Lately, we’ve crossed a major milestone, surpassing 31 million unique ISBNs in our database. This impressive achievement is a testament to ISBNdb’s ongoing commitment to providing the most comprehensive and accurate ISBN information available.

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.

We’ve significantly reworked our crawlers to gather more data and made them faster. In addition, we’ve increased the number of data sources to expand our database more efficiently. Consequently, not only will we add many more new books, but any missing data for existing books will be added to the database faster as well.
