hi

could you recommend me what is the best reader can i use with iLiad||
like ipdf and other readers.

usually i use PDF format. because i convert files to PDF to read them on iLiad.
what is the best format to use with iLiad.

is there any format or readers that include indexing for chapters to easy search inside files.

if the pdf already has hyperlinked chapters in an index

i believe they are already hyper linked on pc but when i try on iliad doesn't work.
