One way to quickly find references on your topic is to find bibliographies about your topic. If the bibliography is dated, all you need to do is to search for material after that date.
(i.e. Tunisia Bibliography 1944-2015 then you only need to research Tunisia in the databases for published research beginning in 2016 to present)
This is just a sample of bibliographies available in the library. Ask the reference librarians to show you how to search for bibliographies in our catalog.
