Easy access to the Project Gutenberg catalog and books

gutenberg-books

Easy access to the entire Project Gutenberg catalog + book downloading

A lightweight, modern Python library that lets you explore 70,000+ public-domain books from Project Gutenberg with zero hassle.

• Search by subject, author, language, title, or year
• Weighted random sampling (realistic distribution)
• One-line book downloading with automatic caching
• Fully offline after the first run

Installation

pip install gutenberg-books

Quick Start

from gutenberg_books import GutenbergBooks

# Initialize (downloads ~12 MB catalog on first run and caches it)
gb = GutenbergBooks()                    # default cache: ./GutenbergBooks

# Top 5 most common subjects / authors
print(gb.topn_subjects(5))
print(gb.topn_authors(5))

# Random books (weighted by popularity)
print(gb.random_books(n=3, seed=42))

# Search examples
pride = gb.search_books(subject="Pride and Prejudice")
print(pride[["Title", "Authors", "Language"]].head())

# Books whose authors were alive in a specific year
print(gb.books_matching_year(1813))   # e.g., year Jane Austen was writing

# Download a full book (plain text)
gb.download_book(1342)   # Pride and Prejudice – Jane Austen

All returned data are pandas DataFrames — easy to filter, export to CSV, or analyse further.
