I happened upon some websites that have tools that might be handy for making zines and little books. I haven't used any of these yet, but I think they could have potential!
BookletCreator is an online tool which allows you upload a pdf file and have it reformatted into an 8 page booklet.
PocketMod is an online tool which helps you make a little booklet which looks an awful lot like a Teeny Tiny style mini book.
PagePacker is a freeware program for Mac which is like the PocketMod with a little more functionality, like being able to incorporate pdf files as pages in your tiny book.
I have always just done cut-and-paste for my zines/books and am mostly happy with that, but it might be fun to experiment with these tools--and other tools, for that matter, if you read this post and want to share other stuff you've seen online along this line!
