OK, not really a question, but I'm excited so I felt the need for an exclamation point.
I just had a neat idea. On WorldCat, I created a public list called "I can do lookups". Then I added some genealogical and historical books I own to it. Now, I'm going to link to that list from my profile so that anyone can see what books I can do lookups in. And at some point I'll add some of the genealogy reference books at the library to this list, since I can do lookups there, too.
But wait, there's more! Now, when you look up a book that's on my list, eg. Les Richard et d'Autres, at the bottom there's a section that shows user lists with that book in them. Mine's the only list, since this isn't a common book. So anyone looking up this book on WorldCat can see that I can do lookups in it!
Neat!
