About the Wenceslaus Hollar Digital Collection
Copyright / Request
In keeping with its mission the University of Toronto Library provides access to the digital materials included in the Wenceslaus Hollar Digital Collection. The images in the online collection are derived from works in the public domain.
Copyright and other rights in the digital images, underlying encoded metadata, indexing and display of the materials in the Wenceslaus Hollar Digital Collection are held by the University of Toronto Library. The images may be used for the purposes of research, private study, or general interest. For these purposes the images may be viewed and printed without prior permission.

The objective of the digital collection was to digitize and provide web access to the engravings of Wenceslaus Hollar. The project implementation can be divided into three separate processes: scanning, metadata creation and web access.
The scanning was done by the Collection Digitization Department, University of Toronto Libraries, on the Betterlight Super6K-HS digital camera system and the Xerox FreeFlow Scanner 665. The master images have been captured to the following scanning specifications:
|8-bit per channel of colour information (24 per pixel)|
Since the chosen standard for archiving generates large files (average file size 48 MB), the project team chose to convert the images to JPEGs for online delivery. The site provides users with 3 sizes of JPEGs -- a thumbnail for quick reference and two sizes for examination and usage. In order to balance the onscreen quality with the overall size of the download, JPEG images were created at a medium compression level.
The descriptive metadata was also saved in a relational database format. The descriptive metadata contains fields such as title, state, Parthey Pennington classification, dimensions and others that facilitate in the discovery and retrieval of information.
In 2017 the Wenceslaus Hollar Digital Collection was migrated from ColdFusion to Islandora. Click here to view a web archived copy of the original site.
