How do I access magazines using Libby / Overdrive?
Answer
Once you have downloaded and signed in to the Libby app (see instructions here), click on the library icon at the bottom of the screen:
On this page, click on the three horizontal lines located beneath the library's logo on the top of page: 
This will bring up Libby's content filters. On this screen, beneath the heading "Format", select "magazines". Then choose the subject you wish to browse or choose the option "SHOW # TITLES".
When you find a title you would like to read, click "Borrow" to add to your shelf.
You can search for specific magazines by clicking on the search icon (magnifying glass) at the bottom left corner of the screen and entering the magazine title into the search bar.
