Corrections to a stated status, a statute reference or a registration number are welcome, and so are pointers to a record we have not read.
Corrections
Name the piece and the shelf mark — the two-part number beside every title, such as 02.01 — and quote the sentence you are querying. A registration or renewal number, or the volume of the Catalog of Copyright Entries the entry appears in, makes a correction quick to check.
