Where can I find Schinkel's submitted architectural designs for the Friedric

Question:

Where can I find Schinkel's submitted architectural designs for the Friedrichswerder Church?

Karl Friedrich Schinkel (1781-1841), Friedrichswerder Church (in Berlin).

I don't need detailed architectural plans; I just need a general picture of the four or five designs that he proposed. I can't find it through Google or Wikipedia. Thanks a lot.

Best Answer - Chosen by Asker: I don't see the designs themselves online, but maybe your library has this book:
Sammlung architektonischer Entwürfe. Auswahl- Reprint aus der Ausgabe 1841-43
by Karl Friedrich Schinkel
ISBN-10: 3760585485
ISBN-13: 978-3760585482

Or try an interlibrary loan.

It's available used via Amazon.de (not .com) and Abebooks.com, but all the sellers are asking high prices (starting at 40 EUR, not including shipping). Try FLickr.com and go through the gugenheim archive.
