Searching Library Catalogs
Use OskiCat to locate materials related to your topic, including books, government publications, and audio and video recordings, in the libraries of UC Berkeley. OskiCat will show you the location and availability of the items that we own.
- Using OskiCat (but not Melvyl) you can also renew your books online, look up course reserve materials by course number or instructor name, and place holds on items that other library users have already checked out.
Use Melvyl to locate materials related to your topic located at other campuses in the UC system, or worldwide. You can use the Request button to request an item from another library, if we don't own it.
- Using Melvyl (but not OskiCat) you can find articles as well as books, easily format a citation for copying into a bibliography, and see images of book covers, when available. Melvyl will also show you the location and availablity of items that we own.
Melvyl has changed as of January 2012, and now includes many more articles. Detailed Melvyl help.
OskiCat Searching Tips
- Search for author's name using the author search: Auster, Paul
- Search for topics using a keyword search: labyrinth and borges
- Use an asterisk as a wildcard: author* finds authority, authorship, etc.
- Limit results by language (Modify search)
- You can browse topics using the Subject links. To find secondary literature on a particular author, look for "criticism and interpretation" subject links such as these:
Google Books
Google Books contains millions of scanned books, from libraries and publishers worldwide. You can search the entire text of the books, view previews or "snippets" from books that are still in copyright, and read the full text of out-of-copyright (pre-1923) books. Want to read the entire text of an in-copyright book? Use Google Books' Find in a Library link to locate the book in a UC Berkeley library, or search OskiCat to see if UC Berkeley owns the book.
Why use Google Books?
Library catalogs (like OskiCat) don't search inside books; using a library catalog, you can search only information about the book (title, author, Library of Congress subject headings, etc.). Google Books will let you search inside books, which can be very useful for hard-to-find information. Try it now:
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.
Each call number consists of several elements. For example, consider:
TK
7881.6
M29
1993
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.
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:
| Q 76 K26 |
QA 17 F75 |
QA 17.1 C98 |
TK 3 Z37 |
TK 29 M49 |
TK 29 M5 1997 |
TK 29 M5 2007 |
