Look up Library Congress Call Numbers: What They Are and How to Use Them



When you look up a book in the Library's online catalog, the call number listed for a book is how you will find it on the shelf (shorter books may have their call number in the bottom left hand corner of the cover). The call numbers are arranged alpha-numerically.

College and university libraries use the Library of Congress Classification System to organize their books, DVDs, and more. The benefit of having a standard classification system is that no matter what academic library you go to, your research subject should be in the same call number range.


You may start with different information, depending upon whether you got the number by looking at a description or display page or by copying down the number when displaying the image. Some general rules of thumb for searching digital id. numbers are:


If you see: A digital file name that ends with two sets of numbers, seemingly not numerically related (or you simply try searching the final set of numbers, dropping the letters as instructed above, and get no result) You type: The second to the last set of numbers (or, more precisely, the second to the last set of numbers, and the letters appearing after"/pnp/")


In some cases, a general size range can be gleaned from a filing designation given in the CALL NUMBER field. Letter designations that appear at the end of many Prints & Photographs Division call numbers for individual prints, photographs, and drawings (posters are an exception) indicate the size of the container in which the item is housed.


Sample call numbers that include container designations: ADE 11 - Marie, no. 2 (C size) PGA - Schulz, F.G.--Stuttgarter Bilderbogen (B size) FP - XX - S354, no. 3 (D size)


Most print books in the University of Michigan libraries are organized by Library of Congress (LC) call number as a method to group like subjects together on library book shelves. Each book has a unique identification number (or shelf address); this number is found on the spine of books (or sometimes on the front cover) and in the library's catalog records.


Sometimes the library location is also indicated on the book label above the call number (for example GRAD, for the Hatcher Library, or BUHR, for the Buhr Shelving Facility, or FINE, for the Fine Arts Library).


When the top two lines are identical, look to the third line. Books are first ordered alphabetically; books with the same letter in the third line are then arranged by decimal number (not whole number.) The following call numbers are in correct order:


When the top three lines are identical, look to the fourth line. If it contains a letter followed by numbers, items are organized by letter and, within each letter, by decimal number. (Note that this works just like the line above it, treating the numbers as a decimal even though there is no visible decimal point.) The following call numbers are in correct order:


Some call numbers will include lines at the bottom to describe the volume, issue or part of the larger publication. These are shelved in alphabetical or numerical order, whichever is used. The following example is in correct order:


Those call numbers are also sorted line by line, like LC call numbers. The first line is sorted by whole number, and the second line is sorted by letter and then by decimal number. They are then sorted by letter, if applicable, and finally by edition (which is indicated by publication date). The following Dewey numbers are in the correct order:


When searching the library catalog you may encounter records for other items like DVDs, maps, microforms, dissertations, and manuscripts, which will likely use other forms of call numbers or unique shelf addresses. For example, a DVD located in the Askwith Media Library might have a call number like this: VIDEO-D 80644-D - H70667. A map in our collections might use a call number such as: NEW MEXICO TO 1939. An historical newspaper on microfilm might have a call number like this: FILM X979. Manuscript collections housed in the Special Collections Research Center might display a call number such as ALTMOV-3233.


Prints acquired after about 1970 may have a call number beginning with PR 13, reflecting the year in which the material was acquired. Advance arrangements are needed to view items with call numbers beginning with PR 13 (see Looking at Prints in the Reading Room--PR 13 (unprocessed) prints, below).


Currently, this provides the most comprehensive access to prints in the Fine Print Filing series. The catalog is arranged by the century in which the artist flourished, and thereunder by artist name (see details about how the call numbers are expressed in Introduction above). An additional section of the catalog provides access to selected artists and works organized by country.


Researchers who are able to visit on site may request to view prints by submitting a call slip in the reading room. We generally request that for prints already digitized at high resolution, researchers first look at the highest resolution file (tiff file) to gain as much visual information as possible, before requesting to view an original, as retrieving and refiling fragile prints puts added wear and tear on them. Please contact us in advance if you want to see more than 15 prints on a single day.


LIBRARYThis represents the MIT library in which the title can be found. In this instance, the Dewey Library.*Please note that there are 5 libraries in the MIT Libraries System, in addition to the Libraries Storage Annex. Be sure to make a note of the library for the title found before you visit the library to look for the item.


First look at the top line. In the Library of Congress system, the first line will be 1-3 letters long. Items are shelved in alphabetical order by these letters. Use the chart above to determine where the item is shelved in the library.


Next, the third part consists of a single letter and then a sequence of numbers. Items are shelved alphabetically and then numerically based on this line. This line is always read as if it were preceded by a decimal.


The first line of a Dewey Decimal Call number will be a whole number, potentially with a decimal component. Items are shelved numerically. Use the chart above to determine where the item is shelved in the library.


Libraries use classification systems to organize the books on the shelves. A classification system uses letters and/or numbers (call numbers) to arrange the books so that books on the same topic are together. This arrangement results in "serendipitous browsing:" you find one book in the catalog, go to the shelf, and, an even better book is sitting right next to it.


Most books in the SPU Library are organized by Library of Congress (LC) call number as a method to group like subjects together on library book shelves. Each book has a unique identification number (or shelf address); this number is found on the spine of books (or sometimes on the front cover) and in the library's catalog records.


These unique shelf location numbers allow the books to be organized alphabetically by Library of Congress (LC) subject letters and numbers, grouping like subjects together for easier browsing. (See complete list of LC subject classification categories for details.)
