Madrid’s public library card is free, and the adult application requires permanent or temporary residence in a municipality within the Community of Madrid. You can apply through a municipal library or the relevant online procedure. Once registered, your reader number gives you access to borrowing, account management and eBiblio Madrid. Your nationality or the language you speak does not replace the residence requirement.
Start with a small goal: a novel, a cookbook or an audiobook. Choose something you actually want to read, get your account working and learn how to return it. The rest becomes useful when you need it.
Eligibility: the region matters, not just Madrid city
The City of Madrid adult application covers people living permanently or temporarily in the Community of Madrid. The residence declaration concerns a postal address in a municipality in the region. Madrid city is only one of those municipalities. If you are living in the region temporarily, ask how to record your circumstances accurately on the application.
Someone living outside the region should not assume that interest in the digital catalogue makes them eligible. A passport or NIE can identify you, but does not by itself establish residence. If you are visiting and are unsure how your stay is treated, ask the library about your circumstances before applying. For a reading-room visit, ask about access to that specific space separately.
The card belongs to the Carné Único regional library system. If you already have a card from a participating service, check that account first. Moving to another neighbourhood or visiting a library run by a different administration is a reason to update or use your existing registration, rather than automatically applying for another reader identity.
Applying in person or online
At a municipal library
The municipal registration guidance requires an official identity document for an in-person application. Accepted documents include passports, DNI and NIE, among others. It describes in-person registration as immediate. Bring accurate contact details and an email address you use, and ask staff to confirm that they entered it correctly.
Choose a branch through the official library finder and check its individual listing before you leave. Look at that day’s hours, access information and any notices. A branch near work or on a regular journey may be easier to use than the nearest one to your home, especially when you need to return a book.
Through an online procedure
The city application requires electronic identification and a signature. The Community of Madrid online card procedure is a separate administrative route for the unified card, with its own instructions. Follow the channel you choose and keep the submission receipt. Submitting a form is not the same as having an active borrowing account.
The regional Reader Portal explains how to use the card from your account without relying on a plastic card. Save your reader number and check that you can sign in. If you prefer using your phone at the desk, ask staff how to display your card barcode correctly.
Physical borrowing and eBiblio are different services
| Your goal | Start here | Check |
|---|---|---|
| Borrow a printed book | The public-library catalogue. | Branch, copy, availability and return date. |
| Borrow an ebook or audiobook | eBiblio Madrid. | Format, availability and the service’s loan period. |
| Read or study at a branch | That library’s listing and rules. | Space, access arrangements and any specific conditions. |
The municipal lending page allows up to six printed books for thirty days, subject to its borrowing and renewal rules. Do not apply those limits to digital loans. Reference material may be for consultation only; a catalogue entry is not a guarantee that a copy can leave the building with you.
eBiblio Madrid requires the unified library card for borrowing digital material. Sign in with your reader number and the corresponding password. Your card must be current and free of loan-blocking sanctions; its number alone does not guarantee access. An account with another reading platform, or a registration link on a website, does not replace library registration.
Make your first visit worthwhile
- Bring a few possibilities. A title, an author and a subject give you alternatives if the book you had in mind is already on loan.
- Check the actual edition. Look at language, print size and format. A familiar cover is not enough to identify the version you want.
- Give staff a useful starting point. “A short novel in English” or “a practical beginner’s gardening book” is easier to work with than “something good”.
- Read a few pages. Choose a book whose voice or layout you enjoy. There is no need to borrow the maximum allowance on your first day.
- Check the return details. Save the due date from the actual loan and ask where you can return it. Do not assume every branch accepts every return.
You might choose one book for pleasure and another to browse more slowly. If you enjoy finding authors by looking through shelves, a walk around Madrid bookshops can complement your library visit. Borrowing and buying can fit different reading plans without turning either into a test of how serious a reader you are.
Get your digital access working before you rely on it
The catalogue user area shows loans and reservations and lets you update your email and password. Try a simple check: sign in, identify your record and look at the registered email address. If there is a problem, note the exact error and ask the library for help. Another application is unlikely to clarify an existing account issue.
For your first digital loan, choose an available title and a device you already use. Read the format instructions before borrowing. If you want to use a dedicated ereader, confirm compatibility first; an ebook label does not mean every device and app can open it. For a new ereader setup, follow the current eBiblio instructions: Adobe Digital Editions login requirements changed in June 2026.
Useful questions before applying
Does the card work at every library?
It works at services participating in the unified-card scheme. University, specialist and out-of-region libraries may have their own registration and access arrangements. Treat the participating network as the boundary, rather than assuming any library will accept it.
What about a child’s card?
Municipal guidance separates children’s cards from registration for ages fourteen to seventeen and sets out parental or guardian authorisation. Permission to use Internet services has additional requirements. Read those separately before preparing the adult’s documents.
Should I apply again if I forget my password?
Try password recovery through the catalogue or ask the branch to help identify your record. Restoring access to an existing registration is a more useful first step than repeating the application.
