Title: What we (do not) know about sublinear separators

Starting from the famous planar separator theorem of Lipton and
Tarjan, the notion of sublinear separators played an important role 
in the algorithmic graph theory.  However, it began to be explored 
from the structural point of view only recently.  I will survey 
the known results on the properties of classes of graphs with 
sublinear separators and present a number of open questions.
