Using call numbers to find books
Books and journals are arranged on our shelves according to the Library of Congress (LC) classification system. Each is assigned a unique call number based on its subject matter and other characteristics. Items on the same subject will often be grouped together.
In using a call number to locate a book on the shelf, consider each element in turn before moving on to the next segment.
These call numbers are arranged as they should appear on the shelves. In each case, the element shown in boldface distinguishes the number from the preceding one:
Each call number consists of several elements. For example::
The FIRST line, TK, is based on the broad subject of the book. Within Class T for technology, TK represents electrical engineering.
The SECOND line, 7881.6, defines the subject matter more finely. When looking for the book, read this as a whole number with a decimal component. In this example, TK7881.6 represents magnetic recording (a subdivision of TK— electrical engineering).
The THIRD line, M29, usually indicates author, but may also represent a further subject subdivision, geographic area, etc. There may also be a fourth line, formatted the same way. When looking for the book, read the numeric component as if it were preceded by a decimal point. In the example above, the numeric part of M29 should be read as ".29" (and the call number TK7881.6 M29 comes before TK7881.6 M4).
The YEAR of publication, such as 1993, may also be present. These file in chronological order and often indicate successive editions of a book. The call number may also have additional elements, such as volume numbers.
"I found a book - now what?"
You can check out books from most libraries on campus with your Cal 1 Card. Here's information on borrowing, renewing, returning, overdue materials, etc.
To find books, DVDs, maps, sound recordings, manuscripts, and much more - everything except articles - use a library catalog.
OskiCat = UC Berkeley libraries
MELVYL= all UC campus libraries, including all UC Berkeley libraries
What's the difference?
For each item make sure you know the name of the physical library, call number, and whether or not it's checked out, library use only, etc.
