<h2>Bulk import</h2>

<p style="color:var(--pico-muted-color)">
  Upload a CSV or MARC file to add works and items in bulk. Use <strong>Dry run</strong>
  to validate without writing. Non-loanable columns in CSV are respected; MARC
  imports are standards-compliant and do not carry item-level state.

    Enrich from external source — for rows with an ISBN or UPC, fill in
    missing fields (cover, description, publisher, etc.) by looking up the
    record in Google Books / Open Library / MusicBrainz / TMDb. Adds one
    network request per row on first run (cached thereafter); keep off for
    fast bulk imports of clean data.

  <label>
    <input type="checkbox" name="preserve_barcodes" value="1">
    Preserve barcodes — use the barcode and accession number from each CSV
    row instead of minting new codes. Supplied barcodes must be valid
    Compendium 10 or 14-digit format; rows with invalid barcodes are
    rejected. Use when re-importing a catalog export to the same system.

  <label>
    <input type="checkbox" name="strict_encoding" value="1">
    Strict encoding — reject the file on any non-UTF-8 byte (CSV /
    LibraryThing only). Default is lenient: invalid bytes are replaced and a
    warning is shown.
