My Amazon (Kindle) Library Ebook Lookup & Download

Overview

Note: This skill is meant for my own licensed content. It does not bypass DRM. If a title can’t be downloaded in an accessible file format, use Amazon’s official reading/export options instead.

Prerequisites

1. Have access to their Amazon (Kindle) library (purchased titles / content library)
2. Set their API key/token:

   export LIBRARY_KEY="your-key"

LIBRARY_KEY

When to Use

• User asks to find/download a book from their Amazon library
• Need to look up content from a published book they own
• Searching for a specific edition or format that exists in their library
• "Get me the PDF of Clean Code (from my Kindle library)"
• "Find the latest edition of Design Patterns (that I own)"

Quick Reference

python3 scripts/library.py search "query" --format pdf

python3 scripts/library.py details <md5>

python3 scripts/library.py download <md5> --output /path/

python3 scripts/library.py search "title author" --verify "expected title"

Environment Setup

export LIBRARY_KEY="your-membership-key"

Workflow

digraph download_flow {
    rankdir=TB;
    node [shape=box];

    search [label="Search by title/author"];
    verify [label="Verify correct book\n(check title, author, year)"];
    multiple [label="Multiple editions?" shape=diamond];
    prefer_recent [label="Prefer most recent\nunless specific edition requested"];
    format_ok [label="Preferred format available?" shape=diamond];
    download [label="Download via fast API"];
    convert [label="Use ebook-extractor\nto convert to text"];

    search -> verify;
    verify -> multiple;
    multiple -> prefer_recent [label="yes"];
    multiple -> format_ok [label="no"];
    prefer_recent -> format_ok;
    format_ok -> download [label="yes"];
    format_ok -> search [label="no - try different format"];
    download -> convert;
}

Common Patterns

Find and download a book

# Search with format preference
python3 scripts/library.py search "Clean Code Robert Martin" --format pdf --limit 5

# Verify it's the right book, get details
python3 scripts/library.py details adb5293cf369256a883718e71d3771c3

# Download
python3 scripts/library.py download adb5293cf369256a883718e71d3771c3 --output ./books/

Handle multiple editions

1. Check year - prefer most recent unless user specified edition
2. Check format - match user's preference (pdf/epub)
3. Verify author matches exactly

Format Priority

pdf > epub > mobi > azw3 > djvu

Converting to Text

1. Download with this skill →

   books/Clean_Code.pdf

2. Convert with ebook-extractor →

   books/Clean_Code.txt

Mirror Fallback

• library-archive.org (primary)
• library-archive.li
• library-archive.se
• library-archive.in
• library-archive.pm

Using mirror: <domain>

Error Handling

• "Invalid md5" - MD5 hash is malformed or doesn't exist
• "Not a member" - Key is invalid or expired (i.e., your Amazon-library access token isn’t valid)
• No results - Broaden search terms, try author-only search
• "Could not connect to any mirror" - All mirrors are down, try again later

Troubleshooting

SSL Certificate Error on macOS

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate

1. Install certifi:
   bash

   pip3 install certifi

2. Find your certificate path:
   bash

   python3 -c "import certifi; print(certifi.where())"

3. Add to

   ~/.zshrc

   :
   bash

   export SSL_CERT_FILE=/path/from/step/2/cacert.pem

4. Reload shell:

   source ~/.zshrc

python3 -c "import urllib.request; urllib.request.urlopen('https://google.com')"
