If you're hunting around for where to read 'Oops, I Faked My Way Into Nobility' online, I usually start by checking the legal storefronts and the author/publisher's pages first. E-books often show up on Amazon Kindle, BookWalker, Kobo, and other major retailers when a work gets an official English release, and those platforms will often list whether a print edition exists. I like buying official releases when they exist because the translation quality is generally higher and it directly supports the creators; I once found a hard-to-track title that way and felt great about supporting the original author.
If an official English release hasn't been announced, my next stop is NovelUpdates. It doesn't host chapters, but it aggregates translation projects and links to the original and translated sources—so you can see whether a fan translation is active or if the novel is officially licensed somewhere. For web novels specifically, platforms like RoyalRoad or Webnovel sometimes host original or translated serializations, and authors will often post links from their personal blog, Twitter, or Pixiv. Libraries and apps like Libby/OverDrive are also worth checking; some publishers make digital copies available through them, and I’ve borrowed rare translated volumes that way.
For manga adaptations, if one exists, official platforms such as MangaPlus, ComiXology, or publisher stores are safest. Scanlation sites and sketchy free-reading pages can be tempting but often harm creators; I try to avoid them when a legit option exists. Personally, the thrill of finding a legal scan or grabbing a Kindle edition beats reading from shady sites—plus I sleep better knowing the folks who made it are getting paid.
