reformatted Reformatting actions, level 3

q

q

Create a surrogate; keep original (A surrogate is a copy that will be served to the user in lieu of an original that is either too precious, too fragile, or too great a security risk to serve except in circumstances that require use of the original. In most instances, the copy is of preservation quality, meeting nationally recognized standards or guidelines.)

Reformatting actions, level 2

q q

Copying duplicate fragile materials on unstable media (Unstable media are

intrinsically unstable, e.g., acidic paper or nitrate film—or are assembled or packaged in an unstable manner, e.g., substandard bookbinding or obsolete or proprietary or unsupportable software—or are no longer manufactured.) Reformatting actions, level 1

q

Replace materials that require obsolete equipment (Obsolete equipment is equipment that is no longer manufactured or distributed and for which parts are no longer manufactured or distributed or are new models or types of equipment that do not work to retrieve and “read” all the information on the original item, e.g., wax cylinders or 00018 PCs.)
