The Voynich MS - Bibliography and references

For printed publications, and all references used at this site, see below.

Internet resources


It is not possible to present a complete or even a representative list of internet resources about the Voynich MS. The following is an overview of sources I am aware of, that are either important or interesting for one reason or another. I welcome information about missing or broken links (1).

The Beinecke Rare Book and Manuscript Library of Yale University

The first and foremost resource is that of the Beinecke Rare Book and Manuscript Library of Yale University:

Yale University Press has issued >>a very affordable photo facsimile with accompaying essays about the MS, in October 2016.

Yale also provides a >>summary overiew of the book.

In addition, an expensive, hand-made replica of the Voynich MS has been commissioned to the spanish company Siloé, who are experts in the reproduction of old manuscripts. 898 numbered copies will be offered for sale. The price is expected to be around 8000 Euros.

Before the availability of the digital scans, the library provided printout copies of an early B/W microfilm made of the MS to interested researchers (the so-called "copyflo").

Discussion boards

I present the following links to discussion boards and blogs, in order to provide access to different opinions about the Voynich MS.

The inclusion of any link does not imply that I endorse its contents. To the contrary: I strongly object to offensive statements that are not about the Voynich MS, but about people (also, but not only me) and institutions, that may be found in some of these fora or sites.

I am aware of four active fora, two of which are personal web logs (blogs) but they stand apart in that they have a diverse group of regular commentors from all over the world. In chronological order of their starting date:

Blogs - in English

Blogs - other languages


There are Wikipedia entries about the Voynich MS in many different languages, confirming the interest that the MS enjoys worldwide. Links to the English and German ones are given below, and one may reach the versions in other languages through these. Some dedicated wiki's and wiki books have been started, but these seem to have been abandoned.

>>The Voynich MS entry in the general English Wikipedia.

>>The Voynich MS entry in the general German Wikipedia.

Herb identification

The tentative identification of herbs in the Voynich MS has always been a topic of special interest, which is witnessed by the number of dedicated sites:

Other sites with general information

There are innumerable web sites that copy or reformulate information about the Voynich MS available elsewhere. I don't consider it either possible or interesting to attempt to list them all here. The web sites below all have some original content.

Jim Gillogly's original FTP site is probably the earliest site dedicated to the Voynich MS, with some files of historic interest. This link has disappeared long ago, but Jorge Stolfi has provided a >> mirror site.

>> Jim Reeds' site (mirror by Jorge Stolfi) has the most complete bibliography, and further essential general information about the MS.

>> Jorge Stolfi's site presents his analysis results. Included among these are some of the most important, if not ground-breaking analyses of the Voynich MS text. He also makes available all scripts used in these. Furthermore he has another list of links to on-line Voynich MS material.

The most convenient way of browsing the Voynich MS is by using a >>tool developed by Jason Davies called the Voynich MS Voyager.

A >>Voynich Query Processor (>> alternative address) by someone known as "Job" looks like a very promising development.

I would also like to recommend this >>text extraction tool by E.Schwerdtfeger.

The >> site of Philip Neal, with a vast amount of reference material for the history of the Voynich MS, which I am referring to very extensively.

>> Rafał T. Prinke's Voynich MS pages with emphasis on the history of the MS during the reign of Rudolf II of Bohemia and a rebuttal of the suggestion that Dee had anything to do with the MS. Also includes biographical information about Wilfrid and Ethel Voynich.

Edith Sherwood presents several of her theories in well-presented web pages, for example:

This >> wiki at the Universite of Adelaide presents a very interesting statistical analysis of the Voynich MS text.

A >> site of Sean Palmer. Additional pages of interest not (yet) linked there are:

The >> web site of Colin MacKinnon has a unique collection of documentary evidence related to Wilfrid and Ethel Voynich, and Anne Nill.

An extentensive web site by Jan Hurych with many articles on many topics: >>Entry page, and >>List of articles.

A >>wiki-style web site by a mailing list member know under the nickname Knoxmix, with his anaylses of the Voynich MS text.

Xavier Ceccaldi used to have detailed background information about the Collegium Romanum and the Villa Mondragone. The original site is closed, but I am hosting a complete and unmodified copy of it here, with his permission.

>>Dennis Stallings' site holds a collection of historical precedents of the manuscript and a description of some of his analyses.

Berj Ensanian maintains the >>Journal of Voynich Studies in which he and a handful of other participants analyse a vast number of details directly or indirectly related to the Voynich MS.

>>Takeshi Takahashi's site is one of the largest web resource about the Voynich MS, written in Japanese. This site also has available his complete >> transcription of the VMS.

>>John Grove

>>Vladimir Sazonov

>> John Baez

Some tentative solutions and theories

Gordon Rugg explains his theory that the Voynich MS was made by Edward Kelley using Cardan grilles, as published in Cryptologia, January 2004 (new link needed).

There are two independent attempts to link (among others) the astronomical pages in the Voynich MS to celestial events:
A >>blog by Robert Teague
An >>analysis by P.Han.

A very decorative >>site presenting a tentative solution to the Voynich MS, in French and English.

>>Dan Gibson

>>Don Hoffman
