Browsing by call numbers

Call Numbers @ the UNH Library

Most larger academic libraries use the Library of Congress (LC) classification system rather than the Dewey Decimal System.  With LC, each letter of the alphabet (or two-letter combination) stands for a broad subject area, like Q for science and T for technology.  A second letter provides a narrower topic:  environmental engineering call numbers start with TA or TD. Catalog searches help you to find materials that are not all in one place. E-books and print books are all in the UNH Library Catalog.

When you read a call number (we use the Library of Congress system), go line by line:


Note .W45 acts like a decimal number.  The W just keeps things in alphabetical order. So,  .W45 is shelved after .W427 and before .W5

A few call number examples to show general classifications:

  • GB621-628  Wetlands  (in general; not wetland restoration)
  • RA591-598.5  Water supply in relation to public health

  • TA170-171 & TD145-146     Environmental engineering & technology in general
  • TD1-1066 Environmental technology. Sanitary engineering
    • TD169-171.8 Environmental protection
    • TD172-193.5 Environmental pollution
    • TD194-195 Environmental effects of industries and plants
    • TD201-500 Water supply for domestic and industrial purposes
      • TD419-428 Water pollution

Remember, some books are available only online as e-books, so you won't see them on the shelves.
