I do not understand how to find the Name of Site etc. for citing these sources in MLA Format. Please help.?

I have the following two websites:





http://www.courseptr.com/ptr_detail.cfm?group=Game%20Development%26amp;subcat=Physics%20%26%20Math%26amp;isbn=1%2D59200%2D093%2D2





and





http://search.barnesandnoble.com/Physics-Modeling-for-Game-Programmers/David-Conger/e/9781592000937





How am I supposed to get the name of the website, the date it was published etc.? It doesn't say it anywhere or anything. I NEED THESE SOURCES, and I need to know how to cite them. Please help! Thank you so much!|||you can find inf in the bottom of the page under copy right... just click on it|||In these cases, I would say that the names of the websites are Course Technology PTR and Barnes %26amp; Noble, but since there's no date anywhere, I'd leave it out. That's just me, though.
