+# Paper notebook usage
+
+![One of my numerous stack of notebooks](/assets/notebook_52041203272_5070f094ae_w.jpg)
+
+Paper notebook sounds like an old fashioned and outdated practice in these of days of technologies. I used for years paper notebook to support me in my work and creative process. 
+Over the years, I kept my old paper notebooks for archiving purpose but also to see what's the evolution of my practices. This page is a summary of what I discovered and learned from
+the process. This page will be regularly updated with my failures and successes in notes taking.
+
+My paper notebook process is strongly linked with my electronic note (I use [nb](https://github.com/xwmx/nb) and did used [Joplin](https://github.com/laurent22/joplin) previously[^2]).
+
+Why I used a mixed model of paper and electronic notes-taking? It's mainly due to the pros versus the cons of the paper notebooks.
+
+The pros are 
+
+- being rock-solid,
+- no need of electricity or paper to use it,
+- accessible whenever you like,
+- something to hold in your hand (**like having in your hand, your project** and makes it real).
+
+The cons are
+
+- easy to lost and it's difficult to make backups,
+- the difficulty of indexing and searching in a paper notebooks. Searching for a single word in your electronic notes is fast, accurate and precise.
+
+My creative process is usually very comparable to the pattern described as [WikiStacking in communitywiki.org](https://communitywiki.org/wiki/WikiStacking). Before starting a project (can be a software project, an art project or even a business project), collecting and stacking information is a regular activity. A paper notebook is a simple and easy tool for doing so. I usually by stacking set of ideas, informations or concept into a free flow of writing. You can see an example below for writing this *noteboook usage* page, the initial stack of ideas. 
+
+![Sample page 1/2 from my paper notebook about this original page](/assets/notebook_IMG_7758.jpg) 
+
+This example is extracted from my notebook **2022-L-STACK-003**[^1] (it's a [Leuchtturm1917](https://www.leuchtturm1917.de/) A6 pocket - dotted notebook). These notes were written carelessly in a crowded train wagon. You can see the original derivation of the first notes by reading this page. That's exactly the great aspect of a notebook, it's a starter to turn your ideas into a reality. As you can see, I use dotted page because it gives me freedom to write where I like but I can still use it if I need to write a diagram and follow some rulers. Starting to write is the most important step. Then your project is starting in some reality because of its existence in a notebook.
+
+![Sample page 2/2 from my paper notebook about this original page](/assets/notebook_IMG_7759.jpg)
+
+As you can see, I have some codes of the top right of the page. The `e` value within a Pi is used as a reminder to me that I need to transpose these notes into an electronic version. I have very simple code for the TODO notes, like partially done or fully done. 
+
+## Parameters for a notebook
+
+If I want to acquire a paper notebook, I usually look at the following parameters. It also depends of what will be the use of the notebook. My main uses are the following:
+
+- Stacking ideas (writing ideas for the initial discovery of project),
+- Final notes (writing more complete ideas which will be used for reference later on),
+- Art sketching/support (related to my artist work).
+
+### Size
+
+My two favorite size for notebooks are
+
+- A6 - 105mm x 148mm
+- A5 - 145mm x 210mm
+
+The A6 size is perfect for wandering use as it fits in a pocket. The A5 size is more suitable for office or meeting use. 
+
+There is also the B7 (88mm x 125mm) which is a bit smaller than A6 and the size of a passport. I find it a bit too small for day-to-day use.
+
+### Paper quality
+
+There is huge variation between the paper quality for the different paper-based notebooks. It doesn't depend of the brand alone but also the model or the usage of the notebook. Usually sketching notebooks are with a higher gsm (grams per square meter) where a traditional note-taking notebook would be around 80 gsm.
+
+The paper quality is also important if you want to avoid the "ghost" on the next page when writing. Usually good quality notebook limits such "ghost" effect but it's not rare to see low quality notebooks having this effect. Then it's becoming nearly impossible to use your notebook pages double-sided.
+
+Concerning the color of the pages, not all notebook are using white paper but sometime a kind of yellowish paper. I personally like clear white paper especially for sketching and drawing. But it can be a matter of taste.
+
+#### Stone paper
+
+There are many type of papers used by notebook but the majority are make of real paper. But there are some exception like the "[stone paper](https://en.wikipedia.org/wiki/Stone_paper)" which are made of mineral and HDPE. Those papers are super solid and useful under extreme conditions such as seen in laboratories or extreme outside environment. Not really my cup of tea as these often lack some classical paper properties required for fast ink drying. I usually avoid such paper when buying a notebook.
+
+### Page type
+
+There are many page types in paper notebook. Page types includes:
+
+- Ruled,
+- square grid,
+- plain,
+- dotted.
+
+My preference goes for *dotted* (I mean lightly dotted) as it's a kind of plain paper with the ability to keep some structure when required. I use *plain* for my art sketching support.
+
+#### Special type project management
+
+There are many companies having creative page type from project management to-do list to more classical diary style. I tried some but it's difficult to escape the page format when needed. If I need special type page, I tend to print custom pages (like for TODO lists) or use a post-it inside the notebook itself.
+
+### Binding
+
+The binding of the notebook sounds like a non-critical element but it's the most critical one. I remember buying low-cost notebook where after 4 weeks of usage, you are loosing pages in your bag. Avoid the only glue-based binding, it's usually a source of issue. Usually it's mixed with loop stitches (or sometime combined with perfect bound or tape bound) to make the notebook more solid.
+
+There are also notebook with spiral. I avoid the notebook with a spiral binding like the plague because these tend to broke in my bag or mess-up with other stuff.
+
+Another important aspect, a paper notebook needs sometime to lie flat properly. And it highly depends of the binding. Test it and see if you can easily open it and keep it without too much pressure.
+
+### Strap/Elastic
+
+Having an elastic is a must for a paper notebook. There are different reasons such as:
+
+- If you put small papers, notes or tickets, these are kept inside the notebook.
+- Another reason, if you have bag with a lot of things inside, you might crush the pages of the notebook. When it's closed with an elastic, such issue is less prone to happen.
+
+Good paper notebook tend to have a strap/elastic but some brands don't have one. If you have a notebook you really like and don't have an elastic. There are elastic including sometime paper clip bookmark which can do the job. Natural rubber band (more resilient than plastic ones) can also do the job and can be very useful as these are very extensible.
+
+### Cover
+
+Soft cover and hard cover is usually a matter of taste. I tend to prefer a hard cover for A5/A4 size but for pocket-size notebook, I prefer soft cover as it's more flexible when you have to squeeze it in a small bag or pocket.
+
+### Addons
+
+#### bookmarks
+
+One bookmark is the minimum, nowadays paper have one or more bookmark. Having two is the most convenient setup for me. As you can label a start set of pages and the current one. If your notebook is missing a bookmark, hard bookmark can also do the job.
+
+### Brands
+
+#### Leuchttrum 1917
+
+Paper quality (80 gsm) + good texture
+
+#### Moleskine
+
+#### Bindewerk 
+
+Sketchbook 160g (blank) are great
+
+Notebook

+My [original Moleskine hack page](http://www.foo.be/cgi-bin/wiki.pl/MoleskineHack) from 2009.
+
+#### Numbering pages
+
+Many brands now include page numbering but it's not always the case. Then you must not forget to number the pages if you use your notebook as a stack of information and you need an index to find back easily a topic.
+
+#### Name and number your notebook

+# Disclaimer
+
+I didn't receive any free paper notebook to do this page. I'm not a bloody influencer and I did this to give ideas to other using paper notebooks. Nevertheless if you are a producer of paper notebooks, I won't be against to receive some samples for testing. But be careful, I might be negative in reviews or provide feedback to buy from another manufacturer.
