PSYC 201: Research Methods: About the Libraries

Dinand Library

The front of Dinand Library at sunsetAs part of a post-World War I campus expansion, Dinand Library was originally designed by the Boston architectural firm of Maginnis & Walsh to be a defined space for study on the campus. Named in honor of Bishop Joseph N. Dinand, S.J. who served as President of Holy Cross from 1911-1918 and from 1924-1927, the library was dedicated in 1927 and renovated in 1979 when the Hiatt wings were added.  Dinand Library is located at the center of campus and is the main campus library.

Call Numbers & Locations


If the call number
begins with....
Go to: 
A - G Dinand Stacks, Mezzanine (Upper) Level
H - L  Dinand Stacks, Ground (Lower) Level
M Music Library
N, TR Dinand Visual Arts Wing, Main Level
P Dinand Stacks, Ground (Lower) Level

Oversize Books

If a book is listed as being located in one of the following locations...

Dinand Library Oversize
Music Library Oversize

OR, if the call number includes a plus sign (+) -- for example, B2294 +G34 2011 --, it means that the book is taller than normal and had to be stored separately, in the oversize section. Oversize books are located at the end of each letter section. For example, you would find the call number above between the 'normal' B section and the start of the C section. Some call numbers have a ++, and will be found between the + section and before the start of the next letter section. There is no oversize section in the Science Library. 

To see our online journals, visit the EJournals Search.

Recent journals and newspapers in print are located in the Dinand Main Reading Room.
These are organized A-Z on the left side of the Main Reading Room (opposite the patio). 

The Science Library keeps new journals (unbound, single issues of journals published in the current calendar year) organized A-Z in the front (East) end of the library. Older issues are bound together into hard cover volumes. These bound journals, as well as single issues of journals published previously to the current year, are located in the back (West) end of the Science Library.

Recent periodicals in the Music Library are stored A-Z on the periodical shelf, for easy reading. Back issues of each journal are stored behind the displays. 

At Holy Cross, we organize our books using a system called Library of Congress Classification or LCC. LCC is based on the subject of the books. Each letter represents a specific subject. Each subject is broken down into more specific letter sections, each of which is further broken down into number ranges for specific topics. For example: 

  • P is the area for languages and literature, and has subsections from PA to PZ covering the study of language and the literature of different languages and cultures. 
  • PR is the section for English language literature. 
  • PR750 to PR890 is the number range for English prose literature.

You will also see extra numbers and letters on the end of most call numbers, which are based on things like the author’s name. We use these to give each book a unique spot on the library shelves.

  2. If the first letter and number combination is the same, then shelve alphabetically by the next letter and in decimal order by the following number. Ex  - B3.C3 1990 comes before B3.D4 1990
