SINGAPORE - More Singapore publishers are converting their titles into e-books, something long practised by academic and educational presses here. It is now increasingly common for local trade publishers working in fiction, non-fiction and poetry to do so even as the challenge of making a profit in the format remains for smaller players.

This month, Straits Times Press launched 20 e-book titles on Amazon Kindle, ranging from financial journalist Lorna Tan's bestselling collection Retire Smart (2018) to Janice Tay's fantasy novel The Memory Eaters (2017). Two more titles are planned for May.
