The following code will print the GUID and the Major and Minor version numbers for all your references into the Immediate Window.
See AddReferences to see how the GUID and the Major and Minor version numbers are used.

Dim i As Integer
Dim strResults As String
Set VBAEditor = Application.VBE
Set VBProj = VBAEditor.ActiveVBProject
For i = 1 To VBProj.References.Count

Name & vbTab
strResults = strResults & VBProj. _
References(i).GUID & vbTab
strResults = strResults & VBProj. _
References(i).Major & vbTab
strResults = strResults & VBProj. _
