Alice Sneary has posted a useful item–new info for some people and a good reminder for others–on the WorldCat Blog for info pros, advanced searchers, or those who want to be a power searcher.
The post is about a number pieces of search syntax (specifically called index labels) that are available when you want to do some power/expert searching with WorldCat. You can enter the two letter codes plus the search terms into any search box and you’ll off and running.
Only some of these labels are accessible using pull-down menus on the advanced search page BUT using the codes where and when needed can save time and a lot of effort once you learn a few of the basic labels (i.e. ti=title).
Conducting an expert search and using these labels places a lot of control in the searchers hands.
Here are a few WorldCat labels that Alice included in the blog post:
bc: BC year
dd: Dewey Decimal Classification number
ge: genre, like a novel
isbn: the ten-digit number for a book
issn: the eight-digit number for a magazine or journal
mt: material type, like a DVD
pb: publisher, like Ballantine
yr: year of publication
These labels are only a few of the ones available. This page lists them all with examples of how they’re used.
