This session will cover …• The advantages and pitfalls of using

WebDewey 2.0• General approach• How to log on• The basic structure of WebDewey 2.0

records• Introduction to browse, search, and tables• Introduction to built numbers

Advantages of WebDeweya) You can keyword search all of Dewey, and

use Boolean searchingb) You can access notes and related numbers,

by clicking on linksc) WebDewey includes terms and built numbers

which are not found in the print versiond) Some Dewey numbers have Library of

Congress subject headings linkede) WebDewey is completely up-to-date, but the

print version is not, and is getting more and more out of date

Less appealing featuresa) Number building can be more difficult,

especially for complicated numbers such as literature numbers

b) Because Dewey was designed for print, it’s not fully suited to an online interface. It’s important to start with a good understanding of the print version

WebDewey is not Google!• Approach WebDewey in the way you

would the print version, by browsing down through the summaries of the main classes and checking the relative index.

• You still need to determine the subject and discipline of a work, and think in exactly the same way as when using the print version of Dewey.

Once you have logged in, by default you are using the 23rd edition of Dewey, which has orange buttons.

Click on “Home” to see the ten main classes

Clicking on “000” displays the summary for the ten classes below

Clicking on “090” displays the ten classes below. This approach enables you to find a number by

drilling down through the hierarchies

Browse option

• Useful to check a Dewey number that may already be on the record

• Allows you to drill down from a general to a more specific number

On the left you enter your browse terms, and on the right select the index that you wish to browse

Drilling down from a general to a more specific number

Search option

• Useful if you have very specific keywords, that may not be in the relative index

• Finding the Dewey number corresponding to a Library of Congress subject heading

• Find a more detailed Dewey number from a base number

Tables

Introduction to built numbers

• Identified by a small “B” in your search results

• You need look at how the number has been constructed, and its scope.

• Sometimes the scope of built numbers is much broader than is immediately obvious in WebDewey

The instructions tell you to add “7” from the table “Add as instructed under 362-363”.

This takes you to 363.1257 – but covers everything from using seatbelts, to school traffic patrols
