This Calibre plugin has been created to download metadata and cover image from Antikvarium.hu. It was abandonded 6 years ago and Antikvarium.hu site changed a lot. I fixed and updated to get work now.
Original post from https://www.mobileread.com/forums/showthread.php?t=194094 by Kloon: I must give credits to the original author, Daermond for making and publishing the initial plugin, but sadly he had abandoned it, so here I am taking over and fixing the errors that have popped up since.
Also, a big thumbs up for kiwidude, for sorting things out for me.
Can retrieve title, author, series, ISBN, comments, tags, publisher, year of publication, rating, language and a cover image Shows multiple results if possible (3 by default, can be 1-20) Search based on ISBN if present, otherwise based on title and/or author
Requires Calibre 0.8 or later. Tested with 126.96.36.199
Download the attached zip file and install the plugin as described in the Introduction to plugins thread. Note that this is not a GUI plugin so it is not intended/cannot be added to context menus/toolbars etc.
