You need to know a journal’s homepage URL for your APA citation. How do you find it?
Handout on Finding Journal Homepage URLs
You can search in Google, but often that brings up links to libraries that subscribe to the journal. To determine which URL is the journal’s homepage usually requires you to know the publisher or association that publishes it. Somewhat esoteric information!
Another way to find the homepage is to use Ulrich’s Periodicals Directory, a database that lists journals, their publishers, homepages, which other databases index them, and tons of other information.
Type in the journal’s title. Searching by title often brings up 50-100 similarly titled journals.
Type the journal's title into Ulrich's search box.
Find the journal you want, click on the name of the journal, scroll down the page. There’s the homepage for the journal. I’d click on that, just in case it’s outdated. 
Check to make sure the home page is up to date!
If you’re in an EbscoHost database, clicking on the journal title in the record will bring you to a page about the journal. The journal’s homepage URL is listed. Again, check to make sure the link is still accurate.
Click on the journal's homepage to make sure it's still active.
If it leads to just the publisher’s website, it usually has a search box. Type in the name of the journal to find the journal’s homepage. Let me know if you need more info!
