One journal I am working with is not outputting titles in the OAI-PMH feed. You can see examples of this here: http://journals.fcla.edu/ijp/oai?verb=ListRecords&metadataPrefix=marcxml&set=ijp:ART , where there are blank 245 fields in the MARCXML feed. When I look at the individual articles, I see title metadata is stored in OJS.
OAI-PMH feeds for other journals on the same install do not have this problem and output title info correctly and completely.
Does anyone have any pointers on what might cause 245 not to output on this particular journal?
