Any materials digitized for the Nickels and Dimes must adhere to the following minimum requirements. Any divergences from these minimum requirements will be documented in the project's specifications.

|B&W Text with Illustrations||8-bit||Grayscale||400dpi||100% (1:1)||TIFF (uncompressed)|

- Materials are handled as little as possible and stored in a secured location when not in use.
- Bound materials are scanned lying flat.
- Scanning of tightly-bound materials occasionally requires removing the binding, which is done in consultation with the Project Manager and Content Provider.
- Glass is used to flatten pages for scanning, but only when it poses no danger to the materials.
- Uncut book edges will be cut by scanning technicians, unless otherwise requested.
- Materials are handled with clean, bare hands, unless otherwise requested.
- Scans will include an archival border.
- Displayed images are .jpg derivatives of .tiff master files.
- Items are selected based on completeness of the collection and earliest printing.
- When multiple copies of the item exist in collection, the earliest printing is the preferred scanning document.
- At times, multiple copies of the same work may be scanned to show differences in printings, or if a more significant version is found at a later date.
