Project News

We have refined our search algorithm to provide you with more relevant results on text queries.

Our hard-working crawlers have added one more million ISBNs to the ISBNdb database. Check our subscription options; each one comes with a free trial.

We are excited to announce the launch of our blog. On the ISBNdb Blog, you can find a monthly digest of book publishing news, insightful posts on book data, book apps, and more.

Our database has grown with another 2 million ISBNs, and we now offer over 33 million unique ISBNs. Sign up for a free trial to test our API and get full access to the website.

We now have over 31 million unique ISBNs in the database, including over 27 million cover images and up to 19 data points per book. Our crawlers continue to add books at a rapid clip, with thousands of new ISBNs and new data points for existing ISBNs added daily.

We removed the old "synopsys" and "overview" data points, and consolidated and replaced with "Synopsis".  This eliminated some redundancies and made the data cleaner.  Synopsis is now the data point that has the book description. 

We updated our search filters so you can now filter by publish date, edition, and year on both the website and through the API. 

We now have over 29 million unique ISBNs in the database, including over 12 million cover images and up to 18 data points per book.  Our crawlers continue to add books at a rapid clip, with thousands of new ISBNs and new data points for existing ISBNs added daily.

You can now query by publish date, and we have updated the publish date data field to have a standard 4 digit year for any book published after the year 1900.  For any book published prior to 1900, the data is unavailable but you can query related ISBNs for versions published after 1900.

We added a related ISBN data point so you can now reference other ISBN editions and formats that are related to your book.
