Lattice theory is the study of an intriguing class of partially ordered sets known as lattices. Within this subject, there are many hard open problems. One such problem is to determine which countable lattices are sublattices of free lattices. In this talk, we will describe past progress on this problem and propose possible methods of attack using finite and finite width lattices. This research was done while I was a masters student at the University of Calgary.
