This month @usnatarchives #hashtagparty is #ArchivesWomenInSTEM (forgive us for putting the hashtags in the text, Tumblr friends) — so we thought we'd highlight the brilliant sister of astronomer Tycho Brahe, Sophia Brahe. She was a horticulturist fluent in astronomy, medicine and chemistry and she often worked with her scientist brother.

Women in Science Day (psssst... get a behind the scenes look)

Happy International Day of Women and Girls in Science! At the National Archives, women bring considerable technical skills to their work every day, including the women of our Heritage Science Research and Testing Lab.

Lindsay Oakley and Cancy Chu test a new colorimeter instrument with a sheet of color standards. Understanding how color shifts over time is an excellent way for scientists to see how materials change as they age and ensure we provide the best possible preservation conditions for records like documents and photographs.

Jennifer performs X-Ray fluorescence (XRF) spectroscopy to identify the pigments used in this watercolor of Fort Pierre. This supported its safe conservation treatment before being displayed as part of the “All American” exhibit.

How does @USNatArchives decide how long a document can be on display?

Scientists and conservators use another type of artificial aging test, this time with light. This micro-fadometer uses high-intensity light for a short time, measuring changes undetectable to the human eye. This information helps us create light budgets for items as they are displayed or used for research.

Lindsay Oakley, NARA’s Director of Heritage Science Research and Testing explains what heritage science is and introduces the scientists and research projects that make the lab such an important part of NARA’s preservation efforts.

Can you recommend any active history blogs?

I don't follow all that many blogs, so I'm sure some of my readers can share their recommendations in the replies. Of the blogs that I do follow, here are a few activate sites that regularly update with some great material:

•The Richard Nixon Presidential Library and Museum (@richardnixonlibrary)

•The California State Library (@californiastatelibrary)

•The Franklin D. Roosevelt Presidential Library (@fdrlibrary)

•Today's Document from the National Archives (@todaysdocument)

•The National Archives (@usnatarchives)

I really wish that the LBJ Library (@lbjlibrary) still updated their Tumblr regularly because they used to post some interesting stuff. The Gerald R. Ford Presidential Library and Museum (@fordlibrarymuseum) has also been inactive for a few months, but they were one of my favorite things to see on my dashboard when they posted regularly. A few years ago, the National Archives actually started an awesome Tumblr called Our Presidents (@ourpresidents) that was like the mothership for all of the other Presidential Library blogs in the NARA's Presidential Library system. It was a GREAT idea and one of my favorite blogs, but it just stopped posting a couple years ago. I wish they would get that one going again. I think those inactive sites still have their old posts and archives available, so you can still go back and see what we're missing.

Like I said, I'm sure some of my readers have better suggestions than I do about this that they can share in the replies, so what are some of your favorite history blogs?

Introducing Collections

Hello again, Tumblr. Labs division here!

A while back, we announced our comeback as a new team that would imagine big ideas for Tumblr—and would build them in public (aka with you). We recently announced our first failure, and today we're very excited to announce our first possible success!

A bit of context

As we've said before, an essential part of how we're working in Labs is speaking to people who use Tumblr pretty much on a daily basis and those who don’t use it at all.

In those interviews and focus groups, we learned that curating the Tumblr experience around different interests and fandoms is a big part of making Tumblr feel like your own space — and one of the main ways you do that is through blogs and tags (be it following or creating them).

So here at Labs we're working on ideas to help you curate the content you care about, and to help share what makes your experience fun with other people, even if they are not on Tumblr already.

Ok, but what's the idea?

Have you ever put together a song playlist to listen to when you're in a certain mood, or share with a specific friend? Or sent them books you know they'll love? Now imagine if you could do that with blogs and tags on Tumblr…

Maybe you're a veteran in a fandom and have the best recommendations of who to follow for your followers. Or your best friend won't join Tumblr because they don't know that their favorite TV show is actually really popular here. Or maybe you want to curate and browse content from a specific fandom, or a group of your mutuals, your own way.

That's the idea behind Collections!

You can check out that example collection on the web here!

We want your help

The first way we're testing Collections is by inviting some of you to create your own and share with followers and friends—they'll be able to follow all the blogs and tags in your collections. So we're looking for volunteers!

You want to help? Great! Here's what you need to do:

Come up with your own Collections of blogs and tags, write it down somewhere. Focus on introducing people to Tumblr or recommending stuff to your followers. What would you want them to first see on your version of Tumblr?

Come up with a name, cover image, and description for it. Also try to think of who you would send your collection to, and where you might post about it.

Write out that idea as a reply or reblog on this post!

We’ll give it a few days, and pick a handful of people to play with Collections. We'll let you know. Then we’re off to the races!

If you decide to participate (and get selected), please note that this early release won’t work on the apps yet, only in your web browser. 

What happens next?

Our goal is to keep working on improving and adding Collection functionalities while you test what we've built (and share your feedback with us).

Next we’re exploring making a collection something you can follow on Tumblr, as a way to curate Tumblr around your many interests and moods, and to give you more freedom to curate content on your dashboard.

And if this idea is not for you, remember we have many more experiments in progress, so stay tuned!

With love,

Labs division
