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>

<h2>Virtual libraries</h2>
<p>With <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>
<p>More information and examples are available in the
