Simple and super fast book searcher, create and search your personal library.#
Book Searcher can index metadata for over 10 million books in one minute and perform searches at a speed of 30 microseconds.
You can download various ebook formats, such as epub, mobi, pdf, and more, and also preview and read them online.
I have personally tested the search, reading, and download speeds, and everything is free.
