# Book Marker Dataset (book_marker_dataset)
## Overview
The `book_marker_dataset` splits entire books into manageable sections, using sequential markers to maintain continuity across book splits. Each book is divided into token-limited segments, with markers connecting the end of one section to the beginning of the next.
### Structure
Each entry consists of:
- **Book Segment**: A chunk of text from a book.
- **Sequential Marker**: The marker connecting this chunk to the next or previous one.
### Columns:
text: The column containing the current chunk of the book text.
label: The columns containing the sequential marker and the next chunk of the book
```json
{"text": "book_segment", "label": ["marker", "next_segment"]}
```
### Example:
```json
{
"book_segment": "America is again facing forward to the sea...",
"marker": "!1",
"next_segment": "!1 The ancient thrill of the wide salt spaces..."
}
```
