September 2026: Building permit and SEO data, plus citation exports
This month's headline is new building permit and search data, plus citation exports for your projects, easier ways to get data, and a round of access and download fixes.
DATA UPDATES
New data added
- ATTOM Building permits - U.S. building permit data, with supplementary tables for permit status and type of work. Permits link to Tax Assessor and other ATTOM property data.
- Serpstat search visibility - data on nearly a million domains: domain ratings and traffic, search rankings, Google AI Overview citations, and backlinks.
Updates to existing data
- LinkUp Job Records - New Skills and AI Skills tables tag each job posting with the skills it lists and whether it requires AI skills. Tagging is by researchers at UMD's Robert H. Smith School of Business.
- Consumer Address History - InfutorData's Consumer Address History is now exclusively available to institutional subscribers. Impacted subscribers have been contacted and can keep using it for research in progress.
PRODUCT UPDATES
Citations and projects
- Projects can now export dataset citations as BibTeX, RIS, or EndNote files.
- Data product pages with several citations show one up front, with the rest behind "Show all citations."
- A DOI is now optional for Submitted and Published projects, and a paper link is only required once a project is Published.
Getting data
- Get Data can save a dataset to several projects at once.
- If your access to a dataset comes from more than one place, such as your plan and your team's, Dewey now combines them.
- The customization page now shows how many daily previews you've used and when they reset.
- You can now change your sign-in email from your Profile.
BUG FIXES
- Fixed access not coming back automatically after a past-due subscription was paid.
- Fixed Get Data appearing greyed out for some university users.
- Fixed sign-in being blocked for some users with more than one login method.
- Data samples now list columns in the table's order instead of alphabetically.

August 2026: Auto, labor market, and e-receipt data, plus a Catalog reorg
This month's headline is a reorganization of the data catalog around datasets, plus new ways to document your catalog, a cleaner Projects experience, and a long list of reliability fixes across the Dewey platform.
DATA UPDATES
Three new data providers added
- Automotive - MarketCheck scans over 100,000 dealership websites across the US and Canada daily, capturing what's sitting on the lot and what's selling at the VIN level. Already included in every Dewey subscription.
- Labor market and workforce - Lightcast labor market and workforce data powers academic research on labor economics, workforce skills and education, and regional economic analysis. Occupation and job postings data is now available through Connect, and company and office data covering over 200 million companies worldwide comes included in the Dewey Subscription.
- E-Receipt - Measurable AI's Shopee E-Receipt Data and Panelist Info are now available in Connect on the Dewey platform. Tap into millions of anonymized e-commerce transactions across Southeast Asia and Brazil.
Free data added
- IPinfo's lite geolocation data is now downloadable straight from the Dewey platform. It maps the entire IPv4 and IPv6 address space to country and ASN, about 35 million rows, refreshed daily, and completely free.
PRODUCT UPDATES
Data catalog reorganization
- New dataset listing view shows all primary and supplementary tables on a single dataset, making it easier to visualize the relationship between tables.
- Documentation and changelogs are now shown at the dataset level.
- Codebooks and other resources are now available within the Dewey platform, on the documentation tab for each dataset (where available).
- Tables added to a project are now grouped and summarized by dataset, with combined "last refreshed" and "last accessed" info.
- AI search dataset recommendations on the Discover page are now grouped by dataset, showing table and paper counts and category tags at a glance instead of a flat list of individual tables.
BUG FIXES
- Fixed formatting of links and text in discussion replies.
- Fixed projects not sorting correctly by "last accessed."
- Fixed a bug where re-verifying an email address could occasionally cause page-load failures and brief slowdowns across the site. Added additional safeguards to prevent this from happening in the future.
- Project-related download errors now show the actual reason (e.g. "add this dataset to your project first") instead of a generic message.
