Edifix can fully parse and restructure reference entries for journal articles, books, and book chapters. If it encounters an entry of a type it doesn’t recognize as one of these (e.g., a reference to a website), it will move on to the next entry without parsing it; that’s an unparsed entry. If Edifix can tell that the entry belongs to one of its parsable types, but can’t fully parse it (e.g., because it contains too many unrecognizable elements), it will get as far as it can before moving on to the next entry; that’s a semi-parsed reference. 

Edifix can also parse, but not restructure, entries for conference papers. Because these entries are not restructured, they will show up in gray in your results.
