Even though I’m sure there were just as many women using pocket notebooks as men throughout history, this post from theartofmanliness.com uncovers some very interesting tidbits of notebook history.
Have upon your study table, always accessible, a good-sized substantially bound blank book. Whenever a germinant thought comes seize your pen and write it down. Such thoughts will come out of your special course of literary reading, out of your cursory scanning of current fiction, even out of the five-minute glance given to the morning paper, out of nowhere and from anywhere. Thought-compelling suggestions entirely foreign to the sermon on which you are just now engaged will frequently send you to your treasure book, and without any damage to present preparation you will scribble down a page of matter that will set you on fire at some future day just when you are in need of inspiration and help. Have also a special vest-pocket notebook and let nothing escape you. – The Methodist Review, 1907
