Due to continued problems with last week's misconfigured test deployment, the datestamp for the daily citation updater for OAI-PMH got out of sync again on 14 September.
We've rerun the citation updater from 14 September forward and it is up to date now. OAI-PMH users will need to get the data from start of 14 September through end of 15 September. 16 September's data will be available tomorrow, 17 September, as of about 07:00 UTC.
