PBS --- Exports references in the tab-delimited format used by ProCite¨. With the exception of the Author and Editor fields, carriage returns within a reference are not removed during the export. Since ProCite interprets a return as the end of a reference, this can interfere with the import process. It is possible to make a COPY of your library and use the Change Text command to remove unwanted returns in the EndNote fields before exporting the references in the ProCite format. RIS --- Exports references in the RIS format so that they can then be imported into Reference Manager¨. REFER ----- Exports references in the tagged format used by the UNIX programs Refer and BibIX.
