• EP Environmental Protection Agency
• HE Health Human Services Dept.
• J Justice Dept.
• NAS NASA
• PREX Presidents Executive Office

• D 301.82/3St 8
• EP 1.766/4
• HE 20.3902K 73
• L 2.32495
• PREX 2.8998
• Y 4.J 89/2S.HRG.107-604

6
Bound volumes often have the number on the spine.

SUDOC (CON.)

• A SuDoc number is composed of two parts
• the stem which designates the issuing agency and
  publication series
• the book number which identifies each
  publication in the series as a unique item
• A colon () divides the two parts of the number.
  
• Example HE 20.821688
• Stem HE 20.8216
• Book number 88

8
SUDOC (CON.)

• It may help to think of the stem as representing
  the first line of the call number.
• The book number is the second line of the call
  number.

9
SUDOC (con.)

• Publications are first filed alphabetically by
  the initial letter(s)
• A 1.75 (Agriculture Dept.)
• AC 1.16 (Arms Control Disarmament
  Agency)
• AE 2.108 (National Archives)
• C 3.2 (Commerce Dept.)
• HE 1.28 (Health Human Services Dept.)

10
SUDOC (CON.)

• The number following the letter(s) is shelved
  numerically
• C 3.
• C 55.
• C 61.

11
SUDOC (CON.)

• The number following the period is a whole
  number, not a decimal
• HE 20.9 nine comes before
• HE 20.44 forty-four which comes before
• HE 20.221 two hundred twenty-one

12
SUDOC (CON.)

• The number following the colon () may begin with
  a letter or a number and is filed accordingly
  alphabetically or numerically.
• HE 20.402AD 2
• HE 20.402R 24
• Or
• HE 20.821617
• HE 20.821686

13
SUDOC (con.)

• Use the punctuation marks to break SuDoc numbers
  into smaller sections. Compare numbers section by
  section until something is different put in
  order according to the first difference
• Correct order
• Y 4. J 89/ 1 108/ 12
• Y 4. J 89/ 2 S.Hrg. 105- 74

14
SUDOC (con.)

• Another example. Once the first difference is
  found, there is no need to consider later
  sections of the number, if any.
• In correct order
• Y 4.H 81/3EL 2/9/2001
• Y 4.H 81/3EL 2/22

15
SUDOC (con.)

• When one number you are comparing has more
  sections than the other, nothing in a particular
  position comes before something in that same
  position.
• In correct order
• C 3.186 P-60/113
• C 3.186/2 989
• C 3.186/7 986
• C 3.186/7-3 970-987
• C 3.186/9 985

16
SUDOC (con.)

• The last element of a SuDoc number is sometimes a
  year but years before 2000 were represented by
  the last 3 digits of the year only
• Correct order
• HE 20.402D 34/986 (dated 1986)
• HE 20.402D 34/995 (dated 1995)
• HE 20.402D 34/2001 (dated 2001)

17
SUDOC (con.)

• When comparing years, letters, and numbers (that
  is when they fall in the same section of the
  call number) the order is (1) Years, (2)
  Letters, (3) Numbers. (Another way to say that
  is years before regular numbers, letters before
  numbers).
• Correct order
• A 1.35993 year
• A 1.35R 42 letter
• A 1.35R 42/995 letter/year
• A 1.35R 42/2 letter/number
• A 1.35321 number

18
SUDOC (con.)

• Another example of years before numbers
• Correct order
• A 13.28C 42
• A 13.28C 42/997
• A 13.28C 42/2
• A 13.28C 42/2/990
• A 13.28C 42/3

19
SUDOC (con.)

• Some stems, particulary in the Y 4.s, use both
  styles of numbering, some in combination. Look
  for the stem area and then find the sub-group
  that matches the style of number you are looking
  for.

20
SUDOC (con.)

• Y 4 example of multiple style groups
• Y 4.J 89/2 C 43/8/986 (letter group first)
• Y 4.J 89/2 96-62 (numbered group next)
• Y 4.J 89/2 S.hrg.103-284
  (senate hearing numbered group next)
• Y 4.J 89/2 S.prt.101-54
  (senate print numbered group last)

31
LOCATION OF SOMEMAJOR U.S. SETS

• Some large sets are shelved separately and do not
  have call numbers

32
LOCATION OF SOMEMAJOR U.S. SETS

• Census
• Publications that make up the decennial Census of
  Population Housing or the Economic Census are
  shelved in a separate Census Collection
• They are not shelved by SuDoc numbers but by
  Census name and then chronologically

33
LOCATION OF SOMEMAJOR U.S. SETS

• Congressional Serial Set
• Shelved at the beginning of the Ys by volume
  number.
• Unbound House Senate reports and documents are
  shelved immediately following the Serial Set
  these are eventually bound and become part of the
  Serial Set.

34
LOCATION OF SOMEMAJOR U.S. SETS

• Congressional Serial Set (con.)
• Unbound House Senate reports and documents are
  shelved alphabetically by series name, i.e. House
  Documents are first, then House Reports, then
  Senate Documents, etc.

35
LOCATION OF SOMEMAJOR U.S. SETS

• Congressional Serial Set (con.)
• Indexes catalogs give SuDoc nos. for unbound
  reports documents ranging from Y 1.1/3 - Y
  1.1/8
• There is a chart in the shelf area to help
  convert these SuDoc numbers to report/document
  type.
