Ensure that long PDF documents incorporate bookmarks to facilitate easy navigation.

## What this means

In the context of PDFs, bookmarks are navigational tools that act like an interactive table of contents. 
They allow users to quickly jump to specific sections, chapters, or points of interest within the document. 
This feature is particularly important in longer PDFs, where scrolling through the entire document to find 
specific information can be time-consuming and inefficient.

## Why it matters

1. **Accessibility**: For users with disabilities, especially those using screen readers, bookmarks provide a way to navigate through the document without having to linearly read through all the content.
2. **User Convenience**: Bookmarks significantly enhance the user experience by allowing quick access to different sections of the document.
3. **Efficiency**: In professional or academic settings, bookmarks help in referencing and reviewing long documents more efficiently.

## How to fix

1. **Identify Key Sections**: Determine the main sections or chapters of your PDF that would benefit from bookmarks.
2. **Create Bookmarks**: Use a PDF editing tool to create bookmarks at these key sections. Ensure that the bookmarks are clearly labeled to accurately reflect the content they link to.
3. **Organize Hierarchically**: If your document has sub-sections, consider creating a hierarchical structure in your bookmarks for better organization.

## Testing Methodology

Silktide scans the PDF to identify the presence of bookmarks in documents exceeding 21 pages.

WCAG guidelines do not specify how many pages are required to be classified as a
long PDF. Because of this Silktide treats PDFs of 21 or more pages as long.
This matches [Adobe Acrobat's](https://helpx.adobe.com/acrobat/using/create-verify-pdf-accessibility.html?trackingid=KACNN#Bookmarks)
interpretation.

### Limitations
- **Page Threshold**: Silktide uses a predetermined page count to trigger this check, which may not always align with the user's definition of a 'long' document.
- **Bookmark Relevance**: While Silktide can detect the presence of bookmarks, it does not assess their relevance or accuracy in representing the document's content.
