@holger: Yes, I do indeed remember that, now that you mention it, thank you. I'll have to read it again more carefully, but as I recall, no one else had any really good alternative either.
@Hein: Well, okay, it may be paranoid. I just don't see any other reason for the exact same link to show up a second or third time. It only happens when you go through a couple of pages of links and don't actually click on any of them, just scan to see which ones might be useful.
Thanks BTW for your correction about 'filtrate.' I shouldn't have guessed, there's been way too much water under the bridge since high school chemistry. At least I knew it was a noun. (-;
@Norbert: Okay, maybe I'm misunderstanding something about the URLs, it could well be, I wouldn't be surprised, since I'm really a fuzzy, not a techie. (If those terms aren't already hopelessly out of date.) I just think I've noticed that if you only want to copy a URL, not actually open the link, you can right-click on it, but instead of its own name under Properties you get its name prefaced by google.com plus some code and followed by a little more code for the Google search button. This extra code was not always the case, then it was for several months or a year, then it wasn't for a few months, and now it has been again the last couple of weeks.
But then right this minute, when I checked, it wasn't. Very interesting. I'm absolutely certain I'm not imagining this, in fact, I could swear that earlier this very day I've copied a couple of links and had to edit the Google garbage out. Or at least yesterday or the day before.
I do use scholar.google once in a great while, but it's sort of a nuisance to get to since there's no link directly to it from the main search page. For the few things I've tried it for, it seems to have a much higher percentage of medical and scientific/technical articles than ones in the humanities.
And if you actually try to click through to the full text, often you find that it's only accessible from a university-affiliated computer subscribed to some special service. I wish I was a university or had a password to a university system. I checked that out at my own dear alma mater and of course there's nothing like that available for alumni, not even access to the university library system. So much for all that tuition. And they wonder why I never respond to their constant fund-raising efforts ... <sigh>
Sorry, maybe I'm just in the mood to gripe about things. At least the weather hasn't been that bad lately, a little rain. Or at least thunder.
