Subscriptions: Terms of service

See also our SERU option.

Only qualifying institutions are required to purchase a PhilPapers subscription. A qualifying institution is an institution that grants a BA in philosophy or similar degree (or higher degree) and is based in a country with a 2009-2013 GDP per capita of at least 30,000 Int$ according to the World Bank.

When you purchase a subscription to PhilPapers, you enter into the following agreement with the PhilPapers Foundation, a not-for-profit corporation based in London, Ontario, Canada.

Rates and duration

Except for UK universities, the annual rates for qualifying institutions are based on the highest degree in philosophy offered:

Tier Highest philosophy degree offered Annual rate
Tier 1 BA or equivalentUS$564
Tier 2 MA or equivalent (e.g. M.Phil)US$906
Tier 3 PhD or equivalent (e.g. D.Phil)US$1408

In consultation with JISC, UK universities are assigned tiers based on the number of full-time faculty members specializing in philosophy (relevant faculty size). The minimum relevant faculty size for tiers 2 and 3 is 6 and 13 (inclusive), respectively. We provide estimates of UK tiers on this page. These estimates are derived from PhilPapers user statistics. UK universities are billed based on the tier estimates on this page at the time of invoicing. It is the responsibility of subscribing universities to inform us of tier corrections as required. If an invoice recipient does not correct the tier used by the due date on the invoice, the tier will be deemed correct for the period covered by the invoice. The cutoff points are calibrated to yield a price structure comparable to that in place for US universities. The above rates will increase by 3.5% on the coming April 1st.

Please note that while non-qualifying institutions have free access, we cannot currently provide them with institutional accounts. We are working on low-cost subscriptions for non-qualifying institutions that would like to have the benefits of institutional accounts.

Multi-campus universities and consortia are required to purchase a subscription for each campus that is an institution in its own right. A campus is considered an institution in its own right for subscription purposes if it appears on this list, which we reserve the right to amend at any time. If your organization is not accurately represented in this list, please contact us at to request an amendment.

Canadian subscribers are invoiced in CAD; other subscribers are invoiced in US dollars. HST/GST applies for Canadian subscribers.

A new subscription is valid for a year from the day the subscription is activated. A renewal is valid for a year after the expiry day of the previous subscription.

Subscription fees are payable within 30 days of the beginning of a subscription period. We will automatically invoice you for a new period at the end of your current subscription. If you wish to cancel your subscription, please advise before the end of the current period.

Member Institutions and Affiliated Users

Your subscription extends to all and only the institutions for which you have paid the subscription fee (Member Institutions) and their affiliate members (Affiliated Users). An individual shall be considered an Affiliated User of a Member Institution when a) they are employed by or participate in a training program at the Member Institution or b) they are accessing PhilPapers using the Member Institution's network and are a legitimate user of this network. A user shall be considered a legitimate user of a Member Institution's network if they are authorized to use the network in virtue of a role they play at the Member Institution or in virtue of the Institution's policy with regard to walk-in users using its network on premise.

Access privileges

Your subscription gives your Affiliated Users access to PhilPapers (including all the services hosted at and all subdomains) when accessing PhilPapers via the IP addresses associated with their accounts. Access will only be granted for IP addresses specified by Member Institutions. It is the responsibility of Member Institutions to submit their IP addresses as instructed upon the activation of a subscription. Subject to our terms and conditions of use and the capacity of our servers, we impose no limits on the numbers of Affiliated Users or IP addresses that can connect to PhilPapers from any given Member Institution.

Disabilities Act

The PhilPapers Foundation endeavours to provide all Affiliated Users with a user interface compliant with the Americans with Disabilities Act (ADA) through the use of best practices and accessibility standards.

Terms and conditions of use

The regular terms and conditions of use for PhilPapers and associated services apply to Affiliated Users and Member Institutions.

Additional services

From time to time, exclusive services will be offered to Member Institutions. The Foundation reserves the right to add to, modify, or cancel these services. The Foundation reserves the right to charge for additional services offered to institutional users in the future.


We reserve the right to make minor amendments to these terms without notice, so long as the changes are not detrimental to Member Institutions.
