How to Find Gov Docs in Kraemer Family Library

The government documents collection in Kraemer Family Library is in a separate collection located on the second floor (see map below).

Records for many of our  government documents can be found in the library’s online catalog. You may search by author (personal or government agency), title, subject, keyword, or SuDoc number (call number). Some of our pre-2007 documents are not cataloged.  They can be found through the document shelf list (see map).  If you need assistance using the shelf list, ask at the Research Assistance desk or contact the  Government Documents Coordinator.

To find government documents in the collection, use the SuDoc numbers provided in the online catalog, the CGP, or the shelflist. Examples are HE 20.2002:B 52/8 and Y 4.C 43/2:H 75/2.  (Scroll down to  How to Find Documents Using SuDoc Numbers below.)  Microfiche and Maps are housed in special cabinets in the Documents area.  Prospector or Interlibrary Loan (Illiad) are available for requesting documents Kraemer Family Library does not own.

If you need assistance with the documents collection, contact the Research Assistance desk or the Government Documents Coordinator.

Please do not re-shelve documents you have looked at.  Place them in the return baskets located on top of the Gov Docs Shelflist cabinet.  If you have checked out a document, return it to the Circulation desk or to any of the Library's book returns.

How to Find Documents Using SuDoc Numbers

SuDoc classes are 1-3 letters based on the agency of government that produced the document. A=Dept. of Agriculture, C=Dept. of Commerce, D=Dept. of Defense, etc. 

SuDoc classes are arranged alphabetically. Then the number before the period is arranged numerically. The number between the period and colon is a whole number (ex. HS 1.2: comes before HS 1.15:). If that number is followed by / and another number, that number is also arranged in numerical order. 

The colon is the break between the SuDoc stem and its suffix. After the colon, the hierarchy of sorting is as follows:

Date –arranged in chronological order. NOTE: twentieth-century years are printed     without the initial 1. Hence 1989 is printed 989.

Letter –arranged alphabetically.   May be followed by a number arranged numerically.                           

Number other than years –arranged numerically.

Word –arranged alphabetically. These may be whole words or  abbreviations.


Both before and after the colon, an empty space will file before a space that has a letter or number (i.e. “nothing” before “something”).

How to Read Sudoc Numbers


How to Read Colo Doc Numbers

1. Read each alphabetic or numeric element within the call number moving from left to right. Concentrate on the numbers to the left of the period before moving on to the right.

2. To the left of the period, numbers without a slash go before numbers with a slash.  Numbers following the slash go in numeric order. 

3. To the right of the period, alphabetical elements go before numerical elements when they coincide in the sequence.

4. Dates are ordered chronologically.

5. Miscellaneous elements like vols. or pts. in publication numbers are filed in sequence. Numbers go before years.
