Evidently Treasured Thoughts is a fairly popular name, but here you go. http://cocatalog.loc.gov/cgi-bin/Pwebrecon.cgi?Search_Arg=Treasured+th oughts+&Search_Code=TALL&PID=eyYF_WKhZEytK6X5r_NWvlDtj2M&SEQ=200807170 62944&CNT=25&HIST=1
Just scroll down to the collection that fits you to obtain copyright number. I found one for Alice in 2003.
To found out what is listed you will need to call (202) 707-6850 to ask them what is listed under your copyright. I think to research it costs $150/hr. but I am not 100% sure. They can tell you if there is a way to view the list online, but I don't know of any.
Sorry this wasn't much help. Susu
