I wanted my Calibre collections to be available within Obsidian. So, I have moved my Calibre library inside the vault, and link the needed pdfs in notes. This way I can keep adding new books through Calibre, and dont have to open Calibre when needed access to PDFs or notetaking from PDFs. Can there be a ways in which I use the existing (or new) tags from Calibre to used as regular tags as we do in Obsidian. I understand that the information is stored in metadata.db SQLite file.
Also if we can automatically pickup the cover images.
This will be useful with dataview and related plugins to list PDFs.
