I’m an academic librarian in the US, working at a state university. In our case, visitors can use the library. During visitor hours, they have browsable access to our print journals, both the current and the older ones in the stacks.
Online journals are a different matter. MOST of our online databases are available through our visitor terminals - these are available to visitors for 1 hour per day. When we cannot make a database available to a visitor, it’s because of licensing restrictions, not because we don’t want to. Beyond us, we’re lucky to have the GALILEO system that serves the state - this helps make some (though not to the levels that universities have) of the scholarly literature available statewide.
This aside, I would point out that your average non-scientist person looking for something in the scientific literature is not going to begin at most of the specific resources, like PubMed Central, listed here - and I’d say that’s understandable, since a good portion of them are not easy to search. They’re designed for people who know the language. And, to be fair, the scientific literature is not easy to read, generally. So, my assumption as to how most people in the general public find scientific literature:
[ul]
[li]Read an article in the secondary literature (Time, Newsweek, Scientific American, the NY Times, etc)[/li][li]Think “hey, I’d like to know more about the effects of wooden tables on people’s eating habits”[/li][li]Go to Google, search for wooden tables and eating habits[/li][li]Read some of the results that come up, which will typically be more secondary literature, companies trying to sell you wooden tables or the like[/li][/ul]
Some will want to go further and will seek out the original research article(s). Hopefully the initial article will give a citation or enough information that they can find that. Typically, they don’t - and most people (at least Americans) aren’t going to take that next step, for whatever reasons. If they do, they can try the sources above or they can get a copy of the article through interlibrary loan at their local public library.
The bottom line is that it’s not easy - though it shouldn’t be as difficult as it can be - and part of that, IMO, is that the systems in place don’t make it easy. We (we being the US) don’t do a good job of teaching the structure of the scientific literature to students as they go through school, so I’d suggest that many people don’t look for more literature - even when they’re interested - because they don’t know how to even begin looking beyond that Time article or the blip on the evening news.
Apologies for the threadjack - you’ve kind of hit one of my nerves with this, and I know we should do better. I don’t know how to fix the system though.
