Clicking on that triangle will open the item and show the sub-genres, as you see with History and Science Fiction.Ĭlicking on a genre will search for all books with that genre or children of that genre. Genres containing sub-genres appear with a small triangle next to them. The genres themselves appear under that column. For example, assume that your genre structure is similar to the following:Įtc.By using the hierarchy feature, you can see these genres in the tag browser in a tree form:Īs you can see, in this example the outermost level (Genre) is a custom column. They don't provide a hierarchy.Ĭalibre's new hierarchy feature gives you the third, the ability to see the genres in a 'tree' and the ability to easily search for books in genre or sub-genre. The problem is that tags don't satisfy the third requirement. Many books can have the same tag, giving you the second. If you tag a book with the genre then you can use the tag browser (or search) for find the books with that genre, giving you the first. Subgroups (genres) must form a hierarchy subgroups can contain subgroups.This distinguishes subgroups from physical file folders. A book can be in multiple subgroups (genres).This is what distinguishes subgroups from user categories. A subgroup (e.g., a genre) must contain (point to) books, not categories of books.The commonly expressed requirements for subgroups such as genres are: Instead, I am talking about a way to display subgroups of books within a calibre library. Calibre's library file structure is not affected. I will use the genre example for the rest of this post.īefore I go on, please note that I am not talking about folders on the hard disk. Another wanted to keep track of gifts by subject and recipient.
One user asked for a way to organize textbooks by subject and course number.
The most common wish is to create genre hierarchies, but there are many others. Some people wish to organize the books in their library into subgroups, similar to subfolders. (Superseded by a section in the calibre manual.
