So true, bihira din ako bumili ng local books. Anyway there are many Filipiniana books in public libraries. For sure especially inside the National Library. Hehe.
I used to be a voracious reader until I started working. 😆 But mostly I read English books nga. Konti lng tlga local like kay F. Sionil Jose pero English p rin. 😅 I think only Bob Ong became popular in the vernacular.
Anyway aside from what you mentioned, the NBDB also has a lot of initiatives to encourage new and old writers. This is great for everyone because more Filipino literature will be and are being produced.
Gusto ko rin puntahan yung DOST library! Haha. For sure maraming science books doon. As for major book fairs napakaraming tao masyado kaya di rin ako nagpupunta. Maubos pa budget ko wag n lng haha.
