SNDL — the Système National de Documentation en Ligne (National Online Documentation System) — is Algeria’s national portal for accessing subscribed international scholarly databases and e-journals. It operates under the Ministry of Higher Education and Scientific Research (MESRS), through the Direction Générale de la Recherche Scientifique et du Développement Technologique (DGRSDT), and is technically administered by CERIST (Centre de Recherche sur l’Information Scientifique et Technique) at sndl.cerist.dz.
If you are an Algerian researcher, faculty member, or postgraduate student trying to reach a subscription database SNDL provides, or trying to work out why your account isn’t letting you in, this guide covers eligibility, registration, login, and what SNDL actually gives you access to — verified against SNDL’s own site.
What SNDL is for
SNDL’s stated purpose (per CERIST’s own description) is to give the Algerian higher-education and research community access to “very rich and varied national and international electronic documentation, covering all domains of teaching and scientific research.” In practice, that means SNDL is the national broker for subscriptions to international bibliographic and full-text databases and electronic journal packages — resources an individual university library in Algeria could not economically subscribe to on its own. CERIST negotiates and manages these subscriptions centrally and makes them available through the SNDL portal to eligible institutions nationwide.
Who is eligible
SNDL distinguishes two access categories, and this is the most important thing to understand before you try to register:
- Unrestricted access (accès sans restriction) — Available to all students, teaching staff, and researchers while physically on a university campus or at a research center. No individual account is required for this category; access is typically by institutional network (IP range).
- Individual-account access (accès nominatif) — Reserved for teacher-researchers (enseignants-chercheurs), permanent researchers, and postgraduate students: Master 2, Magister, and Doctorat candidates, plus final-year engineering students and, per SNDL’s FAQ, medical-science students in their 5th year and beyond. This category requires an individual account, but — per SNDL’s own “About” page — is described as accessible “without restriction of connection location,” meaning eligible account-holders are not limited to campus networks once they have a valid login.
Both categories require affiliation with an institution under MESRS (a university, university center, or national research center). SNDL is not open to unaffiliated members of the public.
How to register (inscription)
SNDL does not offer public self-service sign-up. Account creation runs through a local validator at your own institution — this is the step most first-time users miss, and it’s the reason “I can’t find where to register” is the most common point of confusion. Per SNDL’s FAQ, the path depends on who you are:
- Researchers (chercheurs) attached to a research laboratory should contact their laboratory director (directeur de laboratoire), who creates the account on their behalf.
- Teaching staff (enseignants) and eligible postgraduate/advanced students should submit their request to their university’s central library (bibliothèque centrale).
- Laboratory directors who need to become account administrators themselves send a copy of their appointment/installation decision (décision d’installation) along with a completed registration form to CERIST’s SNDL team, at the address SNDL’s FAQ gives for this purpose: [email protected]. This grants them administrator rights to create accounts for researchers in their lab.
In short: there is no direct “create account” button on the public SNDL site for individual researchers. Your account is provisioned by a person at your own institution — your lab director or your university library — who has been given administrator rights by CERIST. If you don’t know who that is at your institution, your central library is the right first point of contact.
How to log in, and what to do when it fails
Once your account exists, you sign in from the SNDL portal’s connection screen using the username and password your local administrator set up (or that you set during account creation). A few concrete points, per SNDL’s FAQ:
- Forgotten password: use the “Mot de passe oublié ?” (“Forgot password?”) link on the login screen. You’ll be asked for your username or email address plus an anti-spam/CAPTCHA code; SNDL then emails a password-reset link.
- Password requirements: SNDL requires a password of at least seven characters, mixing uppercase and lowercase letters, numerals, and special characters. If your reset attempt is rejected, check it meets all four requirements, not just length.
- If login still fails after a password reset — for example, “account not found” or a message that your account is inactive — the fix is almost never on the SNDL site itself. It means the account was never created, was created with a different email, or has lapsed. Go back to whoever provisioned it (your lab director or central library) rather than repeatedly retrying the reset flow.
- Off-campus access: for individual-account (accès nominatif) users, SNDL states access is available “without restriction of connection location” — meaning a valid personal login should work from off campus as well as on campus, without a separate VPN step. SNDL’s public documentation does not describe a specific proxy or VPN mechanism, so if off-campus access doesn’t work for a resource you’re otherwise eligible for, that is also a case to raise with your institutional administrator or CERIST directly, not something to try to work around yourself.
What resources SNDL actually gives you access to
SNDL organizes the databases and journal packages it provides under three categories, per its own resource listings:
- Ressources — the core, subscription-funded databases and e-journal packages available year-round to eligible users.
- BdDs en Test (databases on trial) — resources publishers make available to SNDL on a temporary evaluation basis, which may be added to or dropped from the permanent subscription list.
- Open Access — freely available databases and repositories that don’t require a subscription or an SNDL account at all, listed alongside the subscription resources for convenience.
Not every database’s full content is accessible under every SNDL subscription tier — SNDL publishes a “contenu” (content) sheet for each resource, downloadable from that resource’s page, describing exactly what is and isn’t covered and the years of coverage included. If a specific article or database section seems to be blocked even though you’re logged in, check that resource’s content sheet before assuming it’s an account problem — some content genuinely falls outside what SNDL’s subscription covers.
SNDL, ASJP, and DGRSDT: how Algeria’s research portals relate
Researchers in Algeria will encounter several CERIST- or MESRS-run platforms that serve different purposes and are easy to conflate:
- SNDL (this guide) gives you access to international subscription databases and e-journals — it’s a reading/discovery tool.
- ASJP (Algerian Scientific Journal Platform) is where Algerian journals themselves are hosted, and where authors submit manuscripts to Algerian journals — it’s a publishing platform, not a discovery/access tool.
- DGRSDT’s journal classification (A/B/C categories) determines how Algerian journals are ranked for evaluation purposes — a classification system, distinct from both SNDL and ASJP.
All three sit under the same ministry (MESRS) and the same technical operator (CERIST), which is why they’re frequently confused, but a researcher’s actual task determines which one is relevant: reading subscribed literature (SNDL), publishing in an Algerian journal (ASJP), or checking how a journal is classified for evaluation (DGRSDT).
Frequently asked questions
Who runs SNDL?
SNDL is run by CERIST (Centre de Recherche sur l’Information Scientifique et Technique) under the authority of Algeria’s Ministry of Higher Education and Scientific Research (MESRS), via the DGRSDT.
Can I sign up for SNDL myself, online?
No. There is no public self-registration form. Individual accounts are created by your laboratory director (for researchers) or your university’s central library (for teaching staff and eligible postgraduate students), who have administrator rights granted by CERIST.
Does SNDL work off campus?
For users with an individual (nominatif) account, SNDL states access is not restricted by connection location, so a personal login should work off campus. SNDL’s public documentation does not describe the specific remote-access mechanism (no VPN or proxy is documented on the public site) — if it doesn’t work for you, contact your institutional administrator.
I reset my password but still can’t log in — what now?
Confirm your new password meets SNDL’s requirements (seven or more characters, mixed case, numerals, and special characters). If the account itself doesn’t seem to exist or is inactive, the issue is with account provisioning, not the password — contact your lab director or central library, the people who created the account in the first place.
What is the difference between SNDL and ASJP?
SNDL gives you access to subscribed international databases and e-journals for reading and research. ASJP is where Algerian journals are hosted for authors to submit and publish. They are separate CERIST platforms serving opposite ends of the research cycle — consuming literature versus publishing it.
Is everything on a subscribed database fully accessible through SNDL?
Not necessarily. SNDL publishes a content coverage sheet for each resource; some databases are only partially covered by the national subscription. Check the specific resource’s content sheet before assuming a login problem.
