Audit Workflow
Phase 1: Book Selection
# Get all books
curl -s "https://sourcelibrary.org/api/books" | jq '[.[] | {id, title, author, year, page_count: .pages_count}]'
# Check what's already audited (search QAreport.md for book IDs)
Phase 2: Metadata Audit
For each book:
- •Fetch book data
curl -s "https://sourcelibrary.org/api/books/BOOK_ID" > /tmp/book.json
- •
Read title page (typically pages 1-5)
- •Extract: Title, Author, Year, Place, Publisher
- •Note printer's marks, dedications, privileges
- •
Compare against catalog metadata
- •Title: exact match vs normalized
- •Author: complete name, dates, alternate spellings
- •Year: from colophon or title page
- •Place: Latin name → modern equivalent
- •Publisher: full name, "widow of", "heirs of", etc.
- •
Check USTC alignment (when applicable)
- •Search: https://www.ustc.ac.uk/
- •Record USTC ID if found
- •Note any discrepancies
Phase 3: Translation Quality Audit
- •
Sample 20-30 pages spread across the book
- •Include: beginning, middle, end
- •Include: text-heavy pages, tables, marginalia
- •
Check for issues:
- •OCR copied instead of translated
- •Missing sections
- •Terminology inconsistency
- •Formatting problems
- •[Notes] accuracy
- •
Calculate quality percentage
- •100%: No issues
- •99%: 1-3 minor issues
- •97%: Multiple issues
- •<95%: Significant problems
Metadata Standards
Title
- •Use original Latin/vernacular title as primary
- •Include subtitle after comma if significant
- •Normalize "V" to "U" in display? (preference)
Author
- •Standard format: "Last, First (YYYY-YYYY)"
- •Multiple authors: Use pipe separator
- •Include: editors, translators, commentators
- •Note: "attributed to", "pseudo-" when appropriate

- •Signatures if available
Not in USTC
If book predates 1601 but not in USTC:
- •Note "USTC: Not found"
- •May indicate: rare edition, variant, or cataloging gap
- •Verify metadata from other sources

Rules (CRITICAL)
DO
- •Read title pages carefully (usually pages 1-5)
- •Check colophon for publication info (usually last pages)
- •Sample broadly across the book for translation quality
- •Record USTC IDs when available
- •Note anthologies/compilations with multiple authors
- •Credit editors and translators
- •Use consistent Latin → modern place name mappings
DO NOT
- •Make changes to the database (audit only, report issues)
- •Delete any records
- •Skip translation quality check unless explicitly requested
- •Assume metadata is correct without verification
- •Mark issues without specific evidence
Continuous Operation
- •After completing a batch, notify user and continue with next batch
- •Don't stop and wait - keep auditing until user says to stop
- •Update todo list as you progress
Common Issues Found
Metadata
- •Missing publisher/place (common in early imports)
- •Incomplete publisher info (one name instead of partnership)
- •Compilations attributed to single author
- •Missing editor/translator credits
- •Date format inconsistencies
- •Wrong categories (e.g., Copernicus marked as "alchemy" instead of "astronomy")
- •Language marked wrong for multilingual works
Translations
- •OCR copied instead of translated (image-only pages)
- •Damaged text markers not handled
- •Tables/lists formatting issues
- •Greek/Hebrew passages untranslated
- •Marginalia missed
- •Mistral-generated OCR may have catastrophic errors (prefer Gemini)
OCR Verification Audit
When verifying OCR pipeline:
Check Batch Job Status
# Get all batch jobs
curl -s "https://sourcelibrary.org/api/batch-jobs" | jq '.jobs | group_by(.status) | map({status: .[0].status, count: length})'
# Check specific book OCR coverage
curl -s "https://sourcelibrary.org/api/books/BOOK_ID" | jq '{
title: .title,
total: (.pages | length),
with_ocr: [.pages[] | select((.ocr.data // "") | length > 0)] | length,
with_translation: [.pages[] | select((.translation.data // "") | length > 0)] | length
}'
OCR Quality Indicators
- •Check for mixed-language handling (Latin + Greek)
- •Verify Fraktur/blackletter recognition (German texts)
- •Confirm special characters preserved (planetary symbols, Hebrew, etc.)
- •Note model used (Gemini vs Mistral) - Gemini preferred

Priority Queue
Audit in this order:
- •Original language texts - Verify authenticity, flag modern translations
- •Pre-1700 first editions - Highest scholarly value
- •Recently imported books (no audit yet)
- •High-visibility books (Agrippa, Fludd, Boehme)
- •Books with known metadata gaps
- •Google Books posters - Replace with book frontispiece
Google Poster Audit (FIX)
Mission: Find books with Google Books poster images and replace with the actual book frontispiece.
Detection
Google Books posters have thumbnail URLs containing books.google:
- •
https://books.google.com/books/content?id=... - •Any URL with
books.googlein it
API Endpoint
# List all books with Google posters
curl -s "https://sourcelibrary.org/api/admin/fix-google-posters"
# Fix a specific book
curl -X POST "https://sourcelibrary.org/api/admin/fix-google-posters" \
-H "Content-Type: application/json" \
-d '{"book_id": "BOOK_ID"}'
# Fix all books with Google posters
curl -X POST "https://sourcelibrary.org/api/admin/fix-google-posters" \
-H "Content-Type: application/json" \
-d '{"fix_all": true}'
Smart Frontispiece Detection
The API uses OCR text to find the actual title page:
- •Scans first 5 pages for publishing indicators (excudebat, typis, apud, anno, etc.)
- •Matches book title and author against OCR text
- •Selects the page that looks most like a title page
- •Falls back to page 1 if no match found
- •Uses
cropped_photo→archived_photo→photo(in priority order)
Workflow for Batch Fix
/qa-audit google-posters # Find and fix all Google poster books
Steps:
- •Call
GET /api/admin/fix-google-postersto list affected books - •Review the list
- •Call
POST /api/admin/fix-google-posterswith{"fix_all": true}to fix all - •Report results (shows which page was selected for each book)
Flag for Report
| Flag | Meaning |
|---|---|
FLAG:GOOGLE-POSTER | Book has Google Books poster (needs fix) |
FIXED:POSTER | Poster replaced with frontispiece |
