Dear teabag woman. I am sure it is possible to purchase book wrapping paper or a card from a book shop. Or draw a grid on paper and colour it in, or even match boxes with lines drawn to represent books. Or even dolls house books and book shelves. Hope this helps a bit.
I used to make mini books by getting a few sheets of paper, cutting it out to double a book size with a sheet of coloured blotting paper or wrapping paper on the bottom, staple it through at the middle, fold it over in half and you have a little book with a cover - the staple is in the spine if the book obviously.
Do a long strip of paper into a concertina, and then stick one side and cut the other. Go to the copy shop with some books and tell them to reduce the side of the covers, and stick them on the first page and the back cover on the last page. Or use washi tape. Done.
If you can get some balsa wood of the appropriate thickness (stacks of it on A****n) you can cut rectangles with your Stanley knife. Sandpaper a curve onto the spine, and wrap sandpaper round a pencil to make the opposite edge rounded inwards. I used thin leather from an old glove for a cover. (Very bad photo, sorry.)
they have losts of good things to make out of paper for dolls' houses and you can find book covers with labels there.
You can make the inside of the book out of anything from thin card to thin wood, depending on what tools you like using. Cut a rectangle of a suitable size for the book cover and the book-shelf(!) and glue it inside the cover.
If you google free printable dolls' house books and magazines you can find other sites than the one I have suggested.
Cut strips of paper the length of an A4 sheet and say, 2cms high, fold each into a zig-zag - each (double) fold will be one page so don't make the folds too wide. Glue inside the folds on one side of the zig-zag only and you will have lots of "pages". Glue them inside a "cover" of whatever you fancy. Wrapping paper, fabric, leather etc. Easy. 👍
If you cut small pieces from a thick cardboard box they'll look like books when they're placed end on. You could felt-tip the 'spines' to colour them if you don't want to cover them.
My 10 year old gd is very keen to make miniature rooms in shoe boxes, particularly a library. Can anyone suggest something simple that I can wrap paper/felt round to represent books? My mind has gone blank. Your help will be greatly appreciated, being fumble fingered crafting has never been my thing but my gd loves it.
