What's in a name? The case for Weinberg, Wajnberg, or Vainberg?

The story of Weinberg's music since his death in 1996 has often started with one key issue: how to spell his name. This might seem obvious, but in Weinberg's case, it is wrought with problems. There are several options, each with their own line of reasoning:

         Weinberg
         Wajnberg
         Vainberg
         Vajnberg
         Wainberg

This might not seem like much of an issue, but when it comes to things like searching archives or record labelling, the significance becomes apparent. As you might have noticed, I stick to the 'Weinberg' spelling, but even I am beginning to have my doubts about this option.

Of course, David Fanning's monograph on the composer uses the 'Weinberg' spelling, as does the Osteuropa 2010 issue, and the majority of western CD releases. 

In this article, I'll quote several authors on their reasoning behind their choice of spelling, before providing some further examples. The final choice, I believe, rests with the reader.
