Lately, we have made two major improvements to our book database, enabling users to access even more comprehensive and accurate information about books.

The first upgrade is a new data point-related ISBNs. This feature allows users to reference other ISBN editions and formats related to a particular book, providing a more complete picture of the book’s publication history.

The other enhancement is the updated publish date field, which now has 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 are also excited to let you know that the number of ISBNs in our database has exceeded 28 million!

These new features are part of ISBNdb’s ongoing commitment to providing the most up-to-date and accurate information about books. With these enhancements, users can now easily find books published within a certain time frame and access a more comprehensive overview of a book’s publication history. Whether you’re a book lover, researcher, or industry professional, ISBNdb is your go-to resource for ISBN information.
