Locating Periodicals signs throughout the building tell you on which floor to find call number ranges. A floor plan on each floor shows the general area where the call number is located. Periodicals are intershelved with books. There is no separate periodicals room. If you cannot find the issue you want, check the sorting shelves, the tables in the area, photocopying tables, and, finally, the Circulation Desk.
Some periodicals are also available in microform.
If the title of the periodical you need does not come up in the online catalog, ask at the Reference Desk for assistance. Reference librarians will be happy to help you with using indexes or locating periodicals.
