Shutting down our preprint bots | Feb 21, 2023 | Liberate Science

“We started running Twitter bots in 2017, when Liberate Science was only a side project. First we launched the PsyArxiv bot. Later, we launched bots for the MetaArxiv (2020) and EdArxiv (2021) preprint servers. Six years in, we are shutting down these Twitter bots. You may have already noticed they are no longer posting any new preprints since February 13th (previously 9th). There are several things that motivate us to stop the preprint bots’ operations. It includes the exodus from Twitter overall; it includes the recent announcement that Twitter API access is no longer free. It includes that the community has taken it upon itself to offer replacement bots on Mastodon.?? We offered preprint bots for free all these years, but that does not mean it was free to run this. We had to run a custom RSS feed service (based on Jeff Spies’ osfpreprints-feed; run on Glitch for $99/year). Automating a bot is free and easy if there is relatively little volume. Especially for PsyArxiv, the amount of preprints grew so rapidly that we had to upgrade our automation and costs went up to ~$600 per year (using Zapier). This is also why the 1,500 free post limit proves too uncertain in the long run….”

Home – Data Commons

“Publicly available data from open sources (,,, etc.) are vital resources for students and researchers in a variety of disciplines. Unfortunately, processing these datasets is often tedious and cumbersome. Organizations follow distinctive practices for codifying datasets. Combining data from different sources requires mapping common entities (city, county, etc.) and resolving different types of keys/identifiers. This process is time consuming, tedious and done over and over. Our goal with Data Commons is to address this problem.

Data Commons synthesizes a single graph from these different data sources. It links references to the same entities (such as cities, counties, organizations, etc.) across different datasets to nodes on the graph, so that users can access data about a particular entity aggregated from different sources without data cleaning or joining. We hope the data contained within Data Commons will be useful to students, researchers, and enthusiasts across different disciplines….

Data Commons can be accessed by anyone via the tools available on Students, researchers and developers can use the REST, Python and Google Sheets APIs, all of which are free for educational, academic and journalistic research purposes….”

August OpenCon Library Community Call on Using the OpenAlex API | August 9th, 2022

Join us to learn how to use the OpenAlex API for your scholcomm research needs. OpenAlex was created by OurResearch, a nonprofit that makes open scholarly infrastructure including Unpaywall (an index of the world’s Open Access research literature) and Unsub (a tool to help librarians eliminate toll-access journal subscriptions). …”

New OpenAlex API features! – OurResearch blog

“We’ve got a ton of great API improvements to report! If you’re an API user, there’s a good chance there’s something in here you’re gonna love.


You can now search both titles and abstracts. We’ve also implemented stemming, so a search for “frogs” now automatically gets your results mentioning “frog,” too. Thanks to these changes, searches for works now deliver around 10x more results. This can all be accessed using the new search query parameter.


New entity filters

We’ve added support for tons of new filters, which are documented here. You can now:

get all of a work’s outgoing citations (ie, its references section) with a single query. 
search within each work’s raw affiliation data to find an arbitrary string (eg a specific department within an organization)
filter on whether or not an entity has a canonical external ID (works: has_doi, authors: has_orcid, etc) ….”

Usability and Accessibility of Publicly Available Patient Sa… : Journal of Patient Safety

Abstract:  Objectives 

The aims of the study were to identify publicly available patient safety report databases and to determine whether these databases support safety analyst and data scientist use to identify patterns and trends.


An Internet search was conducted to identify publicly available patient safety databases that contained patient safety reports. Each database was analyzed to identify features that enable patient safety analyst and data scientist use of these databases.


Seven databases (6 hosted by federal agencies, 1 hosted by a nonprofit organization) containing more than 28.3 million safety reports were identified. Some, but not all, databases contained features to support patient safety analyst use: 57.1% provided the ability to sort/compare/filter data, 42.9% provided data visualization, and 85.7% enabled free-text search. None of the databases provided regular updates or monitoring and only one database suggested solutions to patient safety reports. Analysis of features to support data scientist use showed that only 42.9% provided an application programing interface, most (85.7%) provided batch downloading, all provided documentation about the database, and 71.4% provided a data dictionary. All databases provided open access. Only 28.6% provided a data diagram.


Patient safety databases should be improved to support patient safety analyst use by, at a minimum, allowing for data to be sorted/compared/filtered, providing data visualization, and enabling free-text search. Databases should also enable data scientist use by, at a minimum, providing an application programing interface, batch downloading, and a data dictionary.

Analyzing Institutional Publishing Output-A Short Course – Google Docs

“This short course provides training materials about how to create a set of publication data, gather additional information about the data through an API (Application Programming Interface), clean the data, and analyze the data in various ways. The API that we’ll use is from Unpaywall and helps gather information related to the open access (OA) status of the item. This short course was created for the Scholarly Communication Notebook. If open access is new to you, we recommend checking out Peter Suber’s book Open Access. It’s concise and well written. Although things have changed since it was published in 2012, it’s a great place to start….”

Open Access Helper gets CORE API v3 boost – Research

“This time there is a release from our friends at the Open Access Helper. This is a tool that helps everyone discover a legal Open Access version of research outputs around the web. 

What is new with this version is the application’s ability to bring to researchers proactive notifications on their iPad and iPhone whenever they are browsing articles behind a paywall. 

We are really excited about this release because it is integrating our brand new CORE API (v3).  …”

Using R packages to populate IR

“Many institutions have reported that participation rates of article deposit in their IR are low regardless of their various efforts in outreach and engagement. Even when the deposit is mandated, the participation rate can still be quite low.

Once this hurdle was overcome, there is another challenge faced by the IR administrators, ensuring that the version submitted by the researcher is the appropriate version. If it is not, IR administrators would need to take additional steps to correspond with the researcher to obtain the appropriate version. Thus, increasing their administrative work load.

Therefore, some institutions had taken the pro-active initiative to complete the deposit on behalf of their researchers. This certainly is not a small undertaking. However, there are openly available R packages ( that can be used to automate some of the processes. In this page, I will summarize the steps to do that….”
