This study was to conducted to define how metatags are used by Ohio public library webmasters and to determine the de facto standard for metatag usage. The 106 Ohio public library World Wide Web sites accessible through the Ohio Public Libraries Information Network (OPLIN) were evaluated using a statistical analysis of the HTLM code and content of the metatags. The number of library web pages that did or did not use metatags was counted, and the pages with metatags were divided into four groups--generated, standard, mixed, and free. Frequencies of the following types of meta fields were examined: (1) content fields, including title, subject, description, source, language, relation, and coverage; (2) intellectual property fields, including author, publisher, other contributor, and rights management; and (3) instantiation fields, including date, resource type, format, and resource identifier. Results are presented in table and percentage chart forms. Findings indicated that 45.3% of the libraries used metatags which were automatically generated by software tools for web page design, and 41.5% of the libraries did not use metatags at all. Frequency of metatag fields included were: content (59%), intellectual property (27%), and instantiation (14%). Results indicated that the de facto standard includes keywords, description, author, and date fields. (DLS)
