The Leisure Reading Collection on the 2nd floor is full of recent fiction (and non-fiction) bestsellers. It is a "browsing" collection so you can easily search by scanning the shelves and looking for titles. For more on this collection, please go to http://guides.library.unlv.edu/leisure
The P section on the 4th and 5th floor is all about literature and languages. The PS section (5th floor) is American literature. It's a little hard to browse because it is arranged by time period and then author, plus all the criticism is mixed in with the actual novels, plays, and poetry.
So, we suggest searching in the catalog by author or title at http://webpac.library.unlv.edu/
