We don't have access to it either online or in physical form. If you are looking for specific articles, you can make interlibrary loan requests for them.
If you are still a UNO student, ILL information can be found at the links in the middle of the library home page: http://library.unomaha.edu/
If you are not, you can gain ILL privileges by becoming a Library Friend. Information about that is here: http://library.unomaha.edu/information/library_friends.php
