However, I sometimes see the ArXiv expenses and cost per manuscript reported incorrectly with just the direct costs rather than the total expenses including the indirect costs being reported. According to the ArXiv Business Model - https://confluence.cornell.edu/download/attachments/127116484/arXiv+Business+Model.pdf - total expenses for 2013 are estimated at $837,760. I couldn't find an estimate for 2013 uploads but in 2011 there were 76,578 uploads with total expenses of $586,833 - about $7 per upload. ArXiv expenses are expected to increase 43% from 2011 to 2013 and so the cost per upload may be going up. If all the features are added for "ArXiv-plus" who's to say the costs wouldn't be much higher? Regards, Ed Pentz
