The dispersal of the Indo-European language family from the third millennium BCE is thought to have dramatically altered Europe’s linguistic landscape. Many of the preexisting languages are assumed to have been lost, as Indo-European languages, including Greek, Latin, Celtic, Germanic, Baltic, Slavic and Armenian, dominate in much of Western Eurasia from historical times. To elucidate the linguistic encounters resulting from the Indo-Europeanization process, this volume evaluates the lexical evidence for prehistoric language contact in multiple Indo-European subgroups, at the same time taking a critical stance to approaches that have been applied to this problem in the past.

Quite frequently I come across scanned books that are viewable for free online. For example, the publisher put them there (such as preview chapters), a library (old books from their collection that are in public domain), etc. Since I like hoarding data, and the online viewers that are used to present the book to me might not be very practical, I frequently try to download the books one way or another. This requires toying with the "inspect element" tool and various other methods of getting the images/PDF. Now, all that I access is what is, well, accessible; I don't hack into the servers or something. But - the stuff is meant to be hidden from the normal user. Does that act of hiding the material, no matter how primitive and easily circumvented, mean that I'm not allowed to access it at all?

I suppose ripping a public domain book is no big deal, but would books under copyright fare differently?

Mainly I'm asking out of curiosity, I don't expect the police to come visit me for ripping a 16th century dictionary.

Note: I live in EU, but I'd be curious to hear how this is treated elsewhere too.

Edit: I also remembered a funny trick I noticed on one site - it allows viewing PDFs on their website, but not downloading, unless you pay for the PDF. But when you load the page, even without paying, the PDF is already downloaded onto your computer and can be found in the browser cache. Is it legal to simply save the file that is already on your computer?
