Periodicals are shelved with the other documents rather than in a separate collection. The Sudocs numbers are also listed in the periodical printout on the documents index tables. The documents collection shelves have signs on each end which tell you the Sudocs numbers of the documents shelved there. Follow the signs and find the Sudocs number of your periodical. The newest issues of a number of document periodicals are on the documents magazine racks.
Older issues are in the collection.
Almost all periodicals in the documents collection may be checked out of the library. Those with orange labels on the cover check out for one week, the others for one month. Check them out at the circulation desk on the main floor.
