How to read a call number
Items in Tisch Library are shelved in order of their Library of Congress call number.
Items are first arranged on the shelves in alphabetical order by letter:
| A | B | F | H | J | JA | K | KF | KFM | Q | QA | T | U | Z |
Within each letter combination, they are arranged by the number:
| QA 76 |
QA 273 |
QA 273.25 |
QA 273.4 |
QA 279 |
QA 279.2 |
Then, items are arranged by the alpha-numeric segment, which is read as a decimal number.
Thus, .M4 is read as M.40 and follows .M388 (read as M.388) on the shelf:
| QA 279 .H83 |
QA 279 .M388 |
QA 279 .M4 |
QA 279 .M44 |
QA 279 .M5 |
QA 279 .S5 |
You can use the maps of the collections--Floor Plans: Level G | Level One | Level Two--at Tisch Library to find the general area of the library where your call number will be located.
