Click on Dewey services.
It can be accessed directly from the Connexion client by going to Tools>Launch WebDewey. It will then open directly at the WebDewey search screen in your default browser using your default OCLC authorization.
It works with Internet Express and Mozilla Firefox. IE is needed if you want to use the work area.
WebDewey opens at the Search box. You may enter one term or several.
616.959 in Dewey numbers-obvious search to check numbers found on OCLC
records-both for what the number means and for currency if it indicates 21 or earlier edition (Can
be entered with or without segmentation marks.)
Results screen at one point in the schedule shows:
Work area (IE only)
Shaded title box with class number, caption, and several buttons with links, including a link to our Voyager OPAC.
Notes and Terms link to the bottom of this screen.
Dewey hierarchy shows the numbers above the one you've looking up. To get related numbers on the same level, go up one level to Sexually transmitted diseases, Zoonoses.
Notes, which include any Add instructions.
Terms from the Dewey Relative Index and LCSH. Explanations of the three types of LCSH (click to see):
EM Editorially mapped by a classifier
PPM People, Places & Things, an OCLC print list of the LC Subject headings and Dewey numbers for the most popular topics
SM Statistical mapping of Dewey numbers on records in WorldCat
For Add instructions click through and it opens in a new window (IE) or a new tab (Mozilla Firefox).
We can add User Notes if we want to record a particular local usage or preference. They follow all the editorial notes. One that I added was about our local literature numbers.
The number of hits for search terms varies depending on which search you choose.
Photography in Relative Index (61 results)
Photography in LCSH (Editorially mapped) (15 results)
Photography in Relative Index or LCSH. Return to the search screen to combine searches (92 results)
Photography in All Dewey (80 results)
With some of these result sets, it can get tedious paging down to find the aspect you want, especially if it's toward the end of the schedule, 700s to 900s. You can see that LCSH (Editorially Mapped) is the most precise search, especially if you have a subject heading from a record, and All Dewey or a combination of searches works well if it's a very precise term or you're not sure of the term.
Example of use of the Work Area
Copy the number for Zoonoses and then a subdivision from the Add table. We could also add a geographic subdivision to that (though we probably wouldn't). Then it can be copied to a Voyager MFHD.
If you want to add something that you know is from a table, for example -0l from Table 1, you can search it in Dewey numbers by putting t1-before it.
A good way to find locations to add after -09 is to search in the Relative Index. The table references come before the schedule numbers.
The other main way to find numbers in WebDewey is to browse.
To do this, click on Browse. This allows one of the following searches on one term:
Dewey Numbers (with Captions)
Relative Index (KWIC)
LCSH (Editorially Mapped)
Note the KWIC (Key Word in Context) searches.
From Search or Browse, click through to the schedules at a particular number.
You can then do another quick Search or Browse on one term directly from the schedule. If you want to combine terms, however, you should return to the Search page.
Photography in Relative Index
Photography in Relative Index (KWIC)
Photography in LCSH (this can be useful if you don't remember the exact wording of the subject heading)
Colombia-History in LCSH (can be a useful way to get to the period subdivisions quickly)
770 in Dewey Numbers (with Captions)
Because the captions are included, you may also use words in this search but the results can be inexplicable:
Photographs in Dewey Numbers
LCSH Editorially Mapped means that someone has decided that this Dewey number goes with this particular subject heading. Usually yields smaller set of results.
Reading comprehension Search in All fields
Results are from table 4 as well as schedule. At T4-86 the words are in a note
Reading comprehension Search in LCSH
Fewer results-two in 372
Reading disability in LCSH
Which call number you use depends on whether the stress is on clinicians (616.855) or teachers (371 or 372). The book is a test for diagnosis, so we can add -075 according to the instructions in the schedule to use an add table.
Maple in Relative index (Maple trees gives no results)

Social conflict in All fields
