Hi,
the school I did my PhD at did not publish my dissertation for some unknown reason – they are usually pretty good at self-archiving these things. This might have been out of copyright reasons(?). However, I found out that all publishers allow me to self-archive the articles. Thus, I have no problem putting the whole dissertation online (yay!):
Optic Flow in Behavior and Brain Function of the Zebra Finch
Have fun
