===INTRODUCTION===
----
The Noisebridge Digital Archivists group is for anyone interested in a range of topics including book scanning, digitizing video/audio, open access, creative commons, and more. Lately we have focused on bound book digitization. 

We usually meet on '''Wednesdays at 7pm'''. Join the mailing list and send us an email to see if there's a meeting this week.

----
The Noisebridge book scanner was recently demonstrated at the 2015 Maker Faire in San Mateo

===MAILING LIST===
----
Many weekly updates are made exclusively on our mailing list. Please join to keep in touch and ask questions:

Join the mailing list here: [http://www.noisebridge.net/mailman/listinfo/digitalarchivists digitalarchivists]

A summary of topics in our mailing list will be posted soon.

===HARDWARE===
----
Our first project was to build a book scanner at Noisebridge based on the open-source [http://diybookscanner.myshopify.com/products/diy-book-scanner-kit DIY Book Scanner] design. Check out the schematic, below, to see all the components. You can build your own using inspiration and guidance from this [http://www.diybookscanner.org/archivist/ open source design] [http://www.diybookscanner.org/DIY%20Book%20Scanner%20920.zip from simple cut plywood] or order [http://store.diybookscanner.org/ pre-fabricated kits], though they are in demand and often sold out.

===MECHANICAL OPERATION===
----
Our style of book scanner is intended for use on bound books that can be sufficiently flattened by pushing the book up to the platen glass. Although the process requires turning each page by hand, one page at a time, the book is not damaged by process. Affordable automated book scanners are being developed by [http://linearbookscanner.org/ Dany Qumsiyeh]. Note there is some risk putting your rare book on an automated scanner unattended such as ripped paged, etc.

<u>Please see this animation to illustrate the manual process:</u>

[[File:BookScanHand_Quick.gif|Page Turning]]

Each time the page is changed a trigger is hit by the operator to capture images of the even and odd pages simultaneously from SLR cameras. By capturing two pages at the same time our model has a speed advantage compared to flatbed scanner enabling us to scan about 600 pages an hour for a skilled operator.

===SOFTWARE===
----
The device captures from both cameras simultaneously by using USB drivers provide by gphoto2 wrapped into a nice python script [https://github.com/danyq/diybookscanner here]. Check out gphoto2 [http://gphoto.org/ here] and the list of supported cameras [http://gphoto.org/proj/libgphoto2/support.php here]. If you have linux you can just type: sudo apt-get install gphoto2


Currently we are making simple scripts to perform Optical Character Recognition (OCR) and produce searchable full text as PDF documents [https://github.com/andrewdefries/TesseractOCR Github Code Repository]. Check it out and fork our repos.

===CURRENT BOOK SCANNING PROJECTS===
----

<u>Digitization of the Mycological Society of San Francisco collection</u>

*Danny Newman, librarian for the [http://www.mssf.org/ Mycological Society of San Francisco], will be digitizing the journal and book collection of the Mycological Society. 

<u>The Pesticide Files</u>

*Andrew Defries PhD has been creating a custom assembled and rare digital corpus comprised of bound books on the topic of pesticides used in agriculture. Please see the github front page for a detailed description [https://github.com/andrewdefries/ThePesticideFiles The Pesticide Files]. This corpus will not be made available for download or public use, though access may be granted in the future via collaborative research agreements.
