<altformavail> Alternative Form Available

<altformavail> encodes information about copies of the materials being described. It should include the type of alternative form, significant control numbers, location, and source for ordering copies if available. If the described materials are copies, <originalsloc> should be used to encode information about the existence, location, and availability of the originals. Copied materials may also have <altformavail>, if alternative forms such as photocopies, and digital or microfilm reproductions are available.

<altformavail> is one of the elements which may be used within <archdesc>, <c>, <c01> … <c12>, and itself.
