Stop wondering if your library has it. Book Bridge connects your Goodreads shelves to your local Libby libraries, so you can see at a glance which books you can borrow right now, which have a holds queue, and which aren't in yet. WANT TO READ, READING, READ, DID NOT FINISH All four of your Goodreads shelves, in one place. Switch between them with a tap. Every book shows its cover, author, and the date you added, started, or finished it. Missing a date? Add it from the book's card. AVAILABILITY FOR EVERY LIBRARY YOU BELONG TO Add each of your Libby libraries. Book Bridge checks eBook and audiobook availability at every one of them, so you know not just whether a title is available but where. Green means borrow now, yellow means a holds queue, gray means not available yet. One tap opens the book in Libby. TWO-WAY GOODREADS SYNC Finished a book? Mark it as read in Book Bridge and it moves on your Goodreads shelf too. Start one and mark it as currently reading, or set one aside as did not finish. Dates you add are saved to Goodreads, and changes you make on Goodreads show up in Book Bridge on the next sync. SORT, FILTER, AND SEARCH Sort your Want to Read list by availability, title, author, or date added. Filter to just the books that are available or on hold. Search any shelf by title or author. FREE AND PRO Book Bridge is free to use with one library, and it checks availability for the 3 newest books on your Want to Read list.

Verdict
The clearest difference is review sentiment: Book Bridge Library Search at 100% against BookBub's 54%. Book Bridge Library Search also leads on rating (5.0 vs 4.7) and iOS requirement (16.4 vs 26.0). BookBub's advantage is in-app purchases (none vs 1) and ratings volume (961 vs 9). On price, update cadence, ads and monetization model there is nothing between them.
