## Dataset Creation

### Curation Rationale
The dataset was created to provide a comprehensive index of all SEC EDGAR filings, enabling research, analysis, and monitoring of corporate financial disclosures and regulatory compliance.

### Source Data

#### Data Collection and Processing
- Data is collected from SEC EDGAR quarterly master files
- Processing includes structuring the data into a consistent format
- URLs are standardized to SEC.gov domain
- Timestamps are standardized to a consistent format
- Unique identifiers are assigned to each record

#### Who are the source data producers?
- Primary data producers are publicly traded companies and other entities required to file with the SEC
- Data is collected and distributed by the U.S. Securities and Exchange Commission

### Personal and Sensitive Information
The dataset contains only publicly available information from SEC filings. While it includes company names and identifiers, it does not contain personal information beyond what is already public in SEC filings.

## Bias, Risks, and Limitations

- Historical data may be incomplete for earlier years
- Company names may change over time
- CIK numbers may be reused in rare cases
- Form types may be deprecated or changed over time
- URLs may become invalid if SEC changes its archive structure
- Coverage limited to SEC-regulated entities

### Recommendations

- Verify current company information through SEC's current EDGAR system
- Cross-reference CIK numbers when tracking companies over time
- Consider form type changes when analyzing historical patterns
- Implement appropriate error handling for URL access
- Use appropriate date ranges for analysis based on regulation changes
- Consider regulatory context when analyzing filing patterns
