Take a look at the titles on your list. Here are some examples:
Robert Korstad and Nelson Lichtenstein, “Opportunities Found and Lost: Labor, Radicals, and the
Early Civil Rights Movement,” Journal of American History 75, 3 (December 1988): 786-811
Adam Fairclough. Better Day Coming: Blacks and Equality, 1890-2000. Reprint edition.
The first one is a journal, and the second one is a book. Here's a detailed explanation about APA citations and how to identify them.
Copy the title of the article “Opportunities Found and Lost: Labor, Radicals, and the Early Civil Rights Movement” (If you copy the title of the journal, "Journal of American History," your search won't work)
Remove the punctuation between the quotation marks but keep the quotation marks themselves. It should look like this: “Opportunities Found and Lost Labor Radicals and the Early Civil Rights Movement”
Paste them into the search box on the library home page.
Hit enter or click Find It.
The article, if it is available online, should be one of the top results in the list.

The second example is a book. Repeat the same process, but remove 1890 - 2000 from the title.
Paste "Better Day Coming Blacks and Equality" into the search box.
Hit enter or click Find It.
If the item is a print book, you can go to the library to find it yourself, or place a hold and pick it up at the front desk. You will need the call number, the status and the location to find the book if you want to search for it in the library.
