Please refer to our Collections, Titles, and Ordering Information page for specific details regarding access to Project Euclid journals.
To register an individual subscription to a title, see Entering Journal Subscriptions, below.
Some publishers control access based on the years in which you were a subscriber. If you can access some years but not others, it may be that the publisher is doing this. Please check with the publisher for their online access policy.
Some publishers allow non-subscribers to purchase articles with a credit card on a pay-per-view basis.
Please Note: While Project Euclid controls access to a number of the journals available through our site, access to others is controlled by the publisher. Please see the Collections, Titles, and Ordering Information page for additional information.
Logging in to Euclid
Logging in to Euclid identifies you to the system. This may be necessary in order to view or download full text, depending on whether you have access to particular journals through an individual subscription or membership (as opposed to institutional access, for which you do not need to log in).
In the future, other services may depend on user log in, such as the ability to set interface preferences and or to register for user awareness services.
To log in to Euclid, click on the "Log in" link at the very top or bottom of the screen. After logging into Euclid, the "Log in" selection will change to "Log out." It's important to log out when you are done using Euclid so that others do not have access to your user profile.
Before logging in for the first time, you must create a user profile. See the section immediately below.
Creating a User Profile
Before logging in to Euclid for the first time, you must create a user profile, which registers your identity with Euclid. To get to this brief registration form, click on "Log in" (top or bottom of screen), and then click "create a profile here."
Condition of Use: A Euclid profile and associated User ID is for use by a single individual registrant only, and its transference to another person or group is prohibited.
You may select the Euclid User ID and password of your choice. The Euclid User ID you choose, however, must be unique within Euclid. If it is already in use, you will be prompted to select another. The User ID is not case-sensitive and may contain only the characters A-Z, a-z, 0-9, and @ . _ -. Your password is case-sensitive and may contain any standard ascii characters. You may change your password in the future, but the User ID you select cannon be changed.
While creating a Euclid profile, you may register your personal subscriptions so that you will have access to these journals. See the section Entering Journal Subscriptions, below.
You may alter or add to your user profile at any time after you create it. Do this by clicking "My profile," which will appear next to the "Log out" link at the top of the Euclid screen.
Entering Journal Subscriptions
Most visitors to Euclid will access the full-text of journal articles by means of institutional subscriptions, either to Euclid Prime or to individual titles (see Collections, Titles, and Ordering Information page). This method of access is by IP address and should be invisible to users.
Some publishers may allow individual subscribers to access their publications via a UserID/password method. To access journal content in this way, you must register that subscription in your Euclid user profile. To do this, follow the instructions below for registering individual journal subscriptions.
Before registering a subscription, you must receive from your journal's publisher a subscriber code specifically for use in Euclid. A subscriber code is unique (only one person can use it), and they are not the same as your Euclid User ID. Publishers may distribute these codes in different ways, so you will need to contact your journal's publisher if you have not received anything from them already about this. For contact information, see any journal links included on the Euclid pages for that journal.
