Lotdiss is a LaTeX class for dissertations at the Landelijke Onderzoekschool Taalwetenschap (LOT). You'll need the main file, the option file appropriate for your institution, and the document template. It wouldn't hurt to look at the documentation too.
The current version is 1.3b (August 13, 2013). The most recent changes involve updates to the LOT and Utrecht details. Everyone should update.
