Re: Which facets are most used?

Thanks, Emily.

I do have some additional questions:

1. What was the rationale for moving the LCC facet from the top of the
page to the left with the other facets? And has the usage of that facet
has increased or decreased significantly since that change?

2. Do you have a sense of whether facet usage at NCSU's implementation
is fairly typical of Endeca implementations at other academic libraries
(e.g., TRLN, McMaster)? The reason I ask is that I notice that the
overall numbers on search vs. navigate vs. search, then facet at FCLA
[3] seem to be significantly different than the equivalent numbers in
the NCSU PowerPoint.
