Step-by-Step Safety Guide: Protecting Your Library Data

Phase 1: Pre-Sync Preparation (30 Minutes)

Backup Everything
- Export your current library from all platforms
- Create cloud backups (Google Drive, Dropbox, iCloud)
- Take photos of physical shelves for insurance purposes
Audit Your Accounts
- List all platforms: Kindle, Audible, Apple Books, Kobo, physical shelves
- Check API access availability
- Verify login credentials with 2FA enabled
Choose Your Primary Hub
- Decision tree:
  - Digital-heavy? → Calibre
  - Physical + digital mix? → FuzzyCatalog
  - Social reader? → LibraryThing
  - iOS-only? → BookBuddy

Phase 2: Secure Syncing Protocol

Step 1: Enable API Access Safely

- Never share API keys via email or chat
- Use environment variables for self-hosted tools
- Rotate keys after initial setup
- Limit permissions to "read-only" where possible

Step 2: Metadata Standardization

Choose one metadata source (Open Library is most consistent)
Standardize author name format (Last, First)
Decide on genre/tag taxonomy before bulk import

Step 3: Test with Small Batch

Sync 10-20 books first
Verify metadata accuracy
Check for duplicates
Validate cloud backup created

Step 4: Bulk Import (The Safe Way)

Use ISBN where possible (most accurate)
For scanned books, manually verify ambiguous matches
Check for duplicate entries before final import
Monitor API rate limits (especially with free tiers)

Phase 3: Ongoing Protection

Monthly: Export data from primary tool
Quarterly: Verify cloud backups
Annually: Review connected apps and revoke unused access
Always: Keep physical shelf inventory updated
