§ 256.4 - New revisions or replacement sets or series.

Where a publisher sells an industry product whose replacement or substantial revision is scheduled to be offered for sale within 1 year following the date of sale of the precursor work, such publisher should notify the purchaser, prior to consummating the sale, that the industry product will be replaced or revised and the approximate date of such replacement or revision. If the purchaser has not been so notified, the publisher should offer to the purchaser either:

(a) Full refund for the obsolete work within the 1 year period, less reasonable charges for the period of use of the work, or

(b) Full credit on the obsolete work within the 1 year period towards purchase of the new work, less reasonable charges for the period of use of the obsolete work.

Note:

This section does not apply when the publisher continues full supplementation of the precursor set or series.
