At ALA Midwinter in San Antonio in Jan. 2000 a separate task force was struck to draft an appendix listing major and minor changes, and we recommend that the charge of this task force, when officially formed, also take into account the recommendations of this current report. 3 Form a group to test and experiment with the creation of records for expressions. The operative words are test and experiment . The focus of the group should not be on the theoretical and philosophical reasonings for creating records based on expressions, but rather on the practicalities and results of doing so. The following definitions are from IFLA's Functional Requirements for Bibliographic Records .
Expression encompasses, for example, the specific words, sentences, paragraphs, etc.
The boundaries of the entity expression are defined, however, so as to exclude aspects of physical form, such as typeface and page layout, that are not integral to the intellectual or artistic realization of the work as such. Strictly speaking, any change in intellectual or artistic content constitutes a change in expression . Thus, if a text is revised or modified, the resulting expression is considered to be a new expression , no matter how minor the modification may be. The entity defined as manifestation encompasses a wide range of materials, including manuscripts, books, periodicals, maps, posters, sound recordings, films, video recordings, CD-ROMs, multimedia kits, etc. As an entity, manifestation represents all the physical objects that bear the same characteristics, in respect to both intellectual content and physical form.
