It includes the title, statement of responsibility, edition, material specific details, publication information, physical description, series, notes, and standard numbers.";

Access points are the retrieval points in the library catalog where patrons should be able to look up the item.\r\n\r\n  In other words, the rules in AACR2R are used to answer questions such as: For this book, should there be entries in the catalog for more than one author or more than one title? Should the title of the series be noted? How should the author's name be written? Is this a 'title main entry' item (no author)?";

Use of an approved list is important for consistency, to ensure that all items on a particular subject are found under the same heading and therefore in the same place in the catalog.\r\n\r\nFor instance, the subject headings list indicates that all books about cats should be assigned the subject CATS. Using this authorized heading eliminates the possibility of listing some books under CATS and others under FELINES. Even if a book is called ALL About Felines, the subject headings will be listed in one place in the catalog for the patron to find. The patron does not have to imagine all the possible synonyms for the word he is looking for.";

The second part of the call number usually represents the author's name, facilitating this subarrangement.";
