If you have a call number, you can search that number to locate the Franklin record for that book.

You may also browse a specific topic by searching a class number. For example, searching the Library of Congress classification on business ethics produces a list of books from all the Penn Libraries (except Biddle), including High Density Storage, that have call numbers beginning with the same letter(s) and numbers. This allows you to browse the combined stacks of all the libraries at once.

Leave a space before a date designation in LC and Dewey call numbers.

Use a period in LC call numbers if one appears in the first part of the call number.

It is not necessary to type a space or a period directly before the first cutter (g43). All three of the following produce the same result.

If a period is present anywhere else in the call number, it must be included in the search.

In an LC call number, if more than one letter/number combination appears after the class number (Z695.1 below), called a "double cutter", you must leave a space before the second letter.

Other kinds of call numbers are used for microforms (microfilm, microfiche, microprint).

Some rare & manuscript materials use unique call numbers.

For dissertations and theses, use a period and a space after "diss."

Call numbers for sound recordings consist of the record label name or abbreviation and the LP or CD number. Spacing and punctuation both matter.

Call numbers for partially cataloged items, i.e., those with no publication date or with the "temporary catalog record" note, are not searchable. Please ask for assistance.
