            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.</p>

            <p>For example you can use a Virtual Library to only show you books with the Tag <i>"Unread"</i>
            or only books by <i>"My Favorite Author"</i> or only books in a particular series.</p>

            <p>Using <i>virtual libraries</i> 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.</p>

            <p>For example you can use a Virtual Library to only show you books with the Tag <i>"Unread"</i>
            or only books by <i>"My Favorite Author"</i> or only books in a particular series.</p>
