Alpha Portland Cement Company Blueprints and Concrete Plans These came in a folder that I found in an old box of maps and blueprints from an architect's estate.  Although not a book, they are in the public domain and interesting so I thought I would post some crude copies. I have not edited them or cleaned them up, and there is some loss to the margins on most of them because they were a bit too large for a scanner.   The actual plans are almost all there, though.  I figure anyone who is interested can clean them up after download if need be (although they are perfectly usable as they are now).   I have posted them at very high resolution (about 6500 by 4500 pixels) to preserve details and lettering. I gather this series, all from 1920-1920, was an effort by the Alpha Portland Cement Company to promote the use of concrete and cement in building.   I think I have almost a complete set here, but I have no definitive reference as to what plans were included. As always, these high resolution JPEG  images are all free of charge and ready to be downloaded one at a time or in bulk via a ...

While the purpose of this site is to provide free images for you to do with what you please, some people have been interested in merchandise and products that are ready for purchase and do not require downloading, uploading, formatting, resizing and all the other fun details involved with putting the images on a real item rather than a web page. Please feel free to take the images and use them to make your own products or any other purposes. However, if you wish to see the pre-made products available for purchase, many of which use pictures from this site, you may browse the Zephyrus Books Old Book Art gallery at Zazzle. Any purchases you make of these products has the added benefit of helping to support this site. which is never a bad thing.

Why Does the Site Exist? Simply to share public domain resources.  Zephyrus Books comes across a lot of antiquarian books with wonderful old illustrations in the public domain.  Many of these are not available for public sharing anywhere on the internet, at least not in an easily accessible or larger scale format, so this site was started as a free resource for anyone looking for out of copyright images. Are There Any Fees of Costs At All? No, unless you choose to make a voluntary donation. Why Would I Want to Donate? To offset site costs.  While this site is in no danger of disappearing, there are ongoing hosting costs and labor to scan, clean up and research good images.  Even a few $10 or $25 donations per month make a substantial difference in the budget. Are There Restrictions On How I May Use the Images? No.  Commercial or personal use for any purpose is perfectly fine.  We post only public domain content and as such cannot put any restrictions on it.   Even though we have scanned it and perhaps edited it, the changes are not substantial enough to warrant any claim to any proprietary interest.   We love getting credit and links, though.   Please see the "About" ...

Well, now everything actually has been transferred to the Gallery, including about 100 "orphaned" images I found on my site which had not been linked to previously. Please continue to give me any feedback about how this new site looks to and works for you. I appreciate all input and will continue to tweak things to make it work better. I have added a translator box now which I hpe will help any non-English reading guests. I will "de-stickify" this post soon. - John

This site was started in October of 2007 with the intent of sharing out of copyright images from books that passed through my bookstore, ZephyrusBooks. com. The number of books I have cataloged, while still under a hundred, has grown remarkably, and in the summer of 2008 I moved to this new blog format with the images supported on a separate gallery. I have expanded the material somewhat to include things I have not scanned myself. This is mostly material that other people have shared with me, but also may include material from sources with online archives such as the Library of Congress. Examples include some world maps and the work of David Roberts. While these are sometimes available elsewhere, there is often a fee involved, or the resolution quality is low, or they are archived in a format that is hard to access for many people. They also often need extensive editing or cleaning up, which I have done to make them as ready to use as possible. While this site remains a sideline, it has taken a lot of time. I am always happy to receive feedback or help, in the form of ...
