Calibre download metadata wrong book11/15/2022 ![]() I use that before every synchronisation, it works within a second for the 2200+ ebooks I have, because most of them don't change from sync to sync. My self answered question How can I keep a large number of EPUB files, managed in calibre, “polished” describes a solution for only updating those Ebooks whose metadata are out of date, and in parallel. Mostly because the files date-time-stamp change, even if the metadata was not updated, resulting in a resynchronisation of all the file but also because it takes more time than necessary and can cause notification overload in the system. However I cannot recommend indiscriminate polishing of all the Ebooks. Polishing the ebook updates the metadata in the file from the metadata.opf. The metadata.opf filecalib resides in the same directory as the book in your library, easily accessed by right-clicking the book in Calibre and then "Open containing folder" This file looks very much like the content.opf file found in an EPUB file, but is different and also exists and has the same format, when your ebooks are not in EPUB format. epub files for which the metadata has been updated by Calibre.Calibre writes the metadata in a seperate file metadata.opf. The method described in this answer only updates those. To resolve that problem you can use the find based solution by Simon, but that always updates all epub files. This is because polishing is done faster than the time a notification is displayed. If you are running on Linux with Gnome, the polishing of many (50+) books can overflow your notification application. If you only select "update metadata." you should get what you want in the EPUB files. Once you have added the button to the toolbar, you select EPUB books and then the "Polish books" button: Note that book polishing only works in ebooks in the EPUB and AZW3 formats. Polishing, unlike conversion, does not change the internal structure/markup of your book, it performs only the minimal set of actions needed to achieve its goals. The Google metadata download and News download plugins received. Then simply select the books you want to be polished and click the Polish books button. Several bugs were also fixed in Calibre 2.81 to improve the TXT Input, Get Books, E-book Viewer, Edit Book, and other components. To use this tool, go to Preferences->Toolbar and add the Polish books tool to the main toolbar. Calibre also has its drawbacks: The ugly and unfriendly interface. But nothing is purely perfect in this world. There are a lot of eBook lovers and developers contributing to this software and make it the household name in the ebook area. But you have to add the capability to the calibre interface: Calibre is a one-stop solution for eBook reading as an almighty and open-source software. You can "polish" your ebooks with calibre since version 1.0. ![]()
