Why don limits work on some searches?
Limits do not work on author, subject, or call number searches from the Basic Search screen, nor do they work on course reserve searches because they are set up as either browse or authority searches. The best compromise is to use the Advanced Search and specify either Subject or Author Name in the ‘Find words in:’ box. You can either set the limits before searching or perform the search and apply limits afterwards with the ‘Post Limits” button. This technically is not a subject or author search, but a keyword search on the subject or author fields. Also, searching by journal title and limiting by Type does not work and has been reported as a software bug.
