Periodicals held in the Library of Congress collections are found in the following formats:
A title could be held at the Library of Congress in one format or multiple formats, depending on the date of publication. Keep in mind that not every periodical has been digitized and the Library of Congress does not hold a copy of every title published. To determine whether the Library has a particular periodical and how to access it, one may consult several sources. Most periodicals held by the Library of Congress can be found in the Library of Congress Online Catalog (physical materials) and the E-Resources Catalog (digital). Below is information on how to search those catalogs and how to identify what reading room the periodical can be accessed. Be aware that most e-resources are limited to on-site access only. If you are unable to find what you need, please feel free to ask us, as reference staff also use printed resources and catalogs that are not found online.
Periodicals are listed in the Library of Congress Online Catalog. To locate a periodical, search under the title (such as Sports Illustrated) or under the name of the issuing agency (for example, American Mathematical Society). If you do not find the periodicals you are seeking, be sure to ask a reference librarian for assistance.
