Hanover Historical Texts Collection : History Department : Hanover College The Hanover Historical Texts Collection makes available digital versions of historical texts for use in history and humanities courses. Search by keyword, or browse the listings below. The faculty and students of the Hanover College History Department initiated the Hanover Historical Texts Project in 1995, at a time when few primary sources were available outside of published anthologies. To make primary texts readily available for classroom use, they selected important documents, scanned print versions that were out of copyright, converted the scans into HTML format, proofread the resulting documents to correct OCR errors, edited them to provide page breaks, page numbers, and bibliographical information, and posted them online. We have since expanded the collection to include transcriptions of manuscript material from the Hanover College archives. Most of the texts in the Hanover Historical Texts Collection are in public domain. Ancient Greece and Rome Medieval Europe Early Modern Europe

Contribute to our library Gnostic Society Library: Sources on Gnosticism and Gnosis Almost all of the several dozen internet sites with collections of texts similar to our own obtained their material by directly or indirectly copying some files present at the Gnosis Archive. Ours was perhaps the first major collection of such texts to appear on "the web" in 1994, and thus has served as a source for others creating "their own" collections. Unfortunately transcription errors, typos, and primitive HTML formatting were present in the massive amount of material added to the Gnosis Archive in our first years; in a repeated process of "copying" they have been very widely propagated around the internet. Over nearly two decades we have made many corrections to these texts. It appears that few of the sites copying material from this collection have taken the time to read, edit and correct the texts! This is of course exactly how the manuscript tradition has propagated errors in the past centuries, though with vastly different technologies of reproduction.
