gutenberg-books 0.1.3

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)
• Polite book downloading with built-in delays (respects Gutenberg's robot policy)
• 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

# Explore the catalog
print(gb.topn_subjects(5))
print(gb.topn_authors(5))

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

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

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

# Download books (safe & polite)
gb.download_book(1342)                    # Pride and Prejudice
paths = gb.download_n_books(10, subject="Science Fiction", random_delay_sec=5)
paths = gb.download_size_books(size_mb=16, random_delay_sec=5)

All returned data are pandas DataFrames — easy to filter, save to CSV, or use in ML pipelines.

Main Features

Feature	Method	Description
Top-N lists	topn_subjects(n), topn_authors(n) etc.	Most frequent subjects, authors, languages, bookshelves
Weighted random	random_subjects(n, seed), random_authors(n, seed)	Realistic sampling
Search	search_books(...)	Multi-criteria search
Subject / Author filter	books_matching_subject(substr)	Case-insensitive
Year-based search	books_matching_year(year)	Authors alive in that year
Download single book	download_book(book_id, random_delay_sec=5)	Returns Path to file
Download multiple books	download_books(book_ids, ...)	List of IDs
Download by subject	download_n_books(n, subject, ...)	First N matching books
Download until total size	download_size_books(size_mb, ...)	Great for big-data test sets

Important: The download methods include random delays by default to respect Project Gutenberg's robot access policy.

Advanced Usage

# Use custom cache location
gb = GutenbergBooks(cache_dir="~/my_gutenberg_cache")

# Refresh catalog
gb.refresh_catalog()

# All unique values (pre-computed)
print(gb.all_subjects[:10])
print(gb.all_authors[:10])
