Hi, I am sorry you are having trouble!
The easiest way is when you go to www.allencc.edu then to the Library Tab, you will see a tab called Database Access. That is where all the databases are that the Allen Library subscribes to. Films on Demand is the 8th one down.
Another way things can be found in our library system is to go to Library page and click on Library Guides Home Page or Library Resources. This page has search boxes and search tabs in which you can search all the help guides we have for your research. If you type in 'Films On Demand' it will give you a list of all the guides that have that information on them.
I hope this helps you in your search!
