The current templates were revised as a result of the RDA rules. The book template will have 3xx fields for 300, 336, 337, and 338:
Do not include 300 in order records (just delete the field), but leave the other 3xx fields in the preliminary record.
With regard to the 300 field, if you have the book in hand,
For the 300 subfields ‡b illustrations and ‡c cm, leave as is (to be filled in by cataloging). Under RDA cataloging rules, "cm" is not treated as an abbreviation, so leave it as without the period.
300 __ ‡a 329 pages : ‡b illustrations ; ‡c cm
300 __ ‡a 4 volumes : ‡b illustrations ; ‡c cm
300 __ ‡a volumes : ‡b illustrations ; ‡c cm
300 __ ‡a 1 volume (unpaged) : ‡b illustrations ; ‡c cm
300 __ ‡a 2 sheets : ‡b illustrations ; ‡c cm folded <"folded" is optional>
300 __ ‡a 1 portfolio (25 leaves of plates) : ‡b illustrations ; ‡c cm <counting the number of plates is optional; if the plates are unnumbered, the extent would have: 1 portfolio (25 unnumbered leaves of plates)>
Generally fields 336, 337, and 338 should be left as is. You can substitute sheet for volume in field 338 (rdacontent) if that is what you have in hand, but when in doubt, leave 338 as is.
Use a separate template for microfilm, which will have different values in 3xx. If you are handling a microfilm reproduction, include the pagination in parentheses if readily available; otherwise, 1 microfilm reel (or however many reels are in the set) is sufficient.
Not necessary for a preliminary records created in Orbis. Enter the series in the 830 field instead.
Search for the series title in ORBIS and, if necessary, in LCDB. If the series is represented by an authority record, use the form of the series title as it is found in the authority record (including capitalization) in the 830 field. Record volume numbering from the piece in hand in ‡v, but use the caption as found in the series authority 642 field. Record the ISSN (International Standard Series Number) in ‡x if present.
If the series is not represented by an authority record, but the series has been used in field 830 or 440 in a bibliographic record, use the name exactly as found in the bibliographic record field's 830 or 440 (including the capitalization). Record volume numbering from piece in hand in ‡v.
If the series is not represented by an authority record, and it has not been used in field 830 or 440 in a bibliographic record, record the series statement as it appears in the item in hand in the 830 field.
