Wikipedia links to books &amp; Mir publishers
<p>In some pages there are links to books on archive.org, does anyone know if these links can be trusted when it comes to not violating copyright rules?</p>

<p>I am particularly interested in a book from "Mir publishers". This publishing company closed down, does that make its copyrights void or am I obliged to buy from the remaining copies?</p>

<p>Archive.org has two parts:</p>

<p>The first is the Wayback Machine, which shows you older versions of websites. If you found the book on the old version of a website through the Wayback Machine, it might be copyrighted.</p>

<p>Second, is Archive.org's collection of links. Those are the ones under the title "Top Collections at the Archive". Those should be copyright free and available to use. </p>
