There are several ways to search for book attention in the Altmetric Explorer. You can search by unique identifier, author, or by book DOI prefix. 

Searching by a single unique identifier

Explorer now lets you search by ISBN. Paste your ISBN in the search bar and you will be given the option to search by ISBN. You can also search for a book's PMID, DOI, or any other identifier this way. 

Searching by multiple identifiers

To search for multiple book identifiers you will need to use the Advanced Search.  Click "Advanced Search" below the search bar. Once the pop-up opens, click on "Search by scholarly identifiers". Then paste in all the identifiers you'd like to search with. 

Once you've added your identifiers, click Save. This will bring you back to the Advanced Search. From there click "Search".

Search by DOI prefix

Often publishers assign DOIs to their books along with ISBN/eISBN. You can then search by the publisher's unique DOI prefix in the "Advanced Search". 

For example, if you are searching for Routledge Handbooks, you can use their DOI prefix 10.4324 and select Books and Chapters in "Type of output".

Searching by publisher

You can also search for books by publisher. In "Advanced Search" type in a publisher name in the box that says "Publisher Name". To make sure you only get Book and Chapter content select "Books" and "Book Chapters" and then click "Search".
