The scans are made at 1016 dpi grayscale and are available to you at a maximum resolution of 600 dpi.

Registration allows you to access the service at different levels of privileges established by the project partners of SISMOS and EuroSeismos.
Two different digital resolutions are available to users: a 200dpi preview and a 600dpi full-size.
The viewing and downloading of previews is allowed to all registered users, but files at 600dpi are:
