Abbey is the company name.

Then that has to be under "J" as does "J.B. Schmidt Co."

Thanks! And what about the others company names in the first post?

Thanks! And what about the other company names in the first original post?

Are you there?

If you are alphabetizing by company name, you keep the name intact --

Buster Brown Shoes (not Shoes, Buster Brown)
L.L. Bean (not Bean, L.L.)
Montgomery Wards (not Wards, Montgomery)
Sears, Roebuck & Co.
Warner Books (not Books, Warner)

Now, put your list in ABC order by company name.

Either you take advice of the experts, or you get off the board.

What book are you referring to ? It isn't a proper book for filing alphabetically.

Filing rules are universal, or no one, absolutely no one could understand a system. Your reference means nothing unless you can file a link to what you are referring to.
