You can also search the corresponding online database for entries added since the issue date of the compact disc, if online capability is available on your system. Terms entered on the Subject Words lines are searched in the Basic Index, which is derived from title words, subject words, and single words from other data elements. If multiple terms are entered on a single line, the logical AND operation will be performed by default. The logical AND operation is always performed between lines.
Some databases have different search categories.
