“The ‘death’ of Flow [two years ago] helped me to solidify my idea,” Lam says. “A bookstore is a name for a format. The name isn’t actually important but it allows people to associate it with a concept, a physical space to buy and sell books. If you were to ask anyone who’s opened a bookstore, even Robert Wu of Eslite, a bookstore might not be about selling books.

“Eslite wasn’t designed just to sell books, it was conceived to bring culture into a shop format, and to allow the greater public to access this culture.”

Similarly, Flow-brary is built on the idea of a library, but is in reality a crowd loaning social project that Lam compares to Wikipedia. “What we need is for Flow to break out of its physical space, so the idea of Flow-brary can expand each book’s reach and proselytise reading culture, but also retain the intimacy and mom-and-pop aspect of the bookshop,” he says.

In his mind, the shortcomings of a public lending library are its stringent deadlines. Through Flow-brary, he would allow readers to keep books as long as they wish, or until other customers request them, eliminating the need for Flow itself to store the books.

“Something as beautiful as a bookstore will have its ups and downs over the years, and we may have new ideas and additions to it, but I would like to allow my original purpose to be kept,” he says.

That purpose is to have books be so cool that they are carried like a handbag under one’s arm as a badge of honour – “much like those people who walk around holding a Starbucks cup”, Lam says.

“I simply want to play a role that in a busy city, a bookstore or a book can give you a space for escape, to allow you to become alienated from the busy world, without having to go sit by a river in Tai Po.”

While this project is ongoing – and it some ways, has already begun organically, with Lam’s practice of loaning and gifting without necessarily keeping track – the bookseller has also engaged in a bit of a social art project for nearly a decade.

Each customer who leaves with a book must have one of their acquisitions photographed in their hands. It’s Lam’s way of paying homage to each volume that flows through Flow. By now, the photos number in the thousands, and the conversations that emerge from this process are just as many, thanks to his gregarious personality and tendency to expound on the history of each book sold, from highlighting its author’s background to the edition of printing.

Initially, he photographed book buyers’ faces, too, and posted their stories on social media. But because of privacy preferences, he subsequently decided to show only their hands.

“There’s no final destination or a presentation,” he admits. “But when I started to do it without faces, it’s a different project and more meaningful. By keeping it anonymous it has less boundaries, meaning I don’t need to know who the next person giving this book a home is, but that I know the book has a home.

“This is the chain of Flow,” he says.
