Thanks for the explanation chaley.
I have a few more questions, if you don't mind:
* What do you use tags for?
* What kind of a hierarchy do you use when you cateogrize genres? Do you first make the Fiction/Nonfiction distinction? such as Fiction.Mystery.foo, or would that make the tree too deep?
* How do you decide where a book goes to? Do you use any websites to help you find that out?
* What is the 'date' field used for in Calibre? Is that the date that the book was added to the library?
* In the 'published' field, do you put the date that this particular edition was published, or when the book was originall published (this is more relevant to classical books that have many new editions)
* Where do you keep track of which edition this book is? Do you add an extra column for that as well?
* Do you have a separate column for the translator of the book, or do you keep it together with the author? (as it happens by default)
* If I use these custom fields, such as Genre, Language, Translator... will I be able to display them on the web interface?
