Openverse is a tool that allows openly licensed and public domain works to be discovered and used by everyone.
Openverse searches across more than 800 million images and audio tracks from open APIs and the Common Crawl dataset. We aggregate works from multiple public repositories, and facilitate reuse through features like one-click attribution.
Currently Openverse only searches images and audio tracks, with search for video provided through External Sources. We plan to add additional media types such as open texts and 3D models, with the ultimate goal of providing access to the estimated 2.5 billion CC licensed and public domain works on the web. All of our code is open source and can be accessed at the Openverse GitHub repository. We welcome community contribution. You can see what we’re currently working on.
Openverse is the successor to CC Search which was launched by Creative Commons in 2019, after its migration to WordPress in 2021. You can read more about this transition in the official announcements from Creative Commons and WordPress. We remain committed to our goal of tackling discoverability and accessibility of open access media.
Openverse does not verify licensing information for individual works, or whether the generated attribution is accurate or complete. Please independently verify the licensing status and attribution information before reusing the content.
Life is hard. Some days are at the absolute limit of what we can manage. Some days are worse than that. Eating—picking a meal, making it, putting it into your facehole—can feel like an insurmountable challenge. We wrote this cookbook to share our coping strategies. It has recipes to make when you’ve worked a 16-hour day, when you can’t stop crying and you don’t know why, when you accidentally woke up an Eldritch abomination at the bottom of the ocean. But most of all, this cookbook exists to help Sad Bastards like us feel a little less alone at mealtimes.
The Sad Bastard Cookbook is funny, realistic, and kind. It’s vegetarian/vegan. It’s a community-built project. And the e-book is free. It’s hard to survive late capitalism and we want to help.
Subscribe to the newsletter, download the free pdf, and print it. We’re cool with that. We made it legal with Creative Commons (4.0-BY-NC), but if you get a thrill from breaking the law, you can pretend it’s not.
Textbooks in the Open Textbook Library are considered open because they are free to use and distribute, and are licensed to be freely adapted or changed with proper attribution. The criteria for including new textbooks in the Open Textbook Library are:
- All content must be openly licensed. We accept textbooks licensed with GNU and Creative Commons (CC) licenses, with the exception of the CC ND (No Derivatives) component. CC BY is recommended. Go to Creative Commons for more information about selecting a license for your work.
- Must be a complete textbook available as a complete portable file (e.g. PDF, EPUB).
- Must be in use at multiple higher education institutions, or affiliated with a higher education institution, scholarly society, or professional organization.
- Must be an original textbook (not a derivative of another textbook). Possible exceptions to this criteria are modifications that reflect the needs or context of an entirely new audience. For example, the textbook has been changed in such a significant way that it is now relevant to a new country, profession, or has been translated into a new language. Authors or publishers will be asked to demonstrate significant changes to the original text.
Conformal Decals adds a set of decal stickers to the game Kerbal Space Program (KSP), as well as providing a framework for creating your own decals which conform to the surface of the parts they are attached to.
This means that you can do other stuff with them, like make your own stickers and icons and suchlike. Especially interesting because it has the Semiotic Icons that were used in Alien.

CORE (Curriculum Open-access Resources in Economics)
CORE’s vision is that a radically transformed economics education can contribute to a more just, sustainable, and democratic world in which future citizens are empowered by a new economics to understand and debate how best to address pressing societal problems.
Since Yahoo killed off their Where-On-Earth (WOEID) API service, it hasn't been possible to use it to get WOEID maprefs for certain APIs. Thankfully, some kind soul uploaded it to the Internet Archive.
The contents are five TSV (tab separated value) files, a Readme.txt file, and a license.txt file.
If you want to read them into a SQLite database (and you'll need to set a primary key on each table), do this:
user@host: sqlite3 geoplanet.sqlite
sqlite> .mode tabs
sqlite> PRAGMA foreign_keys=off;
sqlite> CREATE TABLE adjacencies (id INTEGER PRIMARY KEY, Place_WOE_ID TEXT, Place_ISO TEXT, Neighbour_WOE_ID TEXT, Neighbour_ISO TEXT);
sqlite> .import geoplanet_adjacencies_7.10.0.tsv temp_adjacencies
sqlite> INSERT INTO adjacencies(Place_WOE_ID, Place_ISO, Neighbour_WOE_ID, Neighbour_ISO) SELECT Place_WOE_ID, Place_ISO, Neighbour_WOE_ID, Neighbour_ISO from temp_adjacencies;
sqlite> drop table temp_adjacencies;
sqlite> CREATE TABLE admins (id INTEGER PRIMARY KEY, WOE_ID TEXT, iso TEXT, State TEXT, County TEXT, Local_Admin TEXT, Country TEXT, Continent TEXT);
sqlite> .import geoplanet_admins_7.10.0.tsv temp_admins
sqlite> INSERT INTO admins(WOE_ID, iso, State, County, Local_Admin, Country, Continent) SELECT WOE_ID, iso, State, County, Local_Admin, Country, Continent from temp_admins;
sqlite> drop table temp_admins;
sqlite> CREATE TABLE aliases (id INTEGER PRIMARY KEY, WOE_ID TEXT, Name TEXT, Name_Type TEXT, Language Text);
sqlite> .import geoplanet_aliases_7.10.0.tsv temp_aliases
sqlite> INSERT INTO aliases(WOE_ID, Name, Name_Type, Language) SELECT WOE_ID, Name, Name_Type, Language from temp_aliases;
sqlite> DROP TABLE temp_aliases;
sqlite> CREATE TABLE changes (id INTEGER PRIMARY KEY, Woe_id TEXT, Rep_id TEXT, Data_Version TEXT);
sqlite> .import geoplanet_changes_7.10.0.tsv temp_changes
sqlite> INSERT INTO changes (Woe_id, Rep_id, Data_Version) SELECT Woe_id, Rep_id, Data_Version from temp_changes;
sqlite> DROP TABLE temp_changes;
sqlite> CREATE TABLE places (id INTEGER PRIMARY KEY, WOE_ID TEXT, ISO TEXT, Name TEXT, Language TEXT, PlaceType TEXT, Parent_ID TEXT);
sqlite> .import geoplanet_places_7.10.0.tsv temp_places
sqlite> INSERT INTO places (WOE_ID, ISO, Name, Language, PlaceType, Parent_ID) SELECT WOE_ID, ISO, Name, Language, PlaceType, Parent_ID from temp_places;
sqlite> drop table temp_places;
sqlite> PRAGMA foreign_keys=on;
sqlite> .quit
I would also recommend cleaning up after yourself:
user@host: sqlite3 geoplanet.sqlite
sqlite> VACUUM;
sqlite> .quit

The collaborative, web-based, massively multiplayer game Glitch began its initial private testing in 2009, opened to the public in 2010, and was shut down in 2012. It was played by more than 150,000 people and was widely hailed for its original and highly creative visual style.
The entire library of art assets from the game, has been made freely available, dedicated to the public domain. (CC0)
Github repo for a book that teaches you how to write web apps using Go.
The Internet free music archive. Just what it says on the tin.
The official website for a transhumanist-themed RPG which is light on the rules but heavy on the "Wow, my character can do that?!" factor.
The book that started the Creative Commons movement.
A far future RPG in which the players play field agents keeping the peace between a dozen civilizations by any means necessary throughout the universe. Also has strong themes of political intrigue, wonder, and responsibility. Published under the Creative Commons v3 license, though you can purchase PDFs of it from DriveThruRpg.com or buy dead trees from lulu.com if you want to support the project.
A Creative Commons-licensed book by Al Sweigart that teaches programming in Python through writing your own video games. Full source code is included.
A CC-licensed cheatsheet for building with and programming the Arduino.
The DIYLILCNC is a fully functional, open source 3-axis CNC that you can build with basic tools and parts that can be locally sourced. The idea is that you develop a 3D design in a CAD application, put feedstock into the CNC, and print your design to it, and it cuts and grinds away everything but what your design is supposed to be. Total cost of construction is about $700us. You can download the plans and DXF template files from the website for free (they have a CC-BY-SA license).
Wikihouse is an archive of open source building designs contributed by engineers and architects around the world. Each design is peer-reviewed and analyzed by others to ensure that the designs are sound. Some of them have already been built and the results posted for further review. The design principles include being as easy to build by people with minimal formal training, as energy efficient as possible, and easy to modify to fit a particular purpose. All designs are made in Google Sketchup and can be cut with an automill if available.
A pair of books licensed in the Creative Commons (BY) which talk about the architecture of open source software. The core developers of four dozen projects talk about how their software is structured, and most importantly why. They were written so that F/OSS developers wouldn't have to learn by reinventing the wheel, instead there would be a reference.
There are two books, which you can read online and download for free. Or you can buy them as Kindle editions (the proceeds go to Amnesty International).
A collection of JavaScript and CSS progress bars that can be incorporated into websites. Creative Commons.
The Universal Construction Kit is a set of open source components that you can fab on a 3D printer, which allows the user to hook together different construction kits without duct tape or twist-ties. The components make it possible to use Lego, Duplo, K'Nex, Lincoln Logs, and other construction kits in the same project simultaneously.
The whole set can be downloaded as a .zip file from the website.
The .stl files carry a Creative Commons By Attribution/Noncommercial/Share Alike v3.0 license.
Note that the .stl files are in inches, not mm. Double-check the settings of your 3D printer before fabbing!
