There seems to have been an unfortunate accident whereby every entry in our bibliography is now duplicated, such that we are showing 16,000+ items, when there are only actually 8,000. Once a bibliography reaches this size, it is almost impossible to delete the whole thing and re-import it. I don't know what to do at this moment, except to ask people who use the resource to delete as many of these duplicates as possible!
OK, I was able to determine that whoever added these, did it as one batch. I was able to determine the date they were added, and deleted all entries from that date. I hope this was an honest accident, and not mischief!
