Hi!<br>    I&#39;m cataloging my books, but there are some of them that I can&#39;t.All oh others are OK, but some..... I tried repetitively times catalog the books with error and it continues getting problem. Maybe should be a numerical sequence of ISBN?  <br>
<br>The error:<br><h1>Koha error</h1>
                                                <p>The following fatal error has occurred:</p> 
                        <pre><code>Can&#39;t call method &quot;as_usmarc&quot; on an undefined value at /usr/share/koha/lib/C4/Search.pm line 2388.<br></code></pre>
