How the Dead Sea Scrolls were Written

The book "The Dead Sea Scrolls: A New Translation" (HarperCollins Publishers, 1st Ed.) describes the practical construction of a scroll from the Dead Sea collection, on page 8:

What, exactly, are the Dead Sea Scrolls? The object themselves are documents written with a carbon-based ink usually on animal skins, although some are inscribed on papyrus. The scrolls were written right to left using no punctuation except for an occasional paragraph indentation--no periods, commas, quotation marks, or any of the other reader helps to which we are so accustomed. Indeed, in some cases there are not even spaces between words: the letters simply run together in a continuous stream. The codex, the early form of the book with pages bound on one side, had not yet been invented, so the "pages," or columns, were written consecutively on the scroll. To read them one slowly unrolled the scroll, and then, to be polite, rewrapped it, like rewinding a modern videotape. Not a few of the scrolls testify that the ancients failed to rewind as often as we do. The scrolls are written in several languages and half a dozen scripts, and though all are religious texts, within that category their contents are amazingly varied.
