Rare Book Hub Introduces Rare Book Batch Valuation Service

Rare Book Hub is launching the beta version of its Rare Book Batch Valuation service this month and will be officially accepting member submitted lists of material beginning October 15th. Batch Valuation is a new service that enables you to quickly search for auction lot matches to your entire book collection in our database of over 12 million records. Instead of searching titles one at a time, Batch Valuation enables you to submit a list of hundreds, thousands, even tens of thousands at once for automated searches.

Next, for each matching lot for each title found, we update past sales prices to current value using an inflation index based entirely on book auction sales prices (not a standard formula like CPI). From those, we provide an Excel spreadsheet showing both the average and mean inflation adjusted value of all lots for each title you submit. We also provide a list of all the underlying records on another sheet of the Excel file to make cataloging, sorting, and filtering easier. Additionally, a probability of reappearance at auction (measured in years) is included based on how frequently the title has come up for sale in the past.

Finally, we sum up all of the inflation adjusted values, both average and mean, to give you estimates of the value of your entire collection. A practical means of estimating the value of a large collection based on actual sales prices has never before been possible.

Who Is This For?

This service will assist collectors in estimating the value of their books and anticipating expected prices when they sell, booksellers to determine inventory value and reasonable selling and buying prices, auction houses in valuing the collections offered to them and setting estimated prices and preparing descriptions for sales, and libraries for valuing their large collections, estimating deaccession values, determining appropriate insurance amounts, and deciding whether to accept collections offered.

Free Trial for Annual Subscribers

Since Batch Valuation is still in Beta formation, we are making free test runs available to paid annual subscribers to the Rare Book Transaction History at no cost. Up to 3 runs of up to 500 titles may be submitted without charge now through December 31, 2022. Naturally, we welcome your feedback as we work to perfect the presentation of results and the algorithms that power the estimates to best serve your needs.

How to submit your lists:

Create a simple spreadsheet with the following columns:

1. Number

2. Author’s last name

3. Title [up to 7 words]

4. Date printed

5. Place Published

Example, with required headers:

InternalCatalogID	Author	Title	YearPrinted	PlacePrinted
