The map is below, but I think it's easier to click the link above and use the map in its own dedicated window. If you're on a phone, after you go to the map, click on the little white box in the upper right and you'll see it in Google Maps, which gives a different view.
For the map below you can access the legend by clicking on the little "screen with arrow" icon in the upper left.
Click on a location in the legend or on the map for an address, description, and picture. Also, more community maps below.
Please send your additions and corrections to the map to me.
If you want to spread the word, here's a page of 10 "business cards" for printing. You can also get a single card image, or just the QR code. Point your phone's camera at it and you'll be led to https://bit.ly/boxesmap. (If you want to make your own QR code for anything, it's free and easy.)
This map contains many more free library boxes than the official Little Free Library map. (Note: there's also now a Little Free Library app, which appears to be missing even more boxes.) Boxes not mapped there are shown with a darker blue marker. If you own a box and want to add to or change your description, just let me know.
Pantries: this map shows just the micro-pantries and community fridges where people can conveniently donate food. For larger food pantries, search your address on this site. Medford has a unified site for food resources. For Somerville, you can post pictures of the status of any community fridge or micropantry on this public Facebook group, and there's one for the blessing box in Davis Square; for Medford, there are Facebook groups for the community fridge and for micropantries. You can find out more about the micropantry movement from this research article (which includes a photo of a micropantry in Medford).
Seed libraries: Arlington has a seed library, based at Robbins library. Anyone can take seeds, even if you don't have a library card. The other seed libraries I know are in Little Free Library form, at 25 Edward St, Medford and 301 Pleasant St, Belmont (on the border with Arlington). The Belmont box is run by the Mystic Charles Pollinator Pathways Group. Note the legend of our book map here also notes a few other types of boxes at the top: art, media, games, etc. If you know of any other specialized boxes or sites, email me.
Note there is also the Mini Pantry Movement map, which is missing a lot of boxes. If you own a minipantry, please do add it to their map. If you are thinking of creating one, they have lots of information about doing so.
To verify boxes, we visit them. Here's one photo collection - after clicking on a picture, click the info (i) icon in the upper right to see the location.
I've also been enjoying adding "if you're here, you might want to check out such-and-so" descriptions to a few boxes as I go, such as local public art, koi ponds (there is one near the Jay St box in Somerville), etc. But, I hardly know everything about all locations, so feel free to clue me and everyone else in.
This is a copy of the original map created by Kami Ford. She has moved away so I'm coordinating maintaining it. A bunch of people are helping out - you can, too! As well as adding new boxes, there are errors on this map which we are weeding out. For the original (now unmaintained) map by Kami, go here.
Thanks to all who have sent new locations and corrections. And more thanks to all of you who have built and maintain these wonderful resources that add so much to our communities. If you are an owner and want to provide further information about your box, please let me know.
Why do this? Because it feels good to help find ways to share books and food with others in our communities. Hunting boxes down and fixing the map is fun - it's like "Pokémon GO" with a purpose. Happy hunting!
If you want to take an existing user-made map and edit it, simply go to the map (using the Chrome browser) and in the upper left corner in the legend you'll see an icon with three vertical dot, to the right of the name of the map. Click that and you'll see "Copy map" as a choice. Click that and a new tab will open and your copy will eventually appear. You could try it on the book boxes map or farmers market map, if you like.
One annoying feature is that if you hit "delete" or "backspace" when editing, you will inadvertently delete the pin. You can undo such deletions by hitting Control-Z on Windows (Command-Z on the Mac).
By default, you have one "subgroup" at the top that includes all your pin locations. The "Add layer" button in the "Legend" area at the left lets you make a new subgroup, just as I have a subgroup for book boxes and one for micro-pantries. Also note the "Base map" area at the bottom of the Legend. You can choose a different style by clicking on the little arrow to the left of these words and choosing one. Me, I prefer the Terrain look, in the upper right of the grid of possibilities - a bit busy, perhaps, but cool.
Once your map is ready, you can share it with the public: on the map itself, in the legend on the left, there's a Share link near the top. If you Preview the map, you'll see a long link you can share, something crazy like https://www.google.com/maps/d/u/0/viewer?hl=en&mid=1ldz1Y5R_7F_8nMdE5zOT4NK2Fz-pMgNP&ll=42.3981057020408%2C-71.13707414999999&z=13. I recommend making a short, sane, link using bit.ly or other free service. In bit.ly you click "Create" then paste your link into the "paste long URL" box. It will provide you a random short link. But you can do better! In the "customize back half" box you can change the random string after the "bit.ly/" part to whatever you like. Many names will already be taken, many will not - figure out something short and sweet (and all lowercase is also nice).
If you have any tips on how to better make maps, please let me know and I'll add the information here. A much more serious guide for professional developers is also available - I haven't dared to touch that.
