Sciencemadness grows a decent library

Polverone - 3-2-2004 at 23:07

The much-neglected <A HREF="">Sciencemadness library</A> has acquired a major new section. There is now a <A HREF="">page</A> devoted to English-language scientific and technical books acquired from the Digital Library of India.

I have already done the following:
-downloaded all high-resolution images for the books in question, using a Python script and some patience
-run automated median-filtering on the images to clean up speckling and make them compress better
-begun cleaning page images and converting to OCR'd PDF files

The most time-consuming part of all this is the hand-cleanup of dark page edges, speckles, and blotches in Photoshop. However, I have already completed two books: The Practical Methods of Organic Chemistry and The Synthetic Use of Metals in Organic Chemistry. Go and grab them now, and look forward to many more books being completed in the following months. If there are any volunteers to do hand-cleanup of images for other books, it would be appreciated. Good short summaries or other comments for the "comments" column on that page would also be nice.

Holy! Thumbs up! :)

We all love you Polverone:D

Finally, for some reason some of the books I wanted from the DLI wouldn't download for me. They kept timing out or something would always go wrong. Very agrevating to have such a plethora of information just out of your finger tips. Sure I could of read off the site, but it is extremely time consuming to change pages, and nearly impossible to search the document.

Thankyou very much Polverone :D

I tried downloading some books myself which I would then convert to a PDF but as Mumbles said, the pages kept timing out :(

book added: Ozone

Polverone - 4-2-2004 at 23:25

Ozone, by E.K. Rideal, 1920, 204 pages.

Like a number of other DLI books, this one appeared to be scanned relatively poorly (or perhaps the source book was in poor condition). The light, noisy images on many pages make it hard for humans to read and virtually impossible for OCR to decipher. The compression ratio also suffered from the noise, making the file considerably larger than those from other books of ~200 pages.

book added: Vitamins

Polverone - 10-2-2004 at 15:22

Vitamins by Ragnar Berg, 411 pages, is now available.

I'm still working at it!

Biochemical Catalysts in Life and Industry by Jean Effront, 1917, 753 pages, is now available. I have attended to other projects for quite some time before finishing up this latest release. Let me remind my fellow mad scientists why these old books are so wonderful:

They are very concrete, and their practical observations are useful even if their theory is far behind the times. They do not rely on unusual/expensive equipment or reagents. They contain information that is often glossed over in more accessible modern texts, since the modern texts want to present modern theory, which displaces old theory and practical information of all sorts.

It has been a while since I posted to this thread. I can't remember where else I may have been announcing books, or maybe I just haven't been announcing them.

There are now 5 new books in the library. Thanks go to Chromium for posting the source PDFs that I processed to create these files. The books are Autoclaves and High Pressure Work, The Electrochemistry of Organic Compounds, Formaldehyde, Fixation of Atmospheric Nitrogen, and Organometallic Compounds.

I get a "file not found" on this link.

Polverone - 17-3-2006 at 03:10

It started out with the main "Library" page consisting of member-submitted articles and article summaries, but the collection of scanned books quickly eclipsed it. Eventually the dlibooks page was made the main index, with the small collection of shorter articles relegated to another page.

Ok. Also just FYI but I get a file not found for:
