Multiple references with same author and date
When multiple references have an identical author (or no authors) and publication year (or no publication year), include a lowercase letter after the year. This lowercase letter is also included in the reference entry.
Use only the year with a letter in the in-text citation, even if the reference list entry contains a more specific date.
