You can use the same searches you used effectively in
the catalog (both subject and keyword), and get a lot more results! WorldCat is
the closest thing there is to a universal library catalog. It includes the
holdings of thousands of libraries worldwide.
Use the limiters: for example, “not juvenile” and “not fiction.”
Subscription WorldCat defaults to put the most popular materials on top. Free WorldCat defaults to put the most relevant materials on top.
Because you are searching a much larger universe of material, you may want to search for your terms only in the title.
If a very small number of libraries (think single digits) hold the
item, we may have trouble getting it through Interlibrary Loan.
