Google Books has a wonderful search tool that lets you find specific strings in books and they used to have that ability in the "My Library" feature. I loved being able to search my personal library for information where I didn't remember exactly the references where I had found it. (See my June 15,2009 post here.)
It looks completely different now where the books are strung out pictorially in some useless categories such as favorites, read, to be read, etc. instead of just listed with publishing information like they used to. I know what my books look like, I don't need a picture of the jacket.
I can still search the entire Google library and then sift through the hundreds of results for the ones that I've flagged as being in my library. However, there is no way for me to narrow my search choices down to the ones I have, instead of the millions that Google has catalogued.
Why did they have to go and "fix" something that wasn't broken?
