(i simply have javascript instruct my domain to have python go get the file, which it can do, and then i have python store it on my domain, and then -- since it's now on my domain -- javascript can get it.) but javascript coders shouldn't have to do this two-step shuffle. and they won't, if you have snowy authorize cors requests... -bowerbird

i hart you

james, yes, you have discovered that marcello cares more about fighting the indiscriminate downloading robots than taking care of the real humans... but something tells me angel michael is entertained by the notion that there's "indiscriminate scraping" of p.g. e-texts. but i suppose that, as the lead dog -- (a little sledder talk for newby) -- gutenberg.org gets lots of headwind. so... just choose one of the mirrors! i'd suggest that greg can point you to a certain mirror that's more in line with the assured-access that don remarked should be associated with an endeavor like this one founded by michael hart, an attitude i'd guess rubbed off on greg. because i'll personally attest that urllib is working just fine to grab files from it. but, if i might suggest an improvement, greg, could you authorize c.o.r.s. for it? (at least it appears to me it ain't working.) i'd need nothing more than "get" access, which i think poses absolutely no danger. but also, greg, just to avoid cors hassles, maybe i should re-request one of those accounts you so often promise to people. (but feel free to embargo any javascript i'd serve until you could verify its safety.) i'm about to (finally) make some big moves, and although i no longer feel any need to include project gutenberg, my hart is not so cold that i feel a need to exclude it either. so if you want to come along for the ride, just crawl in the back seat. and buckle up. -bowerbird

Re: [gutvol-d] [Sugar-devel] Problems downloading PG titles without a web browser

Daniel, Thanks for your tips. I was able to add a user agent string like this: OLPCReader/1.0; +mailto:nicestep@gmail.com and that fixed the problem. The code has been committed to Git and I'll release a new .xo file shortly. I don't know that I'll submit a path for network.py as the user agent string is not a problem for most uses.

Proposal for augmented structure for PG
by Jon Hurst 12 Feb '13

12 Feb '13

I would like to propose an augmented structure for PG. The aim of this structure is to realise Greg's stated desire to include ebooks that are contributed outside of the normal WWer workflow. The basic premise is that the PG library as it stands becomes just one of multiple contributor libraries hosted by PG, with the gutenberg.org interface rejigged to catalogue all of these libraries. In terms of customer interface, the customer gets a searchable catalogue of works. When they access a work, they are presented with a list of which contributor libraries contain expressions of that work, each with some blurb describing the properties of that expression. Thus, for example, the "Huckleberry Finn" page might list two expressions in the WWer library, one in the DP library, one in the Adcock library, an RST derived one in the Marcello library and a ZML derived one in the Bowerbird library. Library owners would be responsible for maintaining their own libraries. Anything in any of the libraries is fair game for other contributors to build on. Contributors may choose to pool resources and maintain common root versions/ master formats, e.g RST advocates might maintain a set of RST files in Mercurial, possibly even grouping together to build a common RST derived library. Customers would be able to list all the books in a particular library, so if they thought the Bowerbird "Huckleberry Finn" was the best formatted ebook they have ever seen they would be encouraged to see what other Bowerbird ebooks there were. If they thought it was awful, they would avoid Bowerbird works in the future. You could even allow customers to blacklist certain libraries from their future results. Library owners would also get the ability to recommend expressions in other libraries to anyone who is visiting their library, creating a useful reputation chain. The WWers should not be upset as nothing is being erased. They have the biggest library, and they are already entirely responsible for its maintenance. It is already maintained to strict standards, and if those standards stack up, it should be the go to library. DP should be pleased. They would get to do CSS3 and make their own epubs if they want to, and they would get to maintain their own library, something that has been talked about wistfully on the DP forums for a _long_ time. Individual contributors should be pleased. They can produce work to specifications driven by their own beliefs in the formats that they believe are superior, and if they are right about the quality of their work being superior, they will garner a following.

Problems downloading PG titles without a web browser
by James Simmons 12 Feb '13

12 Feb '13

I had created an Activity for the One Laptop Per Child project which downloads and reads the Plain Text version of PG titles. I use the offline catalogue and some Python code to list available titles in the catalogue that match a search string. For instance the child might enter "Twain" and get a list of all the books by and about Twain. Then the child can download the book using the same program. This has been working well for years but lately it has stopped working. When I try to debug it I see it trying to download this URL for instance: http://www.gutenberg.org/dirs/1/1/119/119.zip Put this URL in any web browser and it will download "A Tramp Abroad" by Mark Twain. However, try and download the same URL using my Python code and you get this: Forbidden You don't have permission to access /dirs/1/1/119/119.zip on this server. ------------------------------ Apache Server at www.gutenberg.org Port 80 My Activity is a much more convenient way of downloading books than a web browser. For one thing, it gives the downloaded file a more intelligent name than 119.zip. I would like for it to work again as it did before. Suggestions? James Simmons

fixing markup problems
by David Griffith 11 Feb '13

11 Feb '13

I've recently started reading Project Gutenberg works in epub format. Here and there I've noticed problems in markup[1]. I would like to correct these, but the FAQ just talks about correcting typographical errors. How can I help? [1] For instance in Aesop's Fables, there are often links to a fable found just before the fable's actual title. -- David Griffith dave(a)661.org
