Preserved from prior description (commit c2cdbed6):

|
|
|
Permission specification for photography in reading rooms or collection areas.
|
|
**DEFINITION**:
|
|
A policy specification indicating whether researchers may photograph
|
|
materials for personal research use when consulting collections.
|
|
**SCHEMA.ORG ALIGNMENT**:
|
|
Maps to `schema:LocationFeatureSpecification` as it describes a feature
|
|
or amenity availability at a location.
|
|
**TYPICAL CONDITIONS**:
|
|
- Personal research use only
|
|
- No flash photography
|
|
- No tripods
|
|
- Some materials excluded (fragile, copyright)
|
|
- Declaration/waiver may be required
|
|
**COPYRIGHT CONSIDERATIONS**:
|
|
Photography permissions typically apply to:
|
|
- Public domain materials
|
|
- Materials where institution holds rights
|
|
- Personal research use (fair use/dealing)
|
|
Materials still under third-party copyright may have different rules.
|
|
**TEMPORAL SEMANTICS**:
|
|
Photography policies have evolved significantly:
|
|
- Pre-2000s: Generally prohibited, had to order copies
|
|
- 2000s-2010s: Gradual liberalization
|
|
- 2010s onwards: Many institutions allow free photography
|
|
