Google Summer of Code Contributors Improve Open Library’s Patron Experience

This year, as part of Google Summer of Code (GSoC), the Internet Archive is collaborating with two outstanding contributors to make it easier for patrons to find relevant books on Open Library.

Tanishq Sangwan, a 19-year-old from Gurugram, India, and Chisom Nnamani of Lagos, Nigeria, are two of 1,141 software developers from around the world who have been selected through GSoC to hone their engineering capabilities with open-source organizations.

“The Internet Archive’s focus for 2026 is: tools for participation. Participation must be earned by building an experience patrons want to return to.” said Mek, program lead for Open Library. “The work that both Chisom and Tanishq are doing is central to creating a more reliable Open Library experience, where readers can repeatedly discover, access, and enjoy books.”

Tanishq Sangwan

Sangwan, who just completed his second year of college studying artificial intelligence, is focusing on the journey of patrons who join Open Library and use it once, but do not return. His objective is to understand where patrons encounter barriers and identify opportunities to create a more useful, lasting experience.

Sangwan comes into the project with two years of experience from ZNotes, an educational organization that provides free notes and videos from students around the world.

“I built this passion and got this amazing feeling when my work was making an impact on people and they were receiving some value,” he said. “Now, Google Summer of Code is a wonderful opportunity to connect with open-source organizations and Open Library where its work directly impacts people’s lives.”

“This year’s collaboration is important because lots of patrons discover Open Library, but too often don’t always find the books they want,” Mek said.

The work begins when a patron lands on a book that is unavailable for reading. Soon, instead of reaching a dead end, patrons will be presented with nearby books on the same shelf that are available now.

When patrons find a relevant, available book, a simpler registration process will help them get started with fewer steps and return to the book they found. Furthermore, Sangwan is helping patrons connect with new book recommendations on an ongoing basis by introducing an activity feed to the account page.

“I like to hear about the patron psychology, how they’re interacting with the platform, and what’s going in their mind from the first moment to the very last,” he said. “We’ll be researching and conducting interviews with lost patrons so we can connect this bridge between patrons and the millions of books in our catalog.”

Chisom Nnamani

Nnamani, who already has certifications in Data Analytics and Data Engineering, just completed her sophomore year pursuing a second degree in Computer Science. At Open Library, Nnamani is leading a major cleanup effort to add structured tag data to books so they can be searched by genre and subgenre. Her work is paving the way for the addition of a wide variety of new searchable tags, including: moods, fiction and non-fiction, content warnings, and literary formats, such as memoirs, biographies, and more. By cleaning up messy data and enabling better genre and subject browsing, Chisom is helping remove barriers preventing patrons from discovering books they love.

“Today, many of our subject pages feel computer generated and can’t compare to the beautiful, curated experiences you find at small book stores,” says Mek. “The work Chisom is leading to map the messy subject tags we have to clear genres and subgenres will help us offer patrons a more useful and satisfying browsing experience.”

“I really care about books being accessible to people,” Nnamani said. “In Nigeria, we have limited access to physical libraries, so Open Library is something that matters. It gives everyone the opportunity to come and read any kind of book and gain insights.”

“This project is inspiring to me,” Nnamani said. “I like to work on projects where I can connect the data and infrastructure in ways that contribute to the organization’s goals. I enjoy helping to solve complex problems at the intersection of systems and data.”

Open Library Fellows work remotely, but meet regularly online with Internet Archive staff and mentors. At the end of the summer, each contributor will publish a blog post explaining their technical journey and experience gained.

Since 2005, Google’s Summer of Code has supported more than 23,000 students from 123 countries with stipends to receive mentorship and contribute 48 million lines of code to over 1,000 open source organizations worldwide.
