BiblioChart
BiblioChart Independent Bestsellers
BiblioChart is a monthly independent bestseller list built to spotlight the books readers are actually buying from independent authors and small publishers.
A Bestseller List for the Independent Book Community
Every month, participating authors and publishers submit eligible sales totals for their titles. BiblioChart compiles those submissions into a public Top 20 list published on Proxima Emporium and shared through email and social media.
Subscriber participation helps offset the cost of maintaining, reviewing, publishing, and promoting the chart. Rankings are based on reported eligible sales, not advertising spend or paid placement.
For Authors
Submit your monthly book sales and give your title a chance to appear on an independent bestseller list designed for discoverability and promotion.
For Small Publishers
Track and submit sales for your catalog while helping build a recurring chart that gives independent books more visibility.
For Readers
Discover books gaining traction beyond the traditional bestseller ecosystem, including independent fiction, nonfiction, poetry, and genre titles.

Why BiblioChart?
Independent authors often generate meaningful book sales without ever appearing on traditional bestseller lists. BiblioChart creates a recurring, visible, and shareable way to recognize those books while helping readers discover titles outside the usual channels.
The goal is simple: build a monthly snapshot of independent book activity and give authors a new promotional milestone worth sharing.

Reporting Period
BiblioChart rankings are based on sales that occurred during the designated monthly reporting period. In most cases, this means sales from the first day through the last day of the previous calendar month.
Sales Month
The month in which the eligible sales occurred.
Submission Window
The period when members submit sales data for the previous month.
Publication Date
The date when the BiblioChart Top 20 is published on Proxima Emporium.
Required Submission Information
Each monthly submission should include enough information to identify the book, sales period, sales total, and reporting party.
- Book title
- Author name
- Publisher or imprint, if applicable
- ISBN, ASIN, or other retailer identifier
- Primary format being reported
- Total eligible units sold during the reporting period

Supporting Documentation
BiblioChart may request supporting documentation when needed to confirm eligibility, clarify reported sales, or resolve inconsistencies.

- Order export files
When Documentation May Be Requested

How Rankings Are Determined
BiblioChart rankings are determined by eligible reported units sold during the chart period. The books with the highest eligible reported sales totals are ranked in descending order.
If two or more titles report the same number of eligible sales, BiblioChart may use submission timestamp, documentation completeness, or other internal review standards to determine final ordering.
Advertising & Rankings
Advertising purchases, promotional services, banner placements, newsletter features, or other paid promotional opportunities within Proxima Emporium do not affect BiblioChart rankings.
BiblioChart rankings cannot be purchased. Paid promotion and chart eligibility are separate programs.
Corrections & Updates
If an error is discovered after submission, members should contact BiblioChart as soon as possible. Corrections may be accepted before the monthly chart is finalized.
Once a chart has been published, BiblioChart may issue corrections at its discretion but is not required to republish a ranking due to late, incomplete, or corrected submissions.
Member Responsibility
By submitting monthly sales data, the member certifies that the information is accurate to the best of their knowledge and that reported sales meet the standards described on this page.
Repeated inaccurate, inflated, misleading, or unverifiable submissions may result in loss of eligibility or removal from the BiblioChart program.
