Book covers
The home page and the Books page load cover images from Springer Nature's image server (media.springernature.com). Your browser contacts that server when you open either page, or when it prepares one of them in advance because you are about to follow a link to it. No referrer is sent with these requests.
Server logs
The web server of the National Technical University of Athens may keep standard access logs under the University's own policies.
Links to other sites
Links to publishers, DOI resolvers and academic profiles take you to services with their own privacy practices.
