Re: arXiv? Really?
I have downvoted, but not out of malice I can assure you. arXiv is indeed full of some utter dross, but as it's a pre-publication site there are a lot of papers in there that will have been published. For someone like me who has no access to the relevant journals (or just plain too stingy to pay for them) it's an invaluable source. Okay they might be a bit rough around the edges before actual publication, but still.
I wonder if there's anything in their data set that flags whether the arXiv paper has actually gone on to be published in a reputable journal. Now that would be very useful.
