Whether on-campus or off-campus, you can directly access OHO here: http://www.oxfordhandbooks.com.ezproxy.sbts.edu/
If you are off-campus, you will be asked to login with your normal SBTS login credentials.
A link to OHO can also be found on the library Databases & E-Resources page.
You will see OHO listed in the New Databases section on the right side of the screen and in its permanent home in the O-section among several other Oxford online resources.
If you are off-campus, after clicking the link, you will be asked to login with your normal SBTS login credentials.
