Almost all the titles in my Calibre library are there because I have the book in electronic format.
A public library in my neighborhood is powered by
BiblioCommons.
I'd like to add a column(s) into my Calibre library with the following info
1. Is title part of the library's catalog? (Yes or No)
That's the most important question.
Other questions of secondary importance:
2. What's the status of the title (in, checked out, on hold)
3. If "in", is it available in my preferred branch?
4. If title is checked out, when is the estimated day of return (after all holds are done)?
