cities <- tibble::tribble(
  ~city,
  "Berlin",
  "Darmstadt",
) %>%
  dplyr::mutate(related = get_page_related(city))
cities

# Unest to get one row per related page:
tidyr::unnest(cities, "related")

# The functions are vectorised over title and language
# Find all articles about Joanna Baillie, and retrieve summary data for
# the first two.
