• Where the original item is in a foreign langauge and a translated version is easier to search
• To spell out numbers appearing in the first five words of a title
• To express a shorter title where the original, proper title includes an author or creator's name
• For commonly used titles which differ from the official, proper title

PBCore recommends that Titles be expressed in "Natural Language" or "Human Readable/Understandable Form." Given today's sophisticated search engines and search techniques, there is less concern about expressing Titles in strict, non-intuitive syntaxes prescribed by rule-based authorities. Titles typically are not searched as part of complex semantic interpretations, but instead employ simple matches to keywords and text strings.

Consequently, PBCore encourages producers, stations, and catalogers to assign accurate, consistent Titles to items, using more of a natural language grammar. It is acceptable to:

• Use leading articles (A, An, The)
• Use upper and lower case
• Use punctuation

Titles are typically "proper" or "given" titles supplied by the resource's creator. However, in situations where no proper title is available, e.g., photographs or segments harvested from a longer work or program, a "supplied title" may be generated. A "supplied title" must be distinctive, authoritative, descriptive and assist searching databases and catalogs, leading to successful discovery and retrieval of items.
