Where to put declaration in phd thesis? I am doing my PhD in an europe university and they have almost no requirements about the thesis formatting. I choosed the following outline:


Titlepage
Acknowledgment
Content
Chapter 1 - Chapter 3
Summary
Bibliography
Declaration


Now I wonder, is there a commen position for the declaration page (such as the first page after the title page or so?).

My declaration pages states that I did the work by myself and have not handed in the dissertation elsewhere.

I am a bit surprised, because in all so far viewed phd thesis I didn't find a declaration at all. Is this often taken out befor the thesis is published online?
Not every university demands such a declaration (e.g., stating that it is your own work, and all external sources have been properly cited, referenced, and acknowledged). I had one in my master thesis, but not in my PhD thesis (performed at a different university). Just follow the university rules. If they demand a declaration, then typically there is a verbatim text that you have to put in.

If your university does not prescribe where it should come, but does demand that you have a declaration, then you are free to put it anywhere. It is, however, wise to follow the convention of your university, and put it where others have put it. As @scaaahu indicated, you can go to the library and look what others did.

(Btw, I have seen it typically somewhere at the beginning.)
