Combining worksheets

[walshpark]

I have a mailing list on 3 separate PCs, which are not networked. Can I
update the lists separately, then combine them onto a Master? Of
course, I don't want to lose data, and need to keep from having
duplicate and triplicate entries.

Is this possible?

Thank you very much to anyone who can assist me!
