The ABBA books I still don't have

Although I currently own 22 books about the super pop group ABBA (well, one of them is actually the book about Agnetha), there are still a number of interesting books I haven't yet bought. These are the ABBA books I seriously consider buying:

Fotografien / Photographs 1974 - 1980
Wolfgang "Bubi" Heilemann (2004)

ABBA: unplugged
Karl French (2004)

A Tribute To Frida
Philippe Elan & Jean-Marie Potiez (2006)

The Little Book of ABBA (aka ABBA & MAMMA MIA)
Claire Welch (2008)

ABBA in America - A pictorial travelogue
Leif Schulman & Charles Hammarsten (to be published in 2010, very soon in fact)

ABBA Guide to Stockholm
Sara Russell (to be published on the 1st of April 2010)

Ah. I love to have pop books on my bookshelf. The problem is, my following purchase will have to be a new bookshelf. There's not enough room for all these gems anymore!
