I'm a non-academic taxpayer trying to read articles and don't have access through my employer or public library. I know other people in the same situation. Emailing the authors directly to request a copy is a known legitimate workaround, but in cases where I'm trying to read a paper on fungal propagation from 1971 (most recent example, from last week) the options are limited.

I would also imagine that if these things were more readily available people would be more likely to use them.
