Depending on the set, extras can include pens and elastic pen loops, adhesive note/index tabs, a ruler sheet, and inner storage pockets.
They range from single-subject notebooks to multi-subject formats; common options include 1-subject, 2-subject, 3-subject, and 5-subject configurations.
Common pocket styles include simple inner pockets for loose notes, reinforced or "tough" pockets designed to resist tearing, and some notebooks include an extra double-sided storage pocket for documents or receipts.
Look for perforated pages, bleed-resistant paper, and acid-free stock. Reinforced pockets and water-resistant covers also help protect pages from tearing and moisture.
Smaller pocket notebooks typically measure around 4.25 x 5.5 in or 5 x 7 in, with others near 6 x 9.5 in; some descriptions explicitly note that the smallest sizes fit in a purse or pocket.
