Thanks to those who gave feedback when I last posted! I've integrated some of your suggestions in this update. As a recap, this extension will let you determine the availability of books and ebooks at the DC Public Library when you're browsing Amazon, Goodreads, or Barnes and Noble.
You can now download the extension directly from the Chrome webstore for free here: https://chrome.google.com/webstore/detail/booksfordc/plbkclaloadjhljkijjnlingopbahndg
Feedback on this add-on and the Books for DC project still appreciated: https://docs.google.com/forms/d/1O62I5sQlwZigRo8n2tCc6IVU3SSShHE_Ymzyuz2OXM0/viewform
Best,
