Understanding the Value of Old Encyclopedias
The hard truth about old encyclopedias is that most sets from the mid-to-late 20th century have very limited monetary value. With the rise of the internet and digital information sources, printed encyclopedias have become largely obsolete for practical use. As one Reddit commenter noted, “While there are a few exceptions, encyclopedia sets have virtually no value. No used bookstore will buy them, and even thrift stores are leery of accepting them.”
However, this doesn’t mean that all encyclopedias are worthless. The value of old encyclopedias depends largely on their age, rarity, historical significance, condition, and collector interest. Some early editions and specialized sets can fetch impressive prices in the right markets.

Factors Affecting Encyclopedia Value
Age and Edition
Generally, the older the encyclopedia, the more valuable it might be. Sets from the late 18th and early 19th centuries, particularly first editions or early printings, can be quite valuable. Modern sets from the mid-20th century onward typically have minimal value unless they possess other distinguishing characteristics.
Condition
As with all collectibles, condition is paramount. Encyclopedia sets in mint or near-mint condition, with intact bindings, no missing volumes, and minimal wear, command higher prices. Sets with damaged spines, water damage, missing pages, or musty odors are typically worth very little regardless of age.
Completeness
A complete set is worth significantly more than incomplete collections. Even a single missing volume can drastically reduce value. This includes any supplementary materials, indices, yearbooks, or appendices that were originally included.
Historical Significance
Encyclopedias that mark important historical transitions or contain significant historical content may have higher value. First editions of major encyclopedia brands or sets that document important historical periods can attract collectors.
Binding and Aesthetics
Sets with leather bindings, especially those with ornate gold lettering or decorative elements, may have value based on their aesthetic qualities alone. Some buyers purchase old encyclopedias solely for decorative purposes, particularly those with uniform, attractive bindings.
Encyclopedia Value Assessment Checklist

- Set is complete with all volumes and supplementary materials
- Published before 1900
- First edition or early printing
- Leather-bound with decorative elements

Most Valuable Encyclopedia Editions
Early Encyclopædia Britannica Editions
The earliest editions of Encyclopædia Britannica, particularly the first through third editions (published 1768-1797), are among the most valuable encyclopedia sets. Complete sets in good condition can fetch thousands of dollars at auction.
Diderot’s Encyclopédie (1751-1772)
This landmark French encyclopedia from the Enlightenment era is highly sought after by collectors and institutions. As one of the first encyclopedias to systematically collect and present human knowledge, complete original sets are rare and can be worth tens of thousands of dollars.
Specialized and Niche Encyclopedias
Encyclopedias focused on specialized subjects (art, science, geographic regions) often retain value better than general encyclopedias. For example, early editions of specialized medical encyclopedias or illustrated botanical encyclopedias can be quite valuable to collectors in those fields.
Limited Editions and Special Bindings
Some encyclopedia publishers released limited edition sets with special bindings, higher-quality materials, or commemorative features. These special editions typically have higher value than standard editions from the same period.

Collector’s Perspective
Rare books dealer Rebecca Romney has noted that encyclopedias represent an interesting paradox in collecting: “The more useful and common an item was, the less likely it is to survive in good condition, which can eventually make previously common items quite rare and valuable.” However, this principle has yet to apply to mid-century encyclopedias because they were produced in such massive quantities and are still relatively recent.
Where to Sell Old Encyclopedias
Finding buyers for old encyclopedias can be challenging, particularly for common sets from the mid-to-late 20th century. However, several options exist depending on the potential value of your collection:
For Potentially Valuable Sets (Pre-1900 or Rare Editions)
Auction Houses: Specialized book auctions are the best venue for truly rare and valuable encyclopedia sets. Houses like Christie’s, Sotheby’s, and Bonhams handle high-value literary items, while regional auction houses may be appropriate for mid-range items.
Rare Book Dealers: Dealers specializing in antiquarian books may be interested in early encyclopedia editions. Contact members of the Antiquarian Booksellers’ Association or similar organizations.
Rare Book Fairs: These events bring together collectors and dealers who appreciate historically significant books.
For Common Sets (20th Century Editions)
Online Marketplaces: Etsy, eBay, and Facebook Marketplace can be effective for selling more common sets. On Etsy, 1966 Encyclopedia Britannica sets with 23 volumes plus index and yearbooks are listed for around $179.
Local Options: Consignment shops, antique malls, or used bookstores occasionally accept encyclopedia sets if they’re in excellent condition or have decorative appeal.
Specialty Buyers: Interior designers and set decorators sometimes purchase encyclopedia sets for their aesthetic qualities rather than content.
Selling Tips
Complete Assessment: Before listing, ensure you know exactly what you have—edition, publication date, condition issues, and completeness.
Realistic Expectations: For common sets, be prepared for modest offers or consider donating if you can’t find a buyer.
Quality Photography: If selling online, photograph the entire set, individual volumes, any unique features, and any flaws.
Detailed Descriptions: Include the publication date, edition number, number of volumes, physical condition, and any interesting historical context.
Consider Shipping Costs: Encyclopedia sets are heavy and expensive to ship. Factor this into your pricing or consider local pickup options.
Marketing Angle: For decorative sets, emphasize their aesthetic qualities and potential for interior design or display rather than informational content.
Creative Uses for Old Encyclopedias
When encyclopedia sets have limited financial value but sentimental or aesthetic appeal, consider these alternative uses:
Decorative Applications
- Home Decor: Use matching sets as color-coordinated shelf fillers or to create vintage vignettes

- Commercial Decor: Cafés, bookstores, and other businesses use vintage books for ambiance
Artistic Repurposing
- Book Art: Transform volumes into sculptural book art, hollowed storage boxes, or altered books
- Page Crafts: Use pages for decoupage, collage, paper flowers, or origami
- Framed Illustrations: Many encyclopedias contain beautiful illustrations worth preserving and framing
Educational Value
- Historical Teaching Tools: Educators sometimes use old encyclopedias to demonstrate how knowledge and perspectives have evolved
- Research on Obsolete Information: Researchers studying historical perspectives find old encyclopedias valuable
- Language Preservation: Some older encyclopedias contain terminology or linguistic features of historical interest
Community Contribution
- Donation to Specialty Libraries: While public libraries generally don’t want old encyclopedias, specialty collections or historical societies might
- Film or Theater Props: Donate to local theater groups for use as period-appropriate set decorations
- Free Little Libraries: Some community book exchanges welcome decorative books
Environmental Considerations
If your encyclopedias truly have no market or repurposing value, consider recycling them responsibly. Many communities have specialized book recycling programs that ensure the paper is properly processed.

Conclusion: The Future of Encyclopedia Collecting
The market for old encyclopedias exists at interesting crossroads. While most common sets from the mid-20th century have limited monetary value today, truly antique encyclopedias from earlier periods continue to appreciate in value for their historical significance and rarity.
For collectors and dealers, the key is to focus on encyclopedias with distinguishing characteristics—whether that’s exceptional age, historical significance, or outstanding aesthetic qualities. For owners of more common sets, understanding the realistic market value helps in making informed decisions about whether to sell, donate, or repurpose these once-treasured reference works.
As information continues to digitize, the physical encyclopedia’s role continues to evolve from practical reference to historical artifact and decorative object. In time, as fewer complete sets survive, even more recent encyclopedias may eventually develop collector appeal—though likely not in our lifetime for the most common editions.
Whether your encyclopedias are worth thousands or merely have sentimental value, they represent an important chapter in the history of knowledge sharing and home education in the pre-internet era.
