Digitization projects, public libraries, and broader access to literary materials help create copyright markets. Together, these access infrastructures build the literate public and long‑run demand that copyright ultimately depends on.
In 2016, the Delhi High Court was asked whether photocopied course packs for university students unlawfully undercut the market for academic books. The Court’s decision ruled in favor of the course packs, in part by finding that “by producing more citizens with greater literacy skills and earning potential, in the long run, improved education expands the market for copyrighted materials.”[1] This note surveys the evidence that supports the court’s finding.[2] First, studies show that digitization projects, such as Google Books, which make works easily searchable and partially readable online, can increase, rather than depress, print sales. Second, scholarship shows that access through public libraries and free lending only modestly displaces the bestseller margin with little measurable impact for the long tail of titles. Third, by examining scholarly culture in households along with policy syntheses on school libraries, studies explain how early and repeated access to books during formative years builds durable reading habits, longer educational trajectories, and the kinds of literate text‑using adults on whom creative and academic markets ultimately depend. Taken together, these strands do not prove the Delhi High Court’s dictum in a single econometric stroke, but they offer a coherent anecdotal scaffolding for its core intuition that investments in access and education can expand, rather than extinguish, the market for copyrighted works.
Google Books Digitization and Print Book Sales
The Google Books case offers a natural experiment on whether free digital access necessarily cannibalizes print sales. When the project was launched, publishers argued that searchable, partially readable copies online would undermine the market for physical books.[3] They litigated this claim to the U.S. Supreme Court, which ultimately held that Google’s secondary use was protected by fair use.[4] In 2023, two economists revisited the publishers’ anxieties by exploiting the way Harvard’s Widener Library contributed its pre‑1923, out‑of‑copyright holdings to Google Books. Volumes were scanned in shelf order between 2005 and 2009, rather than by demand or popularity, so the timing of digitization for any particular title was effectively arbitrary. The authors track 37,743 of these titles and compare their print sales in the two years before the main scanning period (2003–04) with sales in the two years after (2010–11), asking whether books that happened to be digitized followed a different path from otherwise similar books that were not. Because digitized titles are fully text‑searchable and viewable online, they function as discovery tools. Readers can find them via keyword search, skim a few pages, and then decide whether to purchase a physical copy.[5]
Their results show that digitization can expand, rather than erode, the market for many books. Roughly 40% of digitized titles see an increase in print sales over the study period, compared with fewer than 20% of titles that were never scanned, and on average being searchable and readable on Google Books is associated with an increase in physical sales of up to about 8%. The effect is most pronounced for relatively obscure works in the long tail, not for the handful of titles that already sell well. The authors also find a spillover. Once readers discover a digitized work by a given author, they become more likely to buy that author’s other, non‑digitized titles. Taken together, the findings suggest that large‑scale digitization and free online discovery can serve as an access infrastructure that helps surface neglected works and stimulates demand across an author’s catalogue, complicating simple claims that free digital access must be bad for print markets.
Effect of free access through libraries on print sales
In 2022, a study of the Japanese public library systems showed that free access through public libraries modestly displaces sales only for bestsellers and has a minimal detectable effect for most other books. Kanazawa and Kawaguchi analyze Japan’s dense public library network by building a title‑municipality‑month panel that links, for each book, how many copies local libraries hold to how many copies nearby bookstores sell over time. Their empirical strategy controls for fixed differences across titles and municipalities, for the typical life‑cycle of sales after publication, and for municipality‑month shocks, so that the remaining effect can be interpreted as the impact of additional library copies on local retail demand.
Within this framework, they find that library holdings substitute for purchases at the very top of the demand distribution, but not elsewhere.[6] For the most popular sixth of titles, each additional library copy reduces monthly bookstore sales in the municipality by about 0.24 copies, and for bestsellers the estimated displacement rises to roughly 0.52 copies per month. By contrast, for the majority of less popular titles, the estimated effects are statistically indistinguishable from zero. Adding library copies does not measurably change local sales. Across robustness checks, this pattern holds, suggesting that in a highly literate, library‑rich country like Japan, public libraries have a small amount of demand for already successful books but do not “destroy” the long tail of the market. As an access infrastructure, then, they provide broad reading opportunities while leaving most of the book market intact.
How Early Access to Books Builds Lasting Reading Habits
Household scholarly culture and school‑library studies show that early, repeated access to books helps build the readers on whom later creative and academic markets depend. In their cross‑national work on 27 countries and later across 31 societies, Evans, Kelley, Sikora, and Treiman find that growing up in a book‑rich home is strongly associated with more years of schooling and higher occupational status, even after controlling for parents’ education, class, and occupation.[7] On average, children from homes with a substantial number of books complete about three more years of education than those from bookless homes, and the size of this effect is comparable to having university‑educated rather than unschooled parents. A follow‑up study shows that home library size also predicts entry into higher‑status, more knowledge‑intensive jobs, mostly because it channels children into longer educational trajectories in the first place.
Policy syntheses on school libraries point to a parallel institutional story. When schools provide rich collections and professional librarians, students’ literacy outcomes systematically improve. The World Literacy Foundation draws together evidence that access to books through homes, schools, and public libraries supports literacy development and stable reading habits, especially for disadvantaged children.[8] Building on more than 50 years of research, Tania Otero Martinez’s report for the Center for American Progress shows that well‑resourced school libraries staffed by certified librarians are associated with higher reading and math scores, better graduation rates, and particularly strong gains for students in high‑poverty and linguistically diverse districts. The loss of librarians, by contrast, tends to be followed by stagnating or declining performance.[9]
Taken together, these household and school‑level findings suggest that access infrastructures in childhood and adolescence- home book collections, public and school libraries- do not just raise test scores in the short term, they cultivate durable reading habits and educational pathways that can later generate sustained demand for, and use of, creative and scholarly works.
Conclusion
Ultimately, these studies do not deliver a single econometric proof, but together they trace a consistent pattern: access infrastructures like digitization and libraries are at least compatible with, and often generative of, markets for books and academic materials. In that sense, the Delhi High Court’s intuition, that investing in education and literacy can expand the audience for copyright, rests on firmer empirical scaffolding than its brief dictum might suggest.
Summary of studies employed and findings
| Study | Access Mechanism & Design | Key Findings |
|---|---|---|
| Google Books (Reimers & Nagaraj) | Large‑scale digitization of 37,743 pre‑1923 Widener Library titles; scanned in shelf order (quasi‑random timing); compare print sales pre‑ (2003–04) and post‑digitization (2010–11). | Digitized titles are more likely to see sales increases; digitization is associated with up to ~8% higher print sales, especially for obscure works, with spillovers to non‑digitized titles by the same author.
Shows that free online discovery can stimulate, rather than uniformly cannibalise, book markets. |
| Japan public libraries (Kanazawa & Kawaguchi) | Free lending via public libraries; title‑municipality‑month panel linking library holdings to local bookstore sales, with rich fixed effects and controls. | Each extra library copy modestly displaces monthly sales (≈0.24–0.52 copies) only for top‑selling titles; for the majority of books, displacement is statistically insignificant.
Indicates that free access slightly reduces bestseller demand but leaves most of the market intact. |
| Scholarly culture in the home (Evans et. al.) | Early access via home “scholarly culture,” proxied by the size of the home book collection across 27–31 countries.
Growing up in a book‑rich home predicts roughly three extra years of schooling and higher occupational status, net of parental education and class. Effects are robust across regimes and especially strong for disadvantaged children. |
Suggests that early access to books builds human capital and readerly dispositions that underpin later demand for textual and academic goods. |
| Occupational Outcomes (Evans et. al.) | Long‑run effects of home libraries on job attainment in 31 societies.
Home library size has a substantial positive effect on occupational status, mostly mediated by higher educational attainment, with a smaller residual effect even after controlling for education. |
Reinforces the claim that book‑rich environments generate knowledge-intensive careers and ongoing engagement with written materials. |
| Access & literacy (World Literacy Foundation) | Synthesised evidence on access to books via homes, schools, and public libraries, especially for disadvantaged children.
Concludes that ready access to books supports literacy development, academic achievement, and durable reading habits. |
Frames book access infrastructures as central to creating lifelong readers, which provides a qualitative bridge from education policy to future markets for reading materials. |
| School libraries (CAP / Otero Martinez) | Institutional access through well‑resourced school libraries staffed by certified librarians.
Across ~50 years of studies, finds consistent associations between strong school libraries and higher reading and math scores, better graduation rates, and improved outcomes for students in high‑poverty and linguistically diverse districts. |
Shows that institutional access infrastructures systematically improve literacy, expanding the pool of future users of creative and academic works. |

- One strand of cultural economics argues that rising levels of education and economic development foster the production and consumption of high art. As societies become wealthier and more educated, they are better able to purchase artworks, which in turn makes it easier for artists to secure a basic livelihood and frees more of their time for creating work that is valued for its intrinsic, rather than purely financial, rewards.
