Oh, if you're hunting a legal copy of 'The Stranger' by Albert Camus, there are a few straightforward routes I usually tell friends about.
First, buying is the simplest: most major ebook stores sell a licensed edition — Amazon Kindle, Google Play Books, Kobo, and Barnes & Noble all typically carry translations of 'The Stranger'. Publishers like Vintage or Knopf (depending on your country and translator) list their editions on their sites, and buying there or through a retailer gets you a clean, legal PDF or ePub. Second, check your public or university library. Apps like Libby/OverDrive and Hoopla often have licensed ebooks and audiobooks you can borrow for free with a library card. Third, some digital libraries (Internet Archive/Open Library) offer lending copies under controlled digital lending; those are legal in many places but limited in quantity.
One extra tip: translations have their own copyright, so even if a French original were free somewhere, an English translation might not be. If you want a free legal copy, first confirm whether the edition you want is in the public domain where you live. WorldCat can help you hunt down which edition is available nearby. Happy reading — Camus feels different every time I revisit him.
