Andrew, I'm submitting a second file to you mamf@vebag:~/opt/isni$ ls -lt total 302296 -rw-r--r-- 1 mamf mamf 2840243 May 6 13:38 AuthorClaim_isni.txt -rw-r--r-- 1 mamf mamf 306703943 May 6 03:47 RePEc_isni.txt This has data from the RePEc Author Service (RAS). I created this is 1999 to provide author claiming for RePEc. Christian Zimmermann has been running it from many years, most recently from the Federal Reserve Bank in St. Louis. There are some, very few registrants in both AuthorClaim and RAS. My intention is to automatically detect this and then send you a combined file that would contain the AuthorClaim recorrd only for those double folks. This is on my to-do list. Kindly check the RePEc data. I would rather submit XML data but it is tough to figure out it's structure from the Schema that Janifer submitted to me, and some data elements' semantics is unclear to me. -- Cheers, Thomas Krichel http://openlib.org/home/krichel http://authorprofile.org/pkr1 skype: thomaskrichel
