I have scanned some of the very old books I had (which are unlikely to be published as e-books in the near future) and am looking for a tool to keep track of them (and hopefully add some additional metadata which is not possible to add directly into the files).
Calibri, I guess, is the first tool that comes to mind. But its strict folder structure renders it unusable to me. I want to keep all my files in a folder (or construct my own structure, but I don't want the hierarchical structure dictated by a Calibre). Here are some initial requirements:
The tool is able to:
- Scan a folder and index all the PDF files in that folder
- (Optional) Parse the metadata of the PDF files
- Keep additional metadata entered by the user (fetching from web s also OK, but for the books I have I doubt it will be of any use)
- (Optional) Update relevant metadata according to user input
Support for no other file format is required. Ideally the tool should be free software (as in freedom).
Any suggestions?
