Is there a trick in searching LCCNs?

On the Basic Search screen, type the index label ln: before the LCCN. Example: ln:map32-14

You may type the number either with or without the hyphen(s).

You may also search via the LCCN index from the Advanced Search screen.

Do I have to worry about initial articles and stopwords?

No. CatExpress treats title searches as a form of keyword search which uses stopwords. The most common articles in English are included in the CatExpress stopword list. They are automatically dropped before the search is done. There should be no difference if you put them in your search or leave them out. (We recommend that you drop "with" and "within" when searching.)

What are the CatExpress stopwords?
