Using virtual libraries you can restrict calibre to only show + you books that match a search. When a virtual library is in effect, calibre + behaves as though the library contains only the matched books. The Tag Browser + display only the tags/authors/series/etc. that belong to the matched books and any searches + you do will only search within the books in the virtual library. This + is a good way to partition your large library into smaller and easier to work with subsets.
+ +For example you can use a Virtual Library to only show you books with the Tag "Unread" + or only books by "My Favorite Author" or only books in a particular series.
