As titled, I have recently bought a couple of books across platforms that are ACSM-encrypted, and would like to see if there is any E-Readers that supports drawing annotations.
I have tried several ebook readers but was unable to find one. I would prefer drawing graphs and mathematical formulas along as I read, than simply a text note....
If not, any recommended note taking applications for such purpose? (as I am unable to, or actually very troublesome, to convert ACSM book to pdfs) Any recommendations would help.
Thanks in advance!!!
