The gutenbergr package helps you download and process public domain works from the Project Gutenberg collection. This includes both tools for downloading books (and stripping header/footer information), and a complete dataset of Project Gutenberg metadata that can be used to find words of interest. Includes:
gutenberg_download() that downloads one or
more works from Project Gutenberg by ID: e.g.,
gutenberg_download(84) downloads the text of
Frankenstein.gutenberg_metadata contains information about each
work, pairing Gutenberg ID with title, author, language, etcgutenberg_authors contains information about each
author, such as aliases and birth/death yeargutenberg_subjects contains pairings of works with
Library of Congress subjects and topicsThis package contains metadata for all Project Gutenberg works as R datasets, so that you can search and filter for particular works before downloading.
The dataset gutenberg_metadata contains information
about each work, pairing Gutenberg ID with title, author, language,
etc:

The function gutenberg_download() downloads one or more
works from Project Gutenberg based on their ID. For example, we earlier
saw that one version of Persuasion has ID 105 (see the URL here), so
gutenberg_download(105) downloads this text.
