The old system was self-explanatory. With this new system you need a tutor to figure it out. Not user-friendly!!!
Thanks for the feedback! This new catalog overlay was intended to give people more options, but we definitely don't want to make your life more difficult! The previous interface is still available; if you prefer to do a classic search of the catalog (which is similar to the old search) just look toward the bottom of the web page and under Library Links click on the link for Classic Catalog.
I hope that helps. If you are having trouble with anything in particular, please let us know and we will be happy to walk you through it or offer you other options.
