UC Library Search includes books, articles and more.
Are there filters in the left sidebar that will help you narrow your search results? Click on the category ("language" "geography") to view the options.
When you encounter any kind of source, consider:
1. keyword search; phrase search, limiting to scholarly articles
(keywords) . "yellow wallpaper"
"to room nineteen"
quotes keep two or more words together
limit to scholarly articles (checkbox on the left) (note: very current topics may have few scholarly articles as of yet)
2. wildcard
(keywords) . madness domestic*
child* = child childs children childish childhood...
3. narrowing a search with additional terms
"yellow wallpaper" gilman
madness domestic* litera*
madness domestic* novel*
4. alternative terms; use broad subject categories
women hysteria* litera*
still a lot of irrelevant results...
go to the filters in the left column, click on subject, click on "show more" and check off "criticism" and any other category that seems literary (don't bother with book reviews though)
