The internet is considered not to be a very reliable source. How much internet sources do you have as opposed to books, articles etc.?
If you have 8 internet sources, but only 5 books/articles/whatever, then I'll be worried.
Having books/articles dominating your resource list shows that you have at least gone through the effort. Try the
State Library if you are desparate for some last minute resources. I have to warn you though, you cannot borrow books from there. You can only
request [this is where you fill out a 'slip' with the title, author, ref number etc. after you have searched for the book] the item, and then after a while
pick them up from the shelf [the kind librarians actually go and find it for you although there are some books that do not need requesting and are on the shelf on the lower floor], read/skim through it, write notes/photocopy [I think, form memory, it costed around 20c, not sure though], and then return it back in a different shelf. They also have lockers just outside the library to put your bag in [bags not allowed in the library] and if you are taking another textbook into the library, you have to fill in this form before, or when, you enter [this is to verify that it's yours and not the library's].
If you already know the process of the State Library, then you have just wasted about one minute reading my [very detailed] explanation
