We noticed that the titles of engravings in our db sometimes didn't match the titles as shown in BNF catalogues; this led to some confusion when referencing the documents in articles. CC sent me a list of some of the BNF titles. This is what I've done:

• Where BNF titles are supplied, I've used them verbatim in the titleStmt/title, sourceDesc/biblStruct/title, and sourceDesc/biblStruct/title[@type="trunc"] elements. I have not created truncated versions of them, because few of them are all that long anyway.
• Where the BNF provided two titles, I have used them like this: Title one (Title two).
• Where the filename (and @xml:id) of the document did not match the title, I have created a new filename and @xml:id which does match the title (being a normalized, lower-case, truncated form of its first few words).
• For a few engravings for which CC didn't send me the BNF title, I have still normalized the filename and @xml:id. The aim here is to make it easier to find the XML document based on the title.
• Updated references to all documents which have changed throughout the collection.
