That's what we bought and what he encouraged. He even encouraged for groups of the class to throw in on one and photo copy the pages to share.

Had he known about these sites to download them for free, I'm positive he would have just told us about those. They may not have existed then though.

We were in that weird time when internet was becoming a normal thing for everybody.

https://en.wikipedia.org/wiki/Library_Genesis

Library Genesis (Libgen) is a file-sharing based shadow library website for scholarly journal articles, academic and general-interest books, images, comics, audiobooks, and magazines. The site enables free access to content that is otherwise paywalled or not digitized elsewhere.[2] Libgen describes itself as a "links aggregator", providing a searchable database of items "collected from publicly available public Internet resources" as well as files uploaded "from users".[3]

Libgen provides access to copyrighted works, such as PDFs of content from Elsevier's ScienceDirect web-portal. Publishers like Elsevier have accused Library Genesis of internet piracy. However, others assert that academic publishers unfairly benefit from government-funded research, written by researchers, many of whom are employed by public universities, and that Libgen is helping to disseminate research that should be freely available in the first place.[4]

Libgen is blocked by a number of ISPs in the United Kingdom,[15] but such DNS-based blocks are claimed to do little to deter access.[4] It is also blocked by ISPs in France,[16] Germany,[17] Greece,[18] Belgium (which redirects to the Belgian Federal Police blockpage),[19] and Russia (in November of 2018).[20][21]

https://en.wikipedia.org/wiki/Z-Library

Z-Library (abbreviated as z-lib, formerly BookFinder) is a mirror of Library Genesis,[1] a shadow library project for file-sharing access to scholarly journal articles, academic texts and general-interest books (some of which are pirated). Most of its books are from Library Genesis while some of them are uploaded directly to its site by individuals. Individuals can also contribute to the website's repository to make literature accessible to as many people as possible. As of 22 October 2021, Z-lib states that it possesses more than 8,930,000 books and 84,830,000 articles.[2] According to the project's page for academic articles (at booksc.org), it claims to be "the world's largest e-book library", as well as "the world's largest scientific articles store". Z-library also describes itself as a non-profit organization sustained by donations.[3]

History The footer in the project's pages contains the phrase "Free ebooks since 2009."[4][5] Z-Library is one of the better-known shadow libraries, along with Sci-Hub and Library Genesis, with publishers and government organizations usually putting the three in the same category (intellectual property theft) when pursuing anti-piracy cases.[citation needed] UK organization The Publishers Association has attempted to enact internet service provider-level blocks on Z-Library.[6][7]

In late 2015, Publisher Elsevier filed a successful court request that ordered the registrar of bookfi.org to seize the site's internet domain.[8] Bookfi.org, booksc.org and b-ok.org were included in the 2017 Office of the United States Trade Representative report on Notorious Markets.[9]

Functionality Unlike Library Genesis and Sci-Hub, not much is known about Z-Library in terms of its operation, management, commercial status and mission statement. Notably, Z-Library does not open its full database to the public.[citation needed]

In an effort to prevent blacklisting of domains (oftentimes by internet providers at the DNS-level in accordance with legal procedures), Z-Library uses a homepage at a memorable domain. The homepage does not contain any infringing content but instead lists working mirror domains, which Z-Library has multiple of for different regions. These domains can be switched and do not need to be as memorable. For instance, some include numbers.[10]

Z-Library Team claims to have servers in Finland, Germany, Luxembourg, Malaysia, Panama, Russia and the USA, and the size of their database is over 220 TB.[11]

Librarians and the Z-Library Librarians have been largely professionally silent about the Z-Library.[citation needed] One exception, by Mikael Böök, library activist, is the essay "Herding the Wind: A journey to the strange world of the e-library in the autumn of the year 2020". Böök connects the purpose of Z-Library to the five laws of library science by S. R. Ranganathan. He also notes Michael S. Hart, inventor of the e-book and founder of Project Gutenberg as a precursor of the Z-Library. Böök addresses issues of copyright, the perplexing case of books by Wu Ming, and the roles of the World Trade Organization (WTO) and World Intellectual Property Organization (WIPO).[12]
