 Wanted to import the [Library of Congress record](https://lccn.loc.gov/83020232) for my Webster's dictionary.
 It failed with an obscure message (*notices invalides*). Looking at the code, this could be caused by a missing title statement (UNIMARC tag `$200a`).
 And indeed upon inspection the title is in MARC zone `$245`:

+PMB can query the Library Of Congress Z39.50 server. However the built-in configuration references an old server than no longer exists:
+
+* Nom : `Library Of Congress`
+* Utilisation : `CATALOG`
+* Base : `Voyager`
+* URL : `z3950.loc.gov`
+* Numéro de port : `7090`
+* Format : `USMARC`
+
+Instead the following configuration can be used:
+
+* Nom : `Library Of Congress (new)`
+* Utilisation : `CATALOG`
+* Base : `LCDB`
+* URL : `lx2.loc.gov`
+* Numéro de port : `210`
+* Format : `USMARC`
+
+and it works just fine.
+
+The default attribute mapping can be left as-is:
