+# Comic Books Tiny Dataset v0 - Books (Testing)
+
+**Small test dataset of book-level metadata for rapid development and testing.**
+
+⚠️ **This is a TINY dataset** for testing only. For production, use `comix_v0_books`.
+
+## Dataset Description
+
+- **Total Books**: Unknown
+- **Format**: WebDataset (tar files)
+- **Content**: Metadata only (NO images)
+- **License**: Public Domain (CC0-1.0)
+- **Purpose**: Fast testing and development
+
+## What's Included
+
+Each book has:
+- `{book_id}.json` - Book metadata with page references
+
+## Purpose
+
+This dataset provides book-level metadata to group pages from **comix_v0_tiny_pages**.
+
+**Workflow**:
+1. Download `comix_v0_tiny_pages` (with images)
+2. Download `comix_v0_tiny_books` (metadata only)
+3. Use WebDataset pipeline to group pages by book
+
+## Quick Start
+
+```python
+from datasets import load_dataset
+import json
+
+# Load tiny books dataset
+books = load_dataset(
+    "emanuelevivoli/comix_v0_tiny_books",
+    split="train",
+    streaming=True
+)
+
+# Iterate through books
+for book in books:
+    book_data = json.loads(book["json"])
+    
+    book_id = book_data["book_id"]
+    total_pages = book_data["book_metadata"]["total_pages"]
+    
+    # Get page references
+    for page_ref in book_data["pages"]:
+        page_id = page_ref["page_id"]
+        dataset = page_ref["dataset"]  # "comix_v0_tiny_pages"
+        tar_file = page_ref["tar_file"]
+        files = page_ref["files"]  # json, jpg, seg.npz (if available)
+    
+    print(f"Book {book_id}: {total_pages} pages")
+```
+

+
+## Data Splits
+
+| Split | Books |
+|-------|-------|
+| Train | Unknown |
+| Validation | Unknown |
+| Test | Unknown |
+| **Total** | **Unknown** |
+
+## Use Cases
+
+✅ **Testing**: Rapid iteration on book-level structure
+✅ **Development**: Quick validation of page grouping
+✅ **Debugging**: Small dataset for troubleshooting
+✅ **Prototyping**: Fast experimentation
+
+❌ **NOT for**: Training production models
+
+## Version 0 (Primordial)
+
+This is a **primordial v0** with:
+- ✅ Basic structure
+- ✅ Page references
+- ⏳ Empty `book_metadata` fields (to be populated in v1)
+- ⏳ Empty `segments` (to be added in v1)
+- ⏳ Empty `characters` (to be added in v1)
+
+**Future (v1+)** will include:
+- Bibliographic information (series, issue, publisher)
+- Story segments with summaries
+- Character banks with appearances
+
+## Companion Dataset
+
+**comix_v0_tiny_pages**: Individual pages with images
+
+## Full Dataset
+
+For production use: **comix_v0_books** (~19K books)
+
+## Example: Group Pages by Book
+
+```python
+# Load both datasets
+pages = load_dataset("emanuelevivoli/comix_v0_tiny_pages", split="train")
+books = load_dataset("emanuelevivoli/comix_v0_tiny_books", split="train")
+
+# Create page index
+page_index = {p["json"]["page_id"]: p for p in pages}
+
+# Get a book and its pages
+book = books[0]
+book_data = json.loads(book["json"])
+
+book_pages = []
+for page_ref in book_data['pages']:
+    page_id = page_ref['page_id']
+    if page_id in page_index:
+        book_pages.append(page_index[page_id])
+
+print(f"Book {book_data['book_id']}: {len(book_pages)} pages loaded")
+```
