Fold
Description
A fold represents one or more connected parts of a page that can move independently around a hinge or crease. This includes various types of folded elements such as fold-out maps, gatefolds, accordion folds, and pop-up mechanisms where panels are connected but can be positioned at different angles or configurations.
The key characteristic is that multiple parts remain physically connected along a fold line (hinge) but can be positioned independently, revealing different content or creating three-dimensional structures.
Examples
Common examples include:
- Flaps: Small folded sections that can be lifted to reveal hidden content underneath
- Accordion Folds: Multiple panels connected in a zigzag pattern, commonly used in Asian handscrolls or modern artist books
- Fold-out Maps: A large map folded to fit within a book that unfolds to reveal the full extent of the geographical area
- Gatefolds: Two panels that fold out from the center, often used for panoramic images or large diagrams
- Pop-up Elements: Folded paper structures that create three-dimensional forms when the page is opened
Instances
Yale: Jane Wodening and Stan Brakhage scrapbooks — single flap (images 11 & 12)
Two images show the flap closed and open; hinge is clearly defined and shot at similar angles for alignment.

Implementation Notes
When implementing digital representations of folds:
- Fold States: Represent multiple states (fully folded, partially unfolded, fully unfolded)
- Hinge Visualization: Show the connection point between folded elements
- Sequence: Define the order in which panels should be unfolded
- Viewing Options: Offer both animated unfolding and direct access to different states
- Composite Views: Provide a way to see all panels aligned as they would appear when fully extended
- 3D Representation: For pop-ups, consider using 3D models or perspective views to show the raised elements
Viewing Considerations
Different fold types require different viewing approaches:
- Single Fold-out: Show folded state, transition animation, and unfolded state
- Gatefolds: Allow progressive unfolding from center outward
- Accordion Folds: Enable sequential navigation through connected panels
- Pop-ups: Provide multiple angle views or interactive 3D models to show depth
