The "Original Publication Date" shown in the metadata for an Ebook Central ebook refers to the date of this particular publication - not the date the book was originally published
. So, for example, even though the book Moby Dick
was first published well over one hundred years ago, the Ebook Central version is shown in the metadata with a publication date of 10/2009 – which is the date that this particular version with this particular forward, etc. was published - versus the date the book was first published, which was 10/1841.
