I'm not sure if we're talking about the same thing here?

Say you need to research some scientific algorithm or other, you paid $40 per paper just to do that? There will be 3-5 papers that are must-read, so $120-$200. Then there's another 5-10 papers that are referenced in the former, you might want to check, just for the few paragraphs that are referenced, which may contain crucial elements of the algorithm you are trying to write (often not explained in full in the original papers).

Even if you have that money to spare, wouldn't your research be hampered by the choice you stand whether that one extra paper at $40 is going to be worth the money?
