Non-book material:

1) Add the appropriate Harvard-mandatory form/genre term, coding as follows:
655 0|aAudiotapes.
655 0|aCD-ROMs.
655 0|aDVD-ROMs.
655 0|aDVD-Video discs.
655 0|aVideodiscs.
655 7|aVideotapes.|2local
More than one term from the above list may be required. (For the most up-to-date information, see the Bibliographic Standards Committee's list at http://hul.harvard.edu/cmtes/haac/Form_Gentre.htm). Other genre terms found in standard thesauri may also be added when needed.
2) For the Poetry Room modify the 852 subfield c as necessary, but still class in LC unless directed otherwise by the curator. Add 852 |z In library use. Code item status as In-library use (02).
Examples:

bPOE	cVID[videotapes]
bPOE	cCASS[cassette tapes]
bPOE	cDVD[DVD]
bPOE	cDISC[sound disc] For Houghton non-book media the 852 is	c GEN At the present time CSS catalogs non-book media for Theatre. 4) For non-book media which cannot be used due to the lack of equipment , e.g., a floppy disc that cannot be used on current computers, add 852	z Inacessible; reformatting needed. 5) Write the call no. with a fine-tip magic marker on hard surfaces such as fronts of discs and write in pencil on paper labels and on any accompanying paper material, such as program notes. 6) Print out the records, insert in or tie to items. Note: There is a designation "POETRY AUDIO MT" [master tape], apparently for recorded Poetry Room readings, etc. These records (if we become responsible for creating them) may need special treatment.
