For those who are Bookr-impaired may want to consider NIMS’ PSP EBOOK Reader. Hacked PSP not required. NIMS’ EBOOK Reader v1.0 is simply javascript; it can be used on any PSP running any firmware, so long as that firmware postdates the NetFront Web Browser. Also included are tools for converting PDFs to HTML. Read README.txt. It’s got you covered.
