Field-by-Field Comparison of AACR2 and RDA
006 Field (Fixed Field Description)
Leader/18 Desc (Descriptive Cataloging Form)
§ i (mostly with ISBD punctuation, the same as AACR2’s end of field/subfield punctuation)
§ c (without ISBD punctuation)

§ t (for publication date and copyright date, even if the same year: , ©2011)

§ Use $z for an invalid ISBN, such as for a record for a print book that also has the ISBN for the online version. The ISBN for the electronic version would be considered invalid in a record for the print version of a title.
040 Field (Cataloging Source)
§ $a $b $c $d (no subfield e)
§ $a (cataloging source) $b (language of cataloging) $e rda $c (transcribing agency) $d (modifying agency)

§ Record copyright date also if publication date is inferred (put it in brackets). If both dates are the same, copyright date may be omitted for brevity or included if specificity is preferred.
§ Include larger jurisdiction as found, if on the resource; if supplying a larger jurisdiction, consult the list in Appendix B11.
§ Adjacent subfields do not share square brackets.
§ Example: [Place of publication not identified] : [Publisher not identified], [between 1800 and 1899?]
300 Field (Extent of Item)

300 vi, 55 p. : $b ill. ; $c 24 cm.
§ Spell out description: such as pages : illustrations ;
§ For size and extent, continue to use abbreviations such as in., hr., min., etc. (follow LC practice)
§ Add a period at the end of cm if a 490 field is present, but otherwise do no use a period in this position.
§ Use cm for all size measurements instead of inches; except, LC practice uses inches for discs and other audio carriers.

§ Use new fields: 336, 337, 338 (rda content, rda media, rda carrier)
§ Order of subfields: $a term $b code $2 type of term/code
§ Fields are repeatable, if needed, although only the primary content needs to be represented in these fields.
§ Record or add term in $a, but accept it rather than delete it if $b (code) is already present in the record.
§ Use the following term/codes in $2 in the 336, 337, and 338 fields respectively:
§ 336 $2 rdacontent
§ 337 $2 rdamedia
§ 338 $2 rdacarrier
Example for a monographic print item:
336 text $b txt $2 rdacontent
337 unmediated $b n $2 rdamedia
