Thank you for this excellent script. I was able to do my own first tweak and added my local library site to the list.

GRPL: {
name: "Grand Rapids Library",
link: "http://lakenet.llcoop.org/search/a?searchtype=t&searcharg={search}&SORT=D&searchscope=1&submit.x=14&submit.y=20&submit=Submit",
icon: "http://www.grpl.org/favicon.ico",
scanURL: "lakenet.llcoop.org",
},

Thanks again!
