Plan the installation of your books on your premises

In-Optimo allows you to define in advance the best way to place your books, based on an import of your collections catalogue, a description of your storage spaces and your placement choices.

Obtain an immediate response for your specific needs

In-Optimo is online software that gives results in real time and is accessible directly from any type of device, with no installation needed.

View your results online or offline

The end results are:
(1) an online interface with the location of your books;
(2) a pdf plan, shelf labels and an Excel catalogue, which you can archive or rework offline.

Manage your collections over time

In-Optimo allows you to manage the location of your collections over time, whether it has been set up with our help, or whether it is a legacy of history.

Loan, weeding, arrivals and moves

Your collections are evolving, In-Optimo integrates these changes to accompany you towards a spatial layout that meets your needs.

Take back control

In-Optimo provides you with a permanent view of the location of your documents, as well as an à la carte traceability on transactions.

Guided data entry

In-Optimo guides you through the description of your storage spaces.
No need to be a topographer!


As you describe them, your storage spaces are immediately visible on the screen.


Limit the data input work:
Storage spaces are described as bays, which you can then combine and replicate.

Simple copy and paste

No tedious data entry: our interface allows you to import your books' dimensions with a simple copy and paste from your spreadsheet.

Import files

For large collections, simply import a .csv file, the standard format available in most spreadsheets and databases.

Harmonize data sources

Is your data split into several sources with different formats?
In-Optimo enables you to harmonize them.


Define your own criteria, to include only certain books in the placement simulations.


Choose simple or elaborate filing rules, or let In-Optimo save as much space as possible.


Distinguish between certain groups of books, to classify them according to different criteria.


Get a clear picture of the collection structure, with shelving plans in the form of a tree structure.


Your books are on the left, your premises on the right.
By simply dragging and dropping, you can evaluate different installation configurations.


Get an immediate overview of the space used.
Zoom in on the essential areas and see the books they contain.


Use a wide range of placement options to refine the result: margins, directions, numbering, management of books of atypical size, etc.


Find the location of any book via a search engine.


Create different scenarios to assess their consequences.

Cross over

Drag and drop to transmit the relevant choices from one scenario to another.
No double entry.


Compare the performance results of the different scenarios.


When you are satisfied with the result, get a PDF shelf installation plan, shelf labels, and a catalogue of your collections in Excel format.


Involve your team and service providers in the project.


Invite project stakeholders to access the results (in read-only mode).


Manage in real time the rights per member and per project.
Restore previous versions of a project if necessary.


Save valuable time on your projects by including up to 100,000 books in real-time simulations.

Automatic detection

When you import a book collection catalogue, In-Optimo detects directly in most cases the meaning of the different catalogue columns.


In-Optimo allows you to manually refine or correct the interpretation of metadata: book title, dimensions, units, additional information, etc.


Make the most of the information in your catalogues by finding the relevant categories in all project interfaces.
