Types of Sources

At UHM Libraries there are seemingly endless choices when it comes to sources. It's important to know the various types of sources that exist and what their best intended use for your research papers will be. Most of the time you will be looking for scholarly and/or peer reviewed sources. For more information on finding credible sources see the Research Basics Page

For a breakdown on the many types of resources available and what information you can expect to find see Purdue Owl's Types of Sources guide.

Library Collections

After you've established what you need to look for it's time to start going through the UHM Library Collections.  You can find a list of collections are services here. See the library's Research Tools Guide to learn how to access these collections. Two valuable ways to search the library collections are Voyager and OneSearch.

Library of Congress Call Numbers

Once you find a book using the library catalog you'll need to find it on the self. You can think of a call number as a book's address on the shelf. The first line in a Library of Congress call number classifies the item by its subject according to the LC Classification System. The entire call number should be noted in order to locate the item.

  • LC call numbers are first arranged alphabetically, according to the letter or letters at the beginning of the call number, which correspond to the subject matter of the item. Example: Call numbers beginning with P are followed by PA, PB, PC, etc.
  • Within the alphabetical section, books are arranged by the number(s) that follow. Notice that these numbers are regarded as whole numbers. For instance, PS 1200 comes after PS 345. Example: QA 56 before QA 234 before QA 234.57 before QA 234.8
  • The next lines are alphabetic, then numeric as a decimal. The numerical part of this section is a decimal number, not a whole number. Use alphabetical order first, then the decimal extension to put the call numbers in correct sequence. (A3113 would come before A4, because 0.3113 is smaller than 0.4.) Example: HV 1431 .B7 before HV 1431 .B
  • Editions are often arranged by date or by the date and letters. Example: PS 3525 .I52 1971 before PS 3525 .I52 1973 before PS 3525 .I52 1973a
