No Date: Indicates that no
Date of Publication is given in
the book. This phrase may be followed by a date in parenthesis giving the
Copyright Date which is not
indicative of when the book was published; or a date in braces [ ] which gives a date of publication,
or an estimate thereof, determined from sources other than those provided in the book.
No Place: Indicates that book does not disclose where
it was published. If the location of the printer is given, this may be information of interest,
but should not be regarded as the place of publication since the printer could easily be located
in another city or even country.
