To find books, start with the Duke University Libraries Catalog. You can change the default (see below) to search the collections of the Triangle Research Libraries Network (TRLN) as well, which includes the libraries of North Carolina Central University, North Carolina State University, and University of North Carolina at Chapel Hill.
Searching for titles by and about Martial is complicated because there is no browse function in the current library catalog, and there is no indexing by his Latin name. The best approach is to start with the search string below. You'll be able to narrow the search results with the facets on the left hand side of the screen. I'll demonstrate this in the first workshop.
