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 Search Terms
Here are some terms you can use in OskiCat or Melvyl that may help you find books on your topic.
Remember, these search engines only let you search brief information about the books - you're not searching in the full text of the books themselves! If you're not getting enough results, try leaving out some search terms, searching for a less specific topic (Southeast Asian Americans instead of Cambodian Americans) using Google Books, or asking a librarian.
All of these terms are Library of Congress subject headings -- which means you'll get the most complete results if you enter them exactly as typed (African Americans, not African American).

You can use the Media Resource Center's website to browse for films on your research topic, or you can use OskiCat to find films and videos in the UC Berkeley Libraries. Enter your search terms in the "Keyword" box, like this:

Use the "Entire Collection" pulldown menu to restrict your search to "Films/Videos/Slides." Your search results may include online video as well as items in the Media Resources Center collection, or elsewhere in the campus libraries.

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 |
HathiTrust
HathiTrust (Hathi is pronounced hah-tee) is a partnership of libraries that works towards the goal of developing a shared digital access, preservation, and storage solution for the materials held in the member libraries. The contents of HathiTrust are similar to that of GoogleBooks, but the collecting focus is on scholarly materials and the resource includes content and features (such as indexing and manipulation of results) not available in Google Books.
Downloading PDFs
- To limit to “full view” (public domain materials) in your search, check the “full view only” box.
- From the “full view” of any item, click on Download whole book (PDF).
- Click login.
- Choose the University of California, Berkeley from the drop down list and click login.
- Enter your CalNet ID and passphrase.
- Click Download whole book (PDF).
- PDF will load and you will choose to either open it or save it.
- Phrase Searching: Use quotes to search an exact phrase: e.g., "occult fiction"
- Wildcards: Use * or ? to search for alternate forms of a word. Use * to stand for several characters, and ? for a single character: e.g., optim* will find optimal, optimize or optimum; wom?n will find woman and women.
- Boolean Searching: Use AND and OR between words to combine them with Boolean logic: e.g., (heart OR cardiac) AND surgery will find items about heart surgery or cardiac surgery.
- Phrase Searching: Use quotes to search an exact phrase: e.g., "occult fiction."
- Multiple Term Searching: When your search terms are not quoted phrases, avoid common words (such as: 'a', 'and', 'of', 'the', etc.) to speed up your search.
- Boolean Searching: Use AND and OR between words to combine them with Boolean logic: e.g., heart OR cardiac will find items containing the word heart or the word cardiac; heart AND cardiac will find items containing both words. Use a minus (-) to remove words from the result e.g., heart -cardiac will find items containing the word heart that do not include the word cardiac.
Creating Collections
- On the Collections page, click on login.
- Choose the University of California, Berkeley from the drop down list and click on login.
- Enter your CalNet ID and passphrase.
- Click on Create a New Collection and name your collection (the description is optional).

- Click on Add.
In the future if you want to edit, change the private/public setting, or delete the collection, your collections will always be listed in the "My Collections" tab whenever you are logged in to HathiTrust.
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:
