get_date_from_doi function

Function to retrieve publication date based on Digital Object Identifier (DOI)

This function retrieves precise publication date by querying the Digital Object Identifier (DOI) web server. Alternatively, if extract_date_from_doi is set to TRUE, the function will first try to extract a publication year from the publication DOI string. If create_bibliography is called with retrieve_pubdates = TRUE, it calls get_date_from_doi for each record to confirm publication dates.

get_date_from_doi(doi, extract_date_from_doi)

Arguments

• doi: Character string representing the Digital Object Identifier (DOI) of the publication
• extract_date_from_doi: Flag indicating whether to try to simply extract publication year from the DOI string before restorting to online queries to the DOI server

Returns

Returns a date in YYYY-MM-DD format or YYYY-MM format if extract_date_from_doi is set to TRUE.
