Free Symbols Library... 1000+ Scientific Symbols

[Welles]

Conceptual Diagram Symbol Libraries

"The IAN symbol libraries contain over 1000 custom made symbols (in 28 categories) designed specifically for enhancing science communication skills for the graphically challenged."

You have to see these to believe them. In order to be allowed to download them a registration is required. There are two download files available for Windows or Mac. The smaller (about 10 mbs) are just the symbols, the larger is about 36 mbs and the server speed isn't the fastest. The larger includes a searchable index and tutorials. These are for Illustrator CS (and maybe 10, I forget.)

Although I've had this set of graphics for some time, I have to say that it's a beautiful collection that is so useful, and appropriate to many of my professional projects.

Thanks a lot Welles, for bringing this to the forefront.

The IAN Symbols Library was updated yesterday. It now has 1,500 symbols and a swatch library. The Mac d/l was 31.1mb and worth every byte. If you've already registered, only a login with your e-mail address is required. If you have any browser software which blocks filtered content (not ad blockers) turn it off for the site to work properly. Here's a sampler...

I know this post is old, but just thought I'd mention that this library now has 2500 symbols and search and custom download options, and a new address:
ian . umces . edu / symbols

There is also an online vector editor to work directly with the SVG versions.

you forgot to mention
"To download symbols you need to have an account with our image library (it is completely free and only takes a minute). All past symbol library accounts have been migrated over to the image library, so you now only need one set of login details no matter how you want to download the symbols.

If you don't have an account already, please take a second to register with our image library. Once you have activated your account you will be able to return here and log in."
