What kind of notebook? Paper or Leather Binding?
Has it been exposed to the elements? Hidden in a nook for a few decades?
Do you need the paper to be supple, brittle, or crinkled?
There are many ways of doing this but you need to be more specific as to the level of aging and what you're aging, including the kind of paper you are using; regular notebook paper such as most of us are used to don't age as fast as the stuff used prior to the 1950s; pulpy paper likewise ages differently, frequently become dried out and brittle.
You could use Tea to stain the pages of the book but that technique frequently results in very stiff and wrinkled pages. There is a spray available through Artist Supply stores, I don't have the name off hand, but it was developed for the sake of antiquing paper & card stock. I think it retails for around $12.00 a for 8 ounces and depending on how aged & stressed you want your paper, you may want to dilute it. . . for a more even coloring I'd use an airbrush and not the pump it comes with (it sputters and makes things blotchy).
Take a look at items made of the materials you plan on using that are the approximate age you plan on going with. Fact of the matter is, if it is something 5-10 years old, you really needn't do much of anything but make the book look well worn... a few weeks in the hip pocket as you go through your daily routine should prove sufficient.
