Dewey Table

Computer science, internet 004.678 Titles about the internet or WWW go here if they contain a substantial amount of technical material, i.e., how the specific hardware components or software applications of a network operate. Use 025.042 for books on the internet that have some computer science material but also address other topics, such as how to search the web. Prefer a number in the 300s if the item-in-hand has very little technical information and focuses instead on the socio-economic or political implications of web technologies.
Controversial knowledge 001.9 Use for interdisciplinary works on parapsychology, occultism, and other questionable topics/phenomena. Also consider 130, another number covering topics that cannot be disproved or brought into the realm of certain and verifiable knowledge. Dewey guidance on distinguishing between the two numbers: Prefer 001.9 for topics not closely linked to human affairs (UFOs, Sasquatch); prefer 130 for titles focused on the human mind and its capabilities.
Collections of quotations, jokes, interviews, etc. 08X Prefer 808.882 for more literary collections. Use the 08Xs only for familiar/popular material.
Manuscripts and rare books 09X Use for items that provide the history, description, or critical appraisal of rare printed material. Consider the 700s for works on the artistic aspects of illuminated manuscripts.
Media/journalism/publishing — sports 070.4497 Items here should be by or about journalists who primarily cover sports. Use 796.XXXX for titles that don’t focus on media coverage of a league, team, or athlete. Use BIO if the person covered is extremely well known.
Media/journalism/publishing — political commentary 070.92 Try to keep (a) memoirs by political reporters here or, if very famous, in BIO (b) political culture books in the 300s and (c) historical analyses/documentary works in the 900s.
Media/journalism/publishing — photojournalism 070.49 Use for books about visual reporting. Put collections of photojournalism (items with more pictures than narrative text) in the 700s.
