+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`:
+

+Turns out that the LoC notice is in MARC21 format, whereas PMB expects UNIMARC.
+So I used [MarcEdit](https://marcedit.reeset.net/) to convert MARC21 to UNIMARC and was able to import.
+
+Conversion process: `Tools > UNIMARC Tools > MARC21=>UNIMARC`
