#      df[2,1:3] <- c("cuccurullo","corrado", "naples")

## run idByAuthor function
#
# authorsID <- idByAuthor(df, api_key)
#

## extract the IDs

# id <- authorsID[,3]
#

## create the bibliographic collection

#
# M <- res$M  # the entire bibliographic data frame
# M <- res$authorDocuments # the list containing a bibliographic data frame for each author
