Do pdfs count as books?

My father, Morrie and his sister Florence both wrote memoirs about their lives in Austro-Galicia and their early years in Chicago. I digitized both manuscripts, scanned relevant pictures, and created 2 pdfs. Along with my Charnabook, all are available in the menu on the left under Family Stories. I never printed out the two memoirs and created actual books. Although I have a list of 15 possible topics to pursue, with one urgently calling to me, I’ve decided to make those two books first. Should be simple, no?

Aside from the novelty structures I enjoy, there are two basic ways to bind a book: folded signatures or single page. The pdfs are single page; after all, they aren’t usually bound. Single page binding, like Japanese stab bindings, can be beautiful but they don’t open flat. I’ve used this binding several times, and I’m never entirely happy.

Folded signatures allow for several types of bindings, most of which will open flat. However, they are half a page. The largest signature book I’ve done is 8.5 inches by 7 inches, half of a legal size (8.5″ x 14″) sheet. Until recently that was the largest sheet I could print. I now have a larger printer that takes a 13″ x 19″ sheet.

My first task is to decide on my page size, then decide on the binding. The pdfs are 8.5″ x 11″ with several pictures covering an entire page. Half of an 11″ X17″ sheet gives me four 8.5″ x 11″ pages, and all sheets have to be considered as four pages. Morrie’s memoir has 114 pages, Aunt Flo’s has 45 pages. So Morrie’s book would be expanded to 116 or 120 pages; Aunt Flo’s to 48 pages. Some of that is easy; a blank page at the front and back and maybe on the reverse of the title page. Next question is how many pages or sheets in a signature? Placement of the content depends on the number of pages in each signature. For me, keeping the pages straight is the most difficult part of the whole job.
