Document keeps getting duplicated every time I save

Question

I think my preferences have been set up so that every time I make changes to my document I seem to be getting a new copy every time, so that instead of just working on one version, I suddenly have about three or four documents with the same document name. I had this problem once before in Quark and I was told to do something in the saving function in prefernces, but I don't know where to find this in indesign. Please help. Thank you lots.

I don't think this is what's going on. Doing a Save As each time would would bring up a dialog asking for a name and location, so it would be hard not to notice that you are either making a copy by using a new name or location, or you would overwrite the old file by using the same name and location.
I suspect what's really happening is the OP has been issuing the Save a Copy command, which by default is Ctrl (Cmd) + Alt (Opt) + S. Ironically, your suggestion to use just Ctrl + S should also solve that, since that is the correct command if the shortcusts are set to defaults, but it bears noting that it is possible to edit the keyboard shorcuts so that, for example, the Save and Save a Copy commands are reversed in their use of the second modifier key.
This sort of confusion would only occur when using shortcuts, and not from the file menu. I can conceive of the possibility, too, that a Mac user might be able to accidentally hit Cmd + Opt together with the same finger since the keys are adjacent.
