1 lis512 lecture 5 the MARC format control fields

2 MARC variable fields MARC fields have names that are, in fact, numbers. Each field name has three digits. It is always quoted with all three of them. So we say “field 005”, not “field 5”.

3 MARC subfields Each variable field can have a number of subfields. Each subfield has a name that is a lowercase letter or number. So we say “subfield b of field 453”.

4 MARC special variable fields Fields that start with 00 are for fields that are called “control fields”. Fields that start with 0 but not with 00 are called “numbers and code fields”. Fields that do not start with 0 are the main field we study in cataloging.

5 field indicators Each variable field other than those starting with 00 can have zero, one or two field indicators. The field indicator says something additional about the field.

6 control freakism Studying all the parts of the control fields will leave us to become control freaks. Therefore I will mention here only those fields that are required for a full record, but US national requirements.

7 field 001 “control number” This is the record identifier assigned to the MARC record by the organization that creating using or distributing the record. When you get a record from elsewhere you are allowed to move the 001 contents to fields – 035 system control number – 010 LoC control number – 016 National Bibliographic Agency control number and place your own number in 001

8 field 003 “control number identifier” This is the MARC code for the organization whose control number is in 001. You can find codes at c/organizations/. When you change 001, you have to change 003 too! I produce the record for CW Post as of on the next slide.

9 CW Post record id: code: NGvP, normalized: ngvp name: C. W. Post Center of Long Island University Variant name(s) : C. W. Post College Long Island University, C. W. Post Center Post Center Address: Northern Blvd. Greenvale, New York United States record created: :00:00 record modified:

10 our record I have applied to the Library of Congress for the record for the Palmer School. I read nothing from them and the record appears not to have been created. Therefore we use “lis512” as our code for our organization. In FRBR terms, we are an organization.

11 005 “date & time of last transaction” This is the time of the last transaction on the record, of the form yyyymmddhhiiss where – yyyy is the year – mm is the month – dd is the day – hh is the hour – ii is the minute – ss is the second optionally, there can be a ‘.’ with fractions of a second. No time zone indication appears.

12 fields 006 and 007 These two fields – 006  “Fixed-Length Data Elements - Additional Material Characteristics” – 007  “Physical Description Fixed Field” are optional even in a full record, according to my interpretation of the national level full and minimal requirements I am leaving out further discussions of these.

13 field 008 This field has mandatory components but the mandatory nature depends on what type of material it is. I will first review mandatory fields for all types of materials. Bytes in a field are often reported as field/byte and we follow that here.

14 field 008 byte 0–5 It is the date “Date entered on file”. It is a six-character numeric string date, using the pattern using yy for the year, mm for the month and dd for the day. It indicates the date the MARC record was entered into the file. It is therefore never changed. When you enter a record into the catalog, change it.

15 008 byte 07–10 and byte 11–14 These are two dates, referred to as date 1 and date 2. Both of these dates are simple year numbers, i.e. following pattern yyyy. What they mean is encoded in the preceding byte, 008 byte 06 or 008/6 in short notation.

16 008/6 values, slide 1 ‘b’  Neither date1 nor date2 are given because one of them is a B.C. date ‘c’  both dates are for a continuing resource currently published. Here “Currently published” is defined as an item for which an issue has been received within the last three years. You enter the start date as date1 and 9999 as date2.

17 008/6 values, slide 2 ‘d’  ‘continuing resource ceased publication’  date1 is for the start year and date2 is for the end year. ‘e’  ‘detailed date’  date1 contains the year and date2 contains month and day, in that order. If the day in unknown, “uu” is used, if the day is not indicated “ ” is used for the day.

18 008/6 values, slide 3 ‘m’  ‘inclusive dates for a collection’  date1 is for the start year and date2 is for the end year. They may be the same year. ‘k’  ‘Range of years of bulk of collection’  date1 contains the year and date2 contains a year in which most of the collection lies in. ‘n’  ‘unknown dates’  date1 and date2 are not known. ‘p’  ‘date of distribution/release/issue and production/recording session’ in years.

19 008/6 values, slide 4 ‘q’  ‘questionable date’  date1 and date2 contain a start and end year range for a date of the item. ‘r’  ‘reprint/reissue date and original date’  date1 is for the reprint and date2 is for the year of the original. If not known it is ‘uuuu’. ‘s’  ‘unknown dates’  date1 and date2 are not known.

20 008/6 values slide 5 ‘t’  ‘Publication date and copyright date’  date1 contains the publication year and date2 contains the copyright year. ‘u’  ‘continuing resource status unknown’  date1 is for the start of the resource and date2 is ‘uuuu’. ‘|’  ‘no attempt to code’  the cataloguer is lazy.

21 what to do when we have choices Single part/multipart items complete in one year, use ‘b’, ‘r’, ‘e’, ‘s’, ‘p’, ‘t’, ‘q’, ‘n’ as the order of preference. Collections/multipart items complete in more than one year use ‘b’, ‘i’, ‘k’, ‘r’, ‘m’, ‘t’, ‘n’ as the sequence of preference.

22 008 bytes 15–17 place This is the place of publication, production, or execution. Use the codes that are in marc/countries/ If the code has only two positions, you fill the remaining position with a blank. If unknown use ‘xx ’, yes, with a blank. Use ‘vp ’, yes, with a blank for various places.

23 008 byte 35–37 language Three-character alphabetic code that indicates the language of the item. Choose codes from /languages/, or write – ‘|||’  no coding – ‘zzx’  no linguistic contents – ‘mul’  multiple, no predominant language – ‘sgn’  sign language – ‘und’  undetermined

24 008 byte 38 modified record It’s a code that indicates whether any data in a bibliographic record is a modification of information that appeared on the item being cataloged or that was intended to be included in the MARC record.

25 008/38 code values slide 1 ‘ ‘  ‘Not modified’  no modification ‘o’  ‘Completely romanized/printed cards romanized’  the bibliographic data in the MARC record is completely romanized and any printed cards produced are also in romanized form. ‘r’  ‘completely romanized/printed cards in script’  bibliographic data in the MARC record is completely romanized but the printed cards are available in the original script.

26 008/38 code values slide 2 ‘d’  ‘dashed-on information omitted’  MARC record does not contain “dashed-on” information found on the corresponding printed record, either because – the dashed-on information was input as a separate record – recorded in field 500 (notes, to be seen later) – or because it was omitted. “Dashed-on” information is generally the brief description of material related to a main item being cataloged that is not considered important enough to catalog separately. The "dashed-on" technique is rare.

27 008/38 code values slide 3 ‘s’  ‘shortened’  some of the data was omitted because the data exceeded a maximum character length ‘x’  ‘Missing characters’  the record contained characters that could not be converted to machine-readable form. Since most cataloguers prefer to romanize, value ‘x’ is rare. ‘|’  ‘No attempt to code’  cataloger lazy

28 008/39 slide 1 Byte 39 is the “cataloging source”. It indicates the original cataloging source of the record. Values are – ‘ ’  “National bibliographic agency”  creator of the original cataloging data is a national bibliographic agency – ‘c’  “Cooperative cataloging program”  the creator of the cataloging data is a participant in a cooperative cataloging program.

29 008/39, slide 2 More allowed values are – ‘d’  “other”  the creator of the cataloging data is a national bibliographic agency nor a participant in a cooperative cataloging program. – ‘u’  “Unknown” – ‘|’  “No attempt to code”  cataloger is lazy.

30 008 bytes 18–34 What is in those bytes depend on the form of the material. Within each form, there is a different coding. Since books are the most common, I cover all bytes required for a full record. For the other types, I only cover those bytes required for a minimal record. For computer files and mixed materials nothing is required for a minimal record.

31 008 byte 18–34 for books A book is when leader 06 contains code ‘a’ or ‘t’ and leader 07 is ‘a’, ‘c’, ‘d’, or ‘m’. Required for a full record are – 22 Target audience – 23 Form of item – 28 Government publication – 33 Literary form – 34 Biography

32 008 byte 22 for books This is the audience code. Values are – ‘ ‘  “unknown or not specified” – 'a'  “preschool”, age 0–5 – 'b'  “primary”, age 6–8 – 'c'  “pre-adolescent”, age 8–13 – 'd'  “adolescent”, age 13–17 – 'e'  “adult” – 'f'  “specialized” (a special case of adult) – 'g'  “general” (a special case of adult) – 'j'  “juvenile”, age 0 – 15 – '|'  “no attempt to code”

36 008 byte 33 for books (slide 1) This is the form of the literary form code. Values are – ‘0’  Not fiction (not further specified) – ‘1’  Fiction (not further specified) – ‘d’  Dramas – ‘e’  Essays – ‘f ‘  Novels – ‘h’  Humor, satires, etc.

37 008 byte 33 for books (slide 2) More values are – i - Letters – j - Short stories – m - Mixed forms – p - Poetry – s - Speeches – u - Unknown – | - No attempt to code

38 008 byte 34 for books This is the bibliography code. Values are – ‘ ’  No biographical material – ‘a’  Autobiography – ‘b’  Individual biography – ‘c’  Collective biography – ‘d’  Contains biographical information – ‘|’  No attempt to code

39 18–34 for maps Used when leader 06 is ‘e’ or ‘f’. Byte 25 for the type of cartographic material is required there. It can take value ‘a’  “Single map” ‘b’  “Map series”, i.e., the item described is a series of maps

40 008 byte 25 for maps Other codes are – ‘c’  “map” serial Issued in successive parts bearing a numeric succession code. – ‘d’  “globe” – ‘e’  “Atlas” (Includes atlas series, and serially issued atlases) – ‘f’  Separate supplement to another item

41 008 byte 25 for maps Other codes are – ‘g’  “Bound as part of another work” – ‘u’  “Unknown” – ‘z’  “Other”  None of the other defined codes are appropriate. – ‘|’  “No attempt to code”  cataloger lazy.

42 18–34 for music Used when leader byte 6 is ‘c’, ‘d’, ‘i’ or ‘j’. 008/20, “Format of music” is require for a minimal record. It takes the following values – ‘a’  “Full score” – ‘b’  “Full score, miniature or study size” – ‘c’  “Accompaniment reduced for keyboard” – ‘d’  “Voice score” – ‘e’  “Condensed score or piano-conductor score” – ‘g’  “Close score”

44 18–34 for continuing resources It means that leader byte 6 contains is ‘a’ and leader 07 is ‘b’, ‘i’, ‘s’. 008/34 the “entry convention” is required in a minimal record. It can take the values as follows – ‘0’  “Successive entry”  New bibliographic record is created each time a title changes a corporate body used as main entry or uniform title qualifier, changes This is the AARC2 way to do things.

45 008/34 values ‘1’  ‘Latest entry’  Cataloged under its latest (most recent) title or issuing body. This is pre- AARC. ‘2’  Integrated entry  Cataloged under its latest (most recent) title and/or responsible person or corporate body. This is used for integrating resources and electronic serials that do not retain their earlier titles. A new record is made only when there is a major change in edition or it is determined that there is a new work, and for title mergers and splits. ‘|’ - No attempt to code

46 18–34 for visual materials This is applicable when leader byte 6 is ‘g’, ‘k’, or ‘r’ Here, 008/33 “Type of visual” material is required. It can take values – ‘a’  “Art original” – ‘b’  “Kit” Mixture of components from two or more categories, that is, sound recording, maps, filmstrips, etc., no one of which is the predominant constituent of the item. – ‘c’  “Art reproduction”
