Preservation indicators state intended action toward care of the physical condition of materials and the maintenance or archiving of the intellectual content of information in print, electronic, or rather nonprint formats. From levels 1 through 5 protection of the collection from undue exposure to water, dirt, or abusive handling is assumed as the fundamental handling standard. Developing a preservation policy as a part of the collection management policy provides a basis for collection housing, retention, replacement, or binding decisions.

3 CONTENT PRESERVATION LEVEL/PLANNED REPLACEMENT
The intellectual content is preserved. The material may be kept in the original format or may be transferred to a more suitable or usable format. The original material may be discarded. Environmental conditions are maintained for the average conditions acceptable for most formats in the collection.
4 RESEARCH CONSERVATION LEVEL
