The drawback is that long pages take longer to download. Your customers may not want to wait for your latest novel. Shorter pages do not take as long to download, but if you think people will want to download or print out 35 different pages, think again. If there is a natural break in your subject matter, display it on a separate page. Limit the page length to about three scroll downs.
People seem to be happier with that number.
Limit the page size to 30k - 50k total byte size. You won't know how big your pages have become until they are produced, but your web developer will know. Include all the graphic images in that total byte size limit. The power of the Web is its ability to link to any other page in the world. However, be very careful.
