Yes, you can search online and it will show you whether it has such a book either at Ludington, one of the other five libraries in Lower Merion Township, or even any other library in all of Montgomery County. I have found sometimes that if the book I am looking for is older, maybe not so currently popular, that I will find it at Norristown Library. But you can find every location in Montgomery County for the book (and whether it's in or checked out) by searching on the website.
The library has an online catalog you can use to check and reserve books
