2. National Standards for K-12 CatalogsThe three principles in cataloging are to show the patron the materials, help the patron choose the materials, and to help the patron locate the materials. To keep cataloging uniform throughout the U.S. the Anglo-American Cataloging Rules 2nd edition (AACR2) was created. It is also a standard practice to use the Abridged Dewey Decimal Classification and Relative Index and the Library of Congress Subject Headings with children’s headings for the nonfiction materials. MARC bibliographic records are the digital version of the bibliographic record of each item and there is a catalog of Marc records for items located and accessible via the Library of Congress Website. When cataloging books the librarian may and probably will use a combination of the resources I mentioned earlier in this paragraph. One good resource for cataloging is the LOC authority records that keep the authority of author’s name and title of materials/books. This past year working as an intern at our middle school library and I re-cataloged all the 920’s in the library’s collection. The intention behind this re-cataloging and classifying is that the 920’s were being underutilized and if they were shelved in other areas in non-fiction then they would be accessible to students and teachers. I used the Dewy Decimal Classification book to find and the proper call number for each book. I then used the cataloging module of the Alexandria automation system to change the call number in the record and of each book. <br /> Description, Classification, and Access to Library Materials<br /> Librarians can use the tasks of describing and classifying library materials to allow for greater access by both teachers and students. Many titles may fit several subjects and therefore a librarian who knows the students and their searching habits at the school can describe or classify titles so that they will be more readily accessible and seen. A good idea is to create a Series sections for students do not always know the authors but they know the titles. For example the 39 Clues are written by different authors but need to be shelved together because they are so popular with the students. I know of several librarians who have created a graphic novel section in their library. Graphic novels and Manga have been becoming increasingly popular and in libraries with high circulation rates of materials of these genres or libraries who want to promote these genres is would a good practice to classify these items in their own separate sections. I have read on the TLA listserv that several librarians have classified and shelved there fiction novels by genre. The librarians who commented on this method of classifying stated that they were able to better promote the books by using eye-catching photos and graphics for each genre and placing the graphics right above the shelves. They also commented that they were able to promote the reading of certain genres by also placing above the shelves along with the graphic of each genre a catchy title such as ‘blood and gore’ for the ‘horror’ section and ‘laugh till you cry’ for the ‘humor’ genre. <br />
