Windows 10 has native support for PDF, but if ePub is your preferred reading format then you’ll still need to find a third-party viewer.

Bibliovore is a good-looking eBook reader and manager app for Windows 8.1 and later.

The app imports individual ePub and PDF files, and can also scan and open the contents of a folder tree.

This initial indexing and library creation seems to have a bug or two, as the app hung when scanning one of our files. But once we removed that ePub, the program worked quickly and without issue.

Reading mode opens with a simple two-page view, Next and Back buttons.

There’s support for reading PDF and ePub files

Right-clicking displays a slider which you can drag to select a specific page. There’s also quick access to the book’s Table of Contents, a simple bookmarking system, and an option to view pages one at a time.

If the display isn’t quite right, you’re able to customise fonts, background and foreground colours, as well as setting Day or Night reading modes.

Basic library management tools allow you to edit metadata, search, view and organise your eBooks by authors, books, categories, series and more.

Bonus web features include the ability to keep your library on OneDrive, and browse/ download books from Project Gutenberg and Ebooks Gratuits.

This doesn’t always run smoothly. The app crashed when we ran some online library searches, returned poor matches for some, worked occasionally for others: we’ve no idea why.

Still, the program displayed all our test books without any problems, the OneDrive support is useful, and the 4-star rating suggests most users are happy.
