You can find some standards at the usual places for books etc. (LibGen has some), but if you are not in a hurry then scouring the Internet <i>very</i> thoroughly will usually yield results. Google won&#x27;t as easily show you as it used to, but careful queries and following leads through forums and such can bear fruit. You know you&#x27;re getting close when Google starts showing &quot;results removed due to DMCA&quot; messages and requiring you to enter a CAPTCHA &quot;because your search queries look unusual&quot; --- the latter may even be intended purposely as a form of discouragement, but persevere and eventually you will find what you&#x27;re looking for.<p>Then, once you&#x27;ve found a source, always remember to bookmark it and save a copy. They disappear from search indices quickly, despite the site still being around. It also helps to repeat your search periodically as sometimes the &quot;shifting sands can uncover treasure momentarily&quot; ;-)
