NOTES |
| 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. |
