Hi all, I am sending SRU queries to the WorldCat in the following form: String host = "http://worldcat.org/webservices/catalog/search/"; String query = "sru?query=srw.kw=\"" + keyword + "\"" + " AND srw.ln exact \"eng\"" + " AND srw.mt all \"bks\"" + " AND srw.nt=\"" + keyword + "\"" + "&servicelevel=full" + "&maximumRecords=100" + "&sortKeys=relevance,,0" + "&wskey=[wskey]"; And it is working fine, however I'd like to limit the results to those records that have a DDC number assigned to them, but I don't know what's the right way to specify this limit in the query. NOT srw.dd="" NOT srw.dd=null Neither of above work Thanks, Arash -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Chad Benjamin Nelson Sent: 15 May 2012 21:54 To: [log in to unmask] Subject: [CODE4LIB] Atlanta Digital Libraries meetup - May 23rd The first / next Atlanta Digital Libraries meetup is coming up soon: Wednesday, May 23rd 7pm Manuel's Tavern<http://www.manuelstavern.com/location.php> 602 N Highland Avenue Northeast Atlanta, GA 30307 North Avenue Room We have two scheduled talks, and are still looking others interested in presenting.
