Update (May 29, 2019)
This post has been updated to reflect that the library set operations and the “perform actions on selected articles” functionality, previously listed in the “Classic features in progress” section, are now available.
ADS Classic, online since 1994, will be retired at the end of October 2019. (For more on the technical need for this upgrade, see this previous blog post.) Regular Classic users may have noticed some changes over the last few months, including an increasing number of warnings and pointers to the new ADS, meant to encourage users to begin routinely using the new interface. As of the date of this post, Classic is still available, though its remaining time is limited. Now is an excellent time for the remaining Classic users to begin to familiarize themselves with the new system and to contact us if they run into problems. Below, we list a few important things for users to know as they begin to use the new ADS.
To-Do Quick List
- Create a user account in the new ADS
- Use the transfer tool to transfer your libraries to your new account
- Check your application settings to personalize your user experience in the new ADS
- Copy any custom export formats you had set up in Classic into your application settings
- Note: some Classic features, including myADS settings, are still in progress in the new ADS; more info on these will be announced in the future
- Note: URLs pointing to Classic search results and abstract pages will not break after Classic’s retirement, and will be redirected to the corresponding pages in the new ADS
- If you need more help, check our Quick Start guides, come to our live Office Hours (live streams and recordings available on our YouTube channel), or email us
The new ADS and Classic have separate user databases, which means that user accounts will not automatically transfer from one system to the other. Users who want an account in the new ADS will need to create a new one. However, just as in Classic, users are not required to have an account to search for papers or perform most other actions. Accounts are only necessary for saving papers to libraries, more easily accessing paywalled articles through an institutional login, personalizing the user experience, and accessing our API.
As with user accounts, libraries in Classic and the new ADS are stored in different databases and will not be transferred automatically. However, we do offer a tool to help import libraries from the old system into the new one. After creating a new user account and logging in, users can link their old account to their new one and import their libraries using the import tool. There are several things to note about the import tool: all libraries in the old account will be imported, though unwanted libraries may be deleted after import. Also, the tool imports libraries, it does not link them, so changes made to libraries in the old system after import will not propagate to the new one. Other guidelines for using this tool can be found on the help page.
Users with an account in the new ADS have access to settings that allow them to personalize their user experience. For example, users who have access to electronic articles through proxy servers hosted by their institutions can set their library link servers, which enables a “My Institution” link on articles that require a login. Clicking the link redirects users to the login screen for the institutional library they previously selected; a successful login will then redirect the user to the article full text.
In addition to the library link server, users with accounts can set some application settings. These include setting a default database(s) or collection(s) for searches, such as limiting results to astronomy only by default; automatically hiding the left and right sidebars on the search results page; and defining custom formats for exporting citations.
Classic features in progress
The ADS team is hard at work adding the last few features from Classic to the new ADS. Features still in progress are:
- myADS: Setup for new users and a transfer tool for existing users, similar to that used for libraries, will be made available before the myADS email service in Classic is turned off
- Classic-style relevance sorting: A new relevance sorting method, similar to the relevance sorting in Classic, is being developed. This new relevance sort ranks more highly articles that both better match search terms and are more popular (i.e., more highly cited and/or read)
- Citation helper on a temporary set: The citation helper returns articles that are highly cited by a given set of articles but are not included in the original set. It is currently available within a library and is being considered for use with a given selected set of articles from a set of search results
- Recently read articles: Work is proceeding on allowing a user to see a list of their own recently read articles
Classic features now in the new ADS
These features were previously listed as “in-progress” but are now available in the new ADS:
- Library set operations: Set operations (union, intersection, difference, etc.) on libraries are now available; click the Actions button from your list of libraries to access this new feature. This extends the ability in Classic to effectively take the union or the difference between libraries
- Perform actions on selected articles: Second order operations, such as retrieving the references of selected articles, are now available for a subset of articles manually selected from the search results set. To access this feature, select the desired articles in the search results, then click the Explore menu and choose the desired operation
To make it easier to start using the new ADS, the ADS team has prepared a range of supports to help users make the transition:
- The Quick Start guides are a set of simple written tutorials to walk users through basic tasks in the new ADS, such as finding a paper using an author name and the publication year
- The FAQs and the data and curation FAQs answer some frequently asked questions about the new system
- Users who prefer a short video demo to reading documentation can find that at the front of our help pages
- The ADS team is hosting a monthly series of talks, called ADS Office Hours. Talks are 30 minutes and are designed to introduce users to new or advanced features on the website. The talks are followed by unstructured drop-in time for users to ask questions or get a demo of unfamiliar features. Users can attend in person at the Center for Astrophysics in Cambridge, MA, USA, or watch the talks via live stream on our YouTube channel. Users wishing to join after the talk for the informal question and demo portion of the session can connect via Google Meet. Recordings of the talks will be available on our YouTube channel after the conclusion of the talk. Previous talks are also posted on our help pages. Upcoming talks are announced on our Twitter feed.
And as always, we welcome questions and feedback from our users via email.
