what does second impression mean in a book
Edition (book) Each batch of copies printed is termed a print run, printing run, printing, impression, or press run. This is all of the copies produced by a single set-up of the production equipment. One edition can have any number of print runs (i.e., first edition, first impression; first edition, second impression; second edition, first impression, etc.). Poor-selling books may have only one. Very successful books may have 50 or more. Older books (before about 1970) often noted the impression number among the publishing details. However, in printmaking each individual copy of a print is described as an impression.
