ThreadText: # Calibre for metadata scraping
  
  (Asked by: username_0 on 2015-08-21)
  
  I'm looking for a way to do a very specific task in Calibre but maybe it's not the right software.
  
  I know there are plugins/functionality to automatically collect metadata for existing ebooks and to get information for fields such as Author, Title, Year of publication, Tags, all based on information taken from the file's name.
  
  Is there a plugin/way for Calibre to scrape a bit of the book and try to match it's contents with some book through some search engine? Basically I want it to automatically scrape metadata without being constrained to the file name.

  Yes, a calibre plugin could do that. Does one? Not that I know of!
  
  You could look at the Extract ISBN plugin (<http://www.mobileread.com/forums/showthread.php?t=126727>) for an example of pulling data out of the ePub, and any of the metadata search plugins for how to then use the information you've found in a web search.
