After reviewing the content of the `datacard.md` file, it provides a general overview and intent behind creating the dataset, as well as some specifics about updates in version 2. It mentions that:

- The dataset is created primarily due to the requirement of a dataset of books that is both clean and comprehensive.
- The data was scraped using the Goodreads API.
- The dataset aims to contain promising features without redundancy.
- In V2, it is mentioned that information about the publisher and publication date is now included, and multiple authors are delimited by '/'.

No explicit issues are evident from this description related to the hint provided, so the next step is to inspect the `books.csv` file to identify any issues with specific rows as suggested by the hint. Let's move on to reading and understanding the structure of the `books.csv` file.Encountering an error while reading the `books.csv` file indicates potential rows related issue as suggested by the hint. Specifically, the error message:

```
ParserError: Error tokenizing data. C error: Expected 12 fields in line 3350, saw 13
```

This error message presents an issue with specific rows in the CSV file where the number of fields does not match the expected number, leading to a parsing error.

Hence, we identified the following issue according to the provided format:

```json
{
    "issue": "Unexpected number of fields in row of CSV file",
    "evidence": "Expected 12 fields in line 3350, saw 13",
    "description": "While attempting to read the 'books.csv' file, a parsing error occurred due to an unexpected number of fields in line 3350, where the file expected 12 fields but encountered 13. This discrepancy suggests a potential data entry error or a mismatch in the file's structure at the specified line, which goes against the standard CSV format and might lead to issues while processing the dataset."
}
```

To further investigate and validate the content of line 3350 and surrounding data, we will attempt to read the CSV with an argument to handle such errors, which will help us to confirm and better understand the nature of the detected issue.Upon successfully reading the `books.csv` file with error handling for bad lines, we identified multiple lines with the same issue of unexpected number of fields:

- Line 3350: Expected 12 fields but found 13
- Additional lines (4704, 5879, 8981) with similar issues

This further confirms our initial issue detection.

Given this evidence, we extend the initial issue report with additional details:
```json
[
    {
        "issue": "Unexpected number of fields in multiple rows of CSV file",
        "evidence": "Line 3350: Expected 12 fields, saw 13 | Skipping line 4704: expected 12 fields, saw 13 | Skipping line 5879: expected 12 fields, saw 13 | Skipping line 8981: expected 12 fields, saw 13",
        "description": "While attempting to read the 'books.csv' file, parsing errors occurred due to unexpected numbers of fields in lines 3350, 4704, 5879, and 8981, where the file expected 12 fields but encountered 13. These discrepancies suggest potential data entry errors or mismatches in the file's structure at the specified lines, which goes against the standard CSV format and might lead to issues while processing the dataset."
    }
]
```

This parsing error indicates possible formatting issues or incorrect data entry in the said rows, which would necessitate a review and potential correction to ensure data consistency and integrity.
