Calibre vs Koreader in our news:
2013. Calibre Server - access your book collection via the Internet

Probably you didn't know it, but Calibre includes the inbuilt web server - Calibre Content Server for remote library management. Besides it can download and send you the books by email. The Calibre server makes your ebooks available to the gadgets within your home or office wireless network. And if you can set up port forwarding on your router - you access your library from a remote location. You can set a password to restrict access. By default access is unrestricted. The content server lets you see the whole Calibre database on your device, which is great, although if you have a lot of books in your library - it can be slow and you have to keep hitting the “Next” button to advance to the next group of books hour after hour. Using this approach you are using the device to choose the books to download. This approach is effective if you’re just browsing your Calibre database looking for a book to download to your mobile device. But if you wish to use the search power of Calibre to locate books that meet specific criteria to download, then Calibre Server is useless. ***
