Bookoscope is a fast, searchable ebook catalog. With Bookoscope, you can browse your own self-hosted ebook library as well as download public domain classics from Project Gutenberg.
FEATURES:
- Fast
- Easy on the eyes
- Includes over 70,000 public domain books from Project Gutenberg
- Uses cached feeds (refresh on demand)
- Searchable by any available metadata
- Quick download and export to the ereader of your choice
COMPATIBLE WITH:
- Calibre-web
- Kavita
- Ubooquity
- Any ebook server with OPDS 1.0 functionality
WHY USE BOOKOSCOPE?
Some ereader apps can connect to OPDS endpoints, but the functionality is tucked away and awkward. There's no way to browse and search all the ebooks you have access to, all at once.
Bookoscope fills that niche. It crawls your OPDS endpoints, finds and caches all the books it can, and lets you easily download any of them to your device. From there, you can export them to your preferred ereader.
BOOKOSCOPE IS NOT:
- An ebook reader, sync client, or annotator, like Apple Books, Google Books, or Kindle.
- A metadata editor or organizer, like Calibre.
- A self-hosted ebook server, like Kavita, Ubooquity, or calibre-web.
Bookoscope may be used with any of the above, but is not affiliated with any other app or tool.
WHAT IS OPDS?
OPDS is the open standard for web endpoints that expose catalogs of ebooks. Many people use home OPDS servers for their personal ebook libraries.
WHAT IF I DON'T HAVE AN OPDS SERVER?
That's okay! You can use Bookoscope to browse and download free, completely legal books in the public domain. Start with classics like:
- Moby Dick
- Frankenstein
- Pride and Prejudice
- The Great Gatsby
- The complete works of William Shakespeare, Charles Dickens, Frederick Douglass, and more!}
