I've always been curious, why do journal articles seem to be so proprietary? There's like 20 different search engines out there, all that only carry certain journals, and pretty much all require subscriptions to be able to view anything. And if you don't have a subscription, they're way too expensive, on the order of $40 to view an article that may or may not have anything useful to you in it (I honestly don't know of anyone in their right mind who would purchase the articles individually lol). Do people really make that much off of publishing the journal articles themselves?
It just always seemed to me like that sort of information would be far more beneficial for everyone if it was publicly available, maybe even all compiled into a single, comprehensive database so that you wouldn't have to search through all of these different sites! But then again, I don't know much about the actual economic side of publishing, so I'm not sure how viable it would be from a business standpoint. I got curious recently because at my university, we have access to about 10 pretty good search engines for journals. But we're still missing a couple of the other major ones, and because of that I end up missing out on some very good articles out there that have a lot of great information in them. Not to mention, I found that when I was in the workplace I often needed to reference certain research papers for design considerations, only to find that we didn't have access and the company wasn't willing to purchase them.
