Gutenberg metadata about each work
Description

pg_rdf_to_json
function.
Usage
gutenberg_metadata

A tbl_df (see tibble or dplyr) with one row for each work in Project Gutenberg and the following columns:
- gutenberg_id
Numeric ID, used to retrieve works from Project Gutenberg
- title
Title
- author
Author, if a single one given. Given as last name first (e.g. "Doyle, Arthur Conan")
- author_id
Project Gutenberg author ID
- language
Language ISO 639 code, separated by / if multiple. Two letter code if one exists, otherwise three letter. See https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes
- gutenberg_bookshelf
Which collection or collections this is found in, separated by / if multiple
- rights

.txt
in Project Gutenberg for this record (as opposed to, for example, audiobooks). If not, cannot be retrieved withgutenberg_download

gutenberg_metadata
gutenberg_metadata %>%
count(author, sort = TRUE)
# look for Shakespeare, excluding collections (containing "Works") and
# translations
shakespeare_metadata <- gutenberg_metadata %>%
filter(
author == "Shakespeare, William",
language == "en",
!str_detect(title, "Works"),
has_text,
!str_detect(rights, "Copyright")
) %>%
distinct(title)
shakespeare_works <- gutenberg_download(shakespeare_metadata$gutenberg_id)
# note that the gutenberg_works() function filters for English
# non-copyrighted works and does de-duplication by default:
shakespeare_metadata2 <- gutenberg_works(
author == "Shakespeare, William",
!str_detect(title, "Works")
)
# date last updated
attr(gutenberg_metadata, "date_updated")
