Project News

We are happy to announce that we now allow users to use credit cards for their ISBNdb subscriptions and a paypal account is no longer required.  

We are excited to announce discounted Academic and Non Profit plans for students, educational institutions, and non profits.  For only $5 USD monthly, the academic and non profit communities can get access to the full ISBNdb database.  To enroll in an Academic plan, click on the ISBN database link in the header, scroll to the bottom and sign up.  Please note the Academic plan includes all the same features as the standard Basic plan, but with a lower daily call limit. 

As a subscriber, not only do you get access to the data API but when logged in to ISBNdb.com you can search and get all data for any book we have directly on the website.

We just deployed higher API request limits for Premium and Pro plans.   All Basic Plans will continue to have a 1 request per second limit, Premium Plans will have a 3 request per second limit, and Pro Plans will have a 5 request per second limit.  The existing daily call limits continue to apply to any 24 hour period.  For details on how to implement higher per second requests for Premium and Pro plans please see our API documentation.   Thank you for your continued support.

The database continues to grow, increasing to over 24 million unique isbns and growing rapidly.   Our revamped crawlers are adding new isbns and adding new data points to existing books at a fast clip.

API 1.0 is no longer live, please ensure your code is formatted correctly according to the API 2.0 documentation available at https://isbndb.com/apidocs/v2.  All existing API keys will work so there is no need to make any other changes.  If you were subscribed to an older plan, your billing rate will be grandfathered in unless you cancel or switch plans.

Effective April 23 2020, we will no longer offer support for API 1.0.  You can continue to use the old API if you have an old plan, but we won't be offering any updates or support so if there are any technical issues you should upgrade to API 2.0.  You can switch plans in your dashboard at any time. 

We updated our crawlers to gather more data faster, and expanded our data sources.   Not only will we add new books at a faster rate, but any missing data for existing books will be added to the database faster as well.  

Our crawlers have been hard at work and we are now up to 23 million unique ISBNs in our database.
