Where to start: empty the whole shelf or organize in place?
Take everything off and put it on the floor. It sounds radical, but it is the only way to see what you actually have. Organizing book by book without emptying the shelf just rearranges the clutter, it does not solve the problem. Books that no longer need the space stay right there, taking up room that could go to something you actually use.
I spent a day in an 85m² apartment in Perdizes organizing the library of a teacher who had been collecting books for fifteen years. She had six shelves in the living room plus stacks in the hallway and by the bed. She would spend ten to fifteen minutes searching for a title when she urgently needed one, and she had bought three duplicate books without realizing it.
When I suggested emptying everything out, her reaction was immediate: "there's no need, I roughly know where everything is." Forty minutes later, with the books on the floor divided into categories, she found two titles she thought she had lent out years earlier and realized the entire third shelf was books she had never opened.
With the shelves empty, the process becomes clearer. You see the total volume, clean the dust that had built up behind the books, and can decide more calmly what goes back and what leaves. Without emptying it out, the decision is always skewed by what is right in front of you. You tend to keep everything because it already looks "tidy enough."
How to organize the emptying process
Set aside an afternoon with at least three hours available. For large libraries, split the work by shelf across different days if needed. As you take out each book, make an initial split into three piles: keep, decide later, and goes. The "decide later" pile exists for genuine doubts, not as an excuse to avoid deciding anything.
- Empty one shelf at a time onto the floor
- Clean each shelf before putting anything back
- Split into three piles: keep / decide later / goes
- Process the "decide later" pile before organizing what stayed
- Do not buy any organizer before seeing the final volume
How do you decide which books stay, and which can go?
Four questions settle most decisions: do I reread or consult this often? Does it have real reference value? Do I keep it out of genuine affection? Will I read it in the next six months? If the answer is no to all four, the book goes. The real difficulty is not the logical decision, it is dealing with the emotional weight of certain titles.
Boxes on the floor are, almost always, the most honest part of a library. In a home in Moema, I organized the collection of a 58-year-old client. Four full bookcases plus two boxes on the floor that "were waiting for space" for three years since her last move. They had never been opened since arriving at the apartment.
When we opened the boxes, there were books from her 1989 college years, novels with inscriptions from people she had not seen in decades, and travel guides for destinations she had already visited. Each one had a story. The resistance to letting go of anything was far greater than with any drawer or clothing closet.
The solution was to create an honest category: keep for sentimental value, with a limit of one full shelf. Any book she wanted to keep for memory or sentiment, with no need to justify it, went on that shelf. Once the shelf filled up, something would have to leave to make room for another. The physical limit did the work that the rational argument could not.
The two boxes went to donation, one to the neighborhood's public library, another to the project Leitura para Todos SP, which picks books up at home and distributes them to public schools and NGOs in São Paulo. One entire shelf had room to spare for the first time in fifteen years. The client said it took her a day to get used to the result. After that, she never once missed the books that were gone.
The four categories that work
- Consult or reread: books you open frequently. They stay on the main shelf, within easy reach.
- Reference: technical books, manuals, dictionaries. Grouped together; they do not need to be in plain sight if used only occasionally.
- Sentimental: kept for memory, not for use. Physical limit of one shelf.
- Goes: donation, used bookstore, or public library. Books in good condition have an easy destination in São Paulo.
Which system works for you: color, author, genre, or reading status?
There is no universally best system, there is the one that matches how you actually search for a book. If you tend to think "I want a novel" before choosing, organizing by genre makes sense. If you think "I want the latest Saramago," organizing by author is more logical. Picking the prettiest system without considering your real behavior is the most common mistake after curation.
In a 65m² apartment in Pinheiros, a couple with very different reading habits shared the same bookshelf. He read science fiction. She read psychology and personal development. Each bought books without knowing what the other already had. Books were scattered across three rooms, some in the bathroom, others on the dining table, with neither of them able to say where anything was.
She wanted to organize by color because it would look nice. He wanted it by author. Neither had considered the real problem: two different search systems coexisting in the same space with no shared criteria.
We landed on a system organized by reading profile: his science fiction took up two shelves split by series; her books filled two more, split by subject area; one shared shelf for books they both wanted to read; and one to-read shelf for each of them, side by side. They stopped buying duplicate titles because, for the first time, they could actually see what they had. The look became tidier as a result of the system, not as the goal.
Comparison by reader profile
- By genre or subject: works for most people. Easy to maintain. You search by area, not by title or author.
- By author (alphabetical):ideal for people with complete collections or who always search by the writer's name. Does not work well if you mix many genres.
- By reading status (read / unread / reference): the most effective option when the to-read pile is out of control. It separates the collection from the reading queue.
- By color: visually striking, functionally limited. Works well on decorative shelves or for the sentimental shelf, not as the main system.
Your bookshelf does not need to look like a bookstore. It needs to work for your real life, and have room for the next book you are going to buy.
See home organization →What to do with the "someday I'll read it" pile
The TBR pile (to be read) needs a physical place and a limit. Books you intend to read scattered across the shelf, mixed in with ones you have already finished, create a false sense of an endless queue, and often you do not even know how many titles you actually have left to read.
Set aside a specific shelf, tray, or nook for the books you want to read in the coming months. Once that shelf fills up, stop buying. It sounds simple, and it is. The problem is that most people never make the queue visible: new books get mixed in with old ones, and the pile grows without anyone noticing the accumulated volume.
- Visible TBR shelf: pick a spot at eye level if possible. You will see the titles often and remember they exist.
- Physical limit: once the shelf is full, the next book only goes in once one comes out, either read or reclassified for donation.
- Six-month review: a book that has sat in the queue for six months without being opened probably will not be read. Reassess whether it is still worth keeping.
It is also worth separating what you are currently reading from what you have not yet opened. A tray by the armchair or nightstand for the two or three books you are reading right now keeps your current read from getting lost on the shelf among everything else.
How to preserve and clean books on the shelf
Books need ventilation, no direct sunlight, and no humidity. Sunlight fades covers and dries out pages within a few months. Humidity, especially in São Paulo, where summer is rainy, encourages mold on spines and page edges. The signs usually show up first on the bottom corners of books and on the back of shelves pressed closest to the wall.
- Distance from the wall: leave two to three centimeters between the back of the shelf and the books when possible, a little air circulation reduces mold.
- No direct sun: shelves near windows without curtains lose their covers in under a year, especially colorful spines.
- Twice-yearly cleaning: a dry cloth or soft duster on the top edges of books and on the shelves. The top edge collects dust fast and is an entry point for insects.
- Do not pack too tightly: books crammed too close together strain the spine. Leave enough room to pull one out and put it back without dragging.
- Signs of mold: a strong "old book" smell, dark stains on the edges, or pages with an odd texture. If it appears, isolate the affected book before it spreads to its neighbors.
How to set up the shelf without needing to buy anything new
After the curation, most people are surprised by how much space is left over. Before buying any organizer, set up the shelf with what you already have and see if the system works. Buying before organizing is the most frequent mistake I see in library projects: people show up with boxes and bookends that do not fit the shelves or are too big for the books that remained.
For the setup, use frequency of use as your logic: books you open regularly stay at eye and hand level. Reference books and heavy volumes go on the lower shelves. Decorative books and the ones you keep out of sentiment can go on the top shelves.
- Leave "breathing room" on each shelf: a well-organized shelf has space left for two or three new books. Without it, any purchase starts creating piles on the floor again.
- Bookends: useful when a shelf is not full enough for books to stand upright on their own. Two simple bookends solve this without much cost.
- Horizontal stacks: stacks of three to four books lying flat work well at the end of a shelf to use up leftover space, but as an occasional solution, not a general rule.
- Objects between books: one or two decorative pieces break up the visual monotony without turning the shelf into a display case. More than that starts competing with the books for space.
If, after setting things up, you notice a shelf is overloaded, adjust before deciding to buy more organizers. The system needs to work for at least two weeks before you conclude that something is actually missing.
When the shelf fills up again: the maintenance routine
The shelf fills up again because books keep arriving. Organizing once without setting up a system for what comes in and what goes out just gives the work an expiration date. The simplest rule that actually works: a new book comes in, ask whether one can leave. It does not need to be one for one, but it needs to be a regular question.
After years of organizing home libraries, the pattern I see most often is this: the person organizes carefully, feels satisfied for two or three months, starts buying books again without reviewing the system, and within six months the shelf is back to its original state. Not because they organized it wrong. Because they never built the maintenance habit.
- Check whether the TBR pile has grown beyond its designated shelf
- Set aside books that arrived without a fixed place
- Identify what has sat unread in the queue for more than six months
- Set aside at least five titles for donation
- Clean the shelves with a dry cloth
Fifteen minutes every six months is enough to maintain what you organized. A shelf with room to spare is easier to maintain than a full one, and that spare room only exists if you build the habit of taking out as much as you put in. Library organization is not the result of one afternoon of work. It is the consequence of a system you can maintain with a small, regular amount of effort.
Frequently asked questions about book organization
What is the best way to organize books: by color, author, or genre?
It depends on how you actually use your books. Organizing by genre or subject is the most functional approach for most people, you know where to look without needing to remember the author's name. By author works well for people with large collections or who always search by the writer's name. By color looks visually nice but makes it harder to find specific titles, so it works best as a visual complement on decorative shelves. A system based on reading status (read, unread, reference) is the most effective option for anyone still sitting on an accumulated to-read pile.
Do I need to buy organizers before tidying up my bookshelf?
No. Buying organizers before seeing what you actually have is the most common mistake in this process. First empty everything out, do the curation, and set aside what will leave. Only once you know how many books are staying, in which formats and sizes, can you judge whether you need bookends, boxes, or extra shelves. In many cases, the decluttering alone frees up enough space and nothing needs to be bought at all.
What should I do with books I cannot throw away but no longer read?
Create a "sentimental" category with a physical limit. Set aside one full shelf for books you keep for memory or sentimental value, with no need to justify it to anyone. The shelf's physical limit does the curation work naturally, once it fills up, something has to leave to make room for something new. Books with inscriptions from people from other phases of your life can be photographed before going to donation, you keep the memory without needing to keep the object.
How often should I reorganize my bookshelf?
With a good system in place, a bookshelf does not need frequent reorganizing, it needs small, regular upkeep. Set aside fifteen minutes every six months to check whether your "to read" pile is growing out of control, whether books arrived without a defined place, and whether anything can go to donation. Every time a new book comes in, ask whether one can leave. This simple habit keeps the shelf from returning to its original state within a few months.
