I found this site from another blogger. You can make these cards by filling in the form on the site, then you are given an image you can save to your computer to insert into posts, etc.
I wasn't sure what I was doing, but this is the result. If you fill in something where it says "scribble" you get the handwriting on it too.
I thought this was great because I have so many memories of when libraries actually used these. I hope some of you agree with me that it was much better in those days. So much easier to find something you were looking for. To make your own, go
