It been years since I have ordered a dissertation but I ran across one today that isn’t already on the web.
I landed at ProQuest but there was no obvious place to search for a dissertation.
Ah, that’s because you have to follow “Order Now” before this interface is displayed:
I wasn’t “ready” to order so I missed the obvious link for several minutes.
Tip for ProQuest: Search Dissertations link should be on your homepage. (Who approved your homepage design? Management?)
