sharepoint doesnt take care of duplications out of the box, you can easily do it by object model where you can cancel all the new / Editted items that contains a title used in on of the old items.

Write an list item event handler (http://www.wrox.com/WileyCDA/Section/Programming-Event-Handling-in-Windows-SharePoint-Services.id-306329.html) that overrides the ItemAdding method. In this method you want to check if the title exists (i.e use a CAML query not a foreach loop, its more efficient) if it does not exist then add it, other wise cancel the action and display a message to the user.

There is a tool on http://www.codeplex.com/features/Release/ProjectReleases.aspx?ReleaseId=2502 called "Uniuq Column policy Feature", download it (*.wsp file) then install it on your server using the following command:

C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\BIN>stsadm -o addsolution -filename "C:\Documents and Settings\Administrator\Desktop\UniqueColumnPolicy.wsp"

then go to Central Administration>Operations> Solution management, you will find a solution called uniquecolumnpolicy.wsp, go and deploy it.

Then go to your document library or list> Settings> docuemnt library settings>Information management policy settings > Select Define a Policy, you will find "Unique Column Policy" then check the "Unique Column Policy" box next to it, then you will have the list of columns in your document library, select the column you want to apply a unique constrains on.
