Frequency Frequency is the interval at which a publisher distributes a serial publication. Frequency as a limiter for serials Use frequency in combination with a publisher name to find all the publications from a publisher that are monthly, yearly, weekly, and so forth. Language keywords as limiters Use language to limit your search to records for items in a specific language. Languages available You must use 3-character codes or spell out the language you want to search. A list of available codes and languages is in OCLC-MARC Codes Lists.
Most records are for English language items, followed by Spanish, French, German.
Other languages that appear often are Russian, Portuguese, Chinese, and Japanese. Always combine English language searches Because English is the prevailing language of WorldCat, a search for eng or english retrieves more records than the system can display. Always combine English with other keywords. Publisher Publishers are the persons or companies who are responsible for placing the book on the market. A publisher and printer may be the same person or entity, although in modern publishing this is not usually the case.
