Our past is as important as our future.

  • Beta text site (and 1937 NEC)

    We’ve pivoted a bit from doing full digital restorations to simply getting people basic access to this material. Here’s what that means going forward:

    We’ve been using our sources to input the text of each edition to Markdown files, and have been crafting a website to make this text viewable. You can find that beta website at read.thesparkive.org. We have a few editions up, and are always working in the background on more versions.

    Some of the text is being sourced from original documents, but some are being sourced from sister publications, like Rules for Electric Light and Power Equipments by Associated Factory Mutual Fire Insurance Companies. Since there was no state-level enforcement of electrical codes back in the early 1900s, these requirements were used by insurance companies to guide their customers on what sorts of installations they were willing to insure. As such, the National Electrical Code was often reprinted by insurance companies, along with additional commentary that the respective insurance company found important.

    So basically, the text should be accurate, but some of the formatting or reference notes may be different. We’ve noted the source for each edition so it’s clearer for folks.


    Aside from that, we’ve begun making rough scans to upload for people to enjoy, since the actual digital restorations are very time-consuming. Ultimately we’d like to share those digital restorations as purchasable books as well, but there’s no sense waiting to share reference scans in the meantime.

    We’ve just uploaded the 1937 National Electrical Code, and as we gain access to other physical books, we’ll scan and upload those, as well. These are fairly rough, and the books we have access to have varying levels of quality, but they’re definitely readable, so we hope you enjoy.

  • 1905 version finished!

    1905 version finished!

    Had enough time over Christmas break to finish restoring, OCR’ing, and fully linking the 1905 National Electrical Code.

    Remember back when we had a brief period where NFPA sold searchable PDFs with internal linking? Basically, if there was a reference to another part of the code, you could click on that reference and it would jump you immediately to that part of the document. It’s fantastically useful as an offline research tool, and we’ve upgraded the 1905 NEC to take advantage of it.

    Restoration Process

    The scans we were working with had varying levels of quality, in addition to the original book having a number of stamps and markings from previous owners. We did our best to remove everything that was the consequence of time, to restore the original as it was printed, as well as enhance the contrast of some of the weaker stamped pages and/or overactive noise reduction with the original scans.

    There is more that could have been done with dewarping/deskewing many of the pages, but the text is now readable and formatted consistently. This is something we’ll get better at with future editions.

    Some of the scans weren’t cropped at all, which posed some fun challenges.

    Overall, we’re very pleased with this first outing. The next restoration will likely be the 1930 NEC, since that just hit public domain last year, and it will be fun to get the contrast of 25 years of code changes.

    Please download and enjoy!
