My niece who lives in Ramat Bet Shemesh told me that her shul reads all haftarot from a klaf (parchment).
It has been a while since I have seen a shul use a scroll for haftarah. The last shul I attended had separate scrolls for each book of the prophets.
I know that Ramba"m in Hilchot Sifrei Torah 7:14 states that one may write the entire Tanac"h in a single scroll and that this has been done before.
Can one write more than one book of "Nevi'im* on a single scroll? Or is Rambam's statement applicable to only all of tanac"h but not just a part of it?
