Do I have the right Dewey Number?
Double-check to see if the number you have assigned an in with general convention.
 * In real life you would see if the item fits in the location of similar items in your current collection.
 * Go to OCLC Classify (see below), type in the subject of the item in the subject box. Select a title that is close to the one you are classifying. When you click on the title of the item, it will tell you the percentage of books cataloged with a particular Dewey number.
 * Use the //Sears// database in JCKL or a copy cataloging source for verification of the Dewey number you have selected.

Assigning Dewey Numbers
> most common use
 * The easiest way to assign Dewey numbers is to borrow a copy of Abridged Dewey (the most current version is edition 15 (2012). Another way is to borrow a Sears List of Subject Headings (the most recent being the 20th edition (2010). If neither of those options is easily available to you, and you don’t have access to the //Sears// database at JCKL, then the Web sites below offer other ways to find ways to assign a Dewey number **
 * **// OCLC Classify //** - []
 * **// OCLC Classify //** - []
 * Click on the tab "Title/Author" or "Subject"
 * Type in a main topic of the item being cataloged
 * Click on "search"
 * Find a title in the result list similar to the item being cataloged
 * Click on the title link
 * Will give you the most common Dewey number assigned to this title
 * Will give you the most common subject headings assigned to this title

Understanding Dewey 590 Animals
(Blog post by Barbara Paciotti) **I recently received an email from a colleague asking me if I could explain how the animal section of the Dewey Decimal System is organized. Here is my response. Hope it helps some of you, dear readers.**

**The 500s are my forte, having been a secondary science teacher before becoming a librarian. Since Dewey classifies according to discipline (field of study), Biology is 570-590;Dewey numbers are based on that discipline’s scientific nomenclature: Kingdom>Phylum>Class>Order>Family>Genus>Species (broadest to most specific) & by the increasing complexity of living things with 570 being the cellular & internal level, followed by 580 Plant Kingdom & 590 Animal Kingdom.** [|**Continue Reading**]

Understanding Dewey 900s Countries
(Blog post by Barbara Paciotti) **In a recent email I was also asked about an explanation for the way the countries in 950-990 are organized. Here is my response & hope it will be helpful to others.** **Regarding 900s History & Geography, both 910 Geography & Travel as well as 940-999 History have separate Dewey numbers for all continents & countries based on DDC Table 2. Your school library may have some geographic country books in the 910s along with travel books, but school libraries typically simplify their collections by putting geographical country books into the 940-990 History numbers, probably because most school-oriented country books are for social studies research & include both geography & history. What makes 940-999 country numbers confusing is that we think of History in terms of political timelines, but Dewey numbers in Table 2 are assigned geographically rather than politically–a location’s political affiliation may change but it’s place on the earth doesn’t. It does have a very Anglocentric historical aspect, however, beginning with the continent of Europe at 940, then moving roughly circular from north to south & east to west with 950 Asia, 960 Africa, 970 North America, 980 South America, 990 Australia & Oceania.** [|**Continue Reading**]
