Questions by Topic

Subscription Types

Why should I get an individual subscription?

Individual subscribers have the advantage of password access to the journal from any computer connected to the Internet. Institutional subscribers must use their institution's network for home or travel access.

How do I purchase an individual subscription?

Send orders and correspondence to the contact information at the bottom of this page. Pay by personal check, money order, or credit card, and state that your subscription is for personal use only. Individual subscriptions may not be used for a library.

How do I purchase an institutional subscription?

1. Follow your usual "new serial" ordering procedures to subscribe to PNAS:

  • Send payment to your subscription agent, or send payment to PNAS by check, credit card, money order, or draft.
  • Please note: New subscribers cannot access PNAS until Step 2 below is completed. Step 2 is not necessary for renewing subscribers—your expiration date will be revised to the end of the new calendar year once your renewal payment is processed.

2. New subscribers only—once PNAS has received your payment, you will receive an email with instructions to activate your subscription via an online form. Your institution will not have full access to PNAS until you complete this step. You will need:

  • Your institution's IP addresses
  • The name, title, phone, fax, and email of the institutional contact person for the subscription
  • Your access code (included with your activation email)

Payment can be accepted through subscription agents, but online registration must be completed directly by the subscriber.

"Authorized users" are authenticated, current, full- and part-time students, employees (including faculty, staff, affiliated researchers, independent contractors, and walk-in users), and other individuals who have legal access to the subscriber's facilities and computer network. Remote access is allowable for authorized users only if they are authenticated through a secure network. Open proxies and other nonauthenticated proxy servers are prohibited.

An "institution" is all parts of an organization that report to the same Chief Academic Officer or Chief Executive Officer. For multicampus academic institutions, each organization listed in the Directory of Higher Education is a separate institution, and requires its own site license. For the purposes of these terms and conditions, academic law libraries and academic medical libraries are considered part of a university and are part of an institution only if they report to the same institutional Chief Academic Officer.

Do you offer a student/postdoc subscription?

No.

Subscription Access and Management

How do I activate a new subscription?

Once PNAS has received your payment, you will receive an email from PNASsubsdept@nas.edu with an access code. After you receive the email, review the PNAS Online Subscription Agreement. By activating your online subscription, you agree to all subscription agreement terms and conditions.

Next, you must ACTIVATE your online subscription using the links below.

I forgot my access code

For new subscribers, your access code appears on the activation email sent to you by PNAS confirming your subscription. If you cannot locate your access code, please contact PNAS.

Do I need to activate my subscription again if I renew?

If you renew an active subscription, you will not need to repeat the activation process. The expiration date for your online record will be updated after your renewal is processed.

Can my institution subscribe for both print issues and online access?

Print subscriptions were discontinued in 2015, and PNAS subscriptions are now online-only.

Who from my institution can access PNAS?

A site license permits unlimited simultaneous Internet access to PNAS by authorized users generally at one location (the employees, faculty, staff, and students officially associated with the subscriber, and authorized patrons of the subscriber's library facilities that are administered from the subscriber's site or campus) through the use of the institution's IP address. Authenticated and authorized users may access PNAS from other locations (e.g., through dial-in, telnet, etc.). For institutional online subscribers, there are no user names or passwords to remember, and there is no limit on the number of users from your institution who may access PNAS simultaneously.

If our PNAS subscription expires and we reinstate our subscription later, will we have access to all available years of the electronic edition?

While you have a paid and activated subscription to PNAS, you will have access to all content in the electronic database. When your subscription expires, you will still have access to free back issues (all PNAS content is free after 6 months).

PNAS does not officially offer perpetual access. However, cancelled subscribers will eventually regain access to recent articles 6 months after their publication dates

As an individual subscriber, what do I have access to on the site?

Individual subscribers receive access to the abstract, full text, or PDF version of any article published in an issue or in Latest Articles from any computer connected to the Internet, via password access.

As an institutional subscriber what do I have access to on the site?

Institutional subscribers receive access to the abstract, full text, or PDF version of any article published in an issue or in Latest Articles from any computer connected to the Internet, via their institution’s network.

Where can I view institutional usage reports?

View Institutional Usage Reports.

As an NAS member, what do I have access to on the site?

NAS members receive access to the abstract, full text, or PDF version of any article published in an issue or ahead of print from any computer connected to the Internet, via password access. Usernames and passwords are emailed to members by PNAS. If you cannot locate this information, please refer to the contact information at the bottom of this webpage.

Will I receive a password? May I share my password with others, or is use limited solely to me?

If you are not an NAS member and are starting a new individual subscription, you will receive activation instructions via email after PNAS receives your payment. You will receive an access code to activate your account, and will be prompted to create a username and a password. Activation is a one-time process for new subscribers, and you will retain the same login credentials year to year. You are the only one licensed to use your login credentials; please keep them confidential.

How do I login with my subscriber info?

Please visit our login page.

I forgot my password, or I want to change my password.

Manage your password.

How can I view or change my account information?

Manage your account.

How do I cancel my subscription?

Cancellations must be received by April 30. Please allow 6 weeks for processing your request. Refunds will be issued for the unused portion of the subscription. All refunds may be subject to a $25 processing fee. Send cancellation or refund requests to the contact information at the bottom of this webpage.

What content is freely available to nonsubscribers?

How can authorized users access PNAS content while off-site?

An institution may allow remote access to authorized users through a secure network. Alternatively, users may utilize Campus-Activated Subscriber Access (CASA), developed by HighWire Press and Google Scholar. To activate CASA, a user must first search for PNAS content on campus, then search for the same PNAS content while off campus. Google Scholar will associate the institution’s site license with the user’s device and/or Google account, thus starting 7 days of access to all PNAS content while off campus. The user can renew full access for another 7 days by continuing to access PNAS access. Otherwise, they will need to restart the process after the 7-day period by returning to campus. Please visit Campus Activated Subscriber Access (CASA) for more information.
