# SuDocs Shelving Tips

## Federal Documents

**1. Letters before Numbers: **

If both letters and numbers are used for the same class number, shelve letters before numbers.EXCEPTION: S.HRG. AND S.PRT. are filed by session of Congress

Here is the shelving sequence:

Y 4.J 89/1:AD 65

Y 4.J 89/1:104/23

Y 4.J 89/2:C 55/2

Y 4.J 89/2:98/52

Y 4.J 89/2:S.HRG.104-374

**2. Whole numbers not decimals: **

Sudocs is not a decimal system, it's a whole number system.

Here is the shelving sequence:

HE 20.40:

HE 20.108:

HE 20.3016:

**3. Stem numbers first: **

Look at stem number first (before colon), then proceed with remainder of SuDoc No.

Here is the shelving sequence:HE 20.3612/3:

HE 20.3612/3-2:

HE 20.3612/4:

**4. Treat all numbers numerically: **

This includes numbers and years.

This means numbers and years are filed numerically dependidng how they appear in the call number. In the past, the GPO dropped the "1" in the year (eg 952, or 998 instead of 1952 or 1998). Since the year 2000, they began assigning the entire year in the SuDoc number (eg. 2003 or 2005).

Here is the shelving sequence:

ED 1.2:IN 8/2

ED 1.2:IN 8/965
