Ask HN: Where do you get your scientific papers from?

I'm currently both an IEEE and ACM member; I find the IEEE digital library to be somewhat of a joke - ACM is much better in comparison, but still lacking.

I don't like putting 100 bucks in a million different organizations in order to be able to search for science (which should be open to all!) so this begs the question: what's the most cost-efficient method of obtaining scientific papers for research? Also, what resource has the best search engine for said papers (both ACM's and IEEE's engines suck)?

Thanks!

I'm very much dependent on university journal subscriptions to get full text articles - mostly from sciencedirect. It's a shame, as it puts so much stuff out of reach if you're not in the same position.

I think in the CS and math fields arxiv can be very useful, but papers in my field (mostly CFD related) are fairly sparse.

It might be worth seeing if you can still get access from your university, even if you no longer attend or are affiliated/employed. I know mine offers library services to students after graduation (for life I think), which I assume includes access to journals.
