There are several research tips that take history majors to the next level.
Notice other subject terms on book record pages you can use as keywords or searches yourself:
Get in the habit of checking the publisher--university press publishers should be fine to trust as scholarly monographs, as should some standard trade academic publishers (Lexington, Rowman & Littlefield, Routledge, etc). Look for footnotes and endnotes and avoid popular press publishers and popular as opposed to scholarly historians.
You can search in and borrow from other libraries for free--watch the video linked below to start expanding your options.
Documentaries are gold mines for ideas, if not more resources for your own evidence. You will find them in both the DVD shelving and in our streaming film databases.
