What is this
The aim is create a webpage where the USER can generate a custom-made brand new VOLUME of the Borges' Library of Babel (complete with its 410 pages of charater permutations...)
- TEST SITE go on have a try!!
To create a PDF from Javascript alone, I've used jsPDF. Unfortunately though, jsPDF does not have a lot of styling possibilities. There are other tools that can be added to work together with jsPDF for better styling, like fdpf for instance, but for my purposes I haven't explored this so much.
What could be done/added:
- secretly add a word or phrase in some page of the book. Preferably a prhase pciked out randomly from a list, and added randomly to a page. (not all books will have this. Say, it could be only books downloaded on an odd/even second)
- Make a better, nicely designed start page: I don't need to show a preview. Just have a BIG button saying "Get your volume now" or smthing, and the information text (see Background below).

Background
In Jorge Luis Borges’ famous Library of Babel the universe consists of a vast quantity of books, containing all that can ever be expressed in language.
The Library is total and its shelves register all the possible combinations of the twenty-odd orthographical symbols (a number which, though extremely vast, is not infinite): in other words, all that it is given to express, in all languages. Everything. […] Each book is of four hundred and ten pages; each page, of forty lines, each line, of some eighty letters which are black in colour. […] All the books, no matter how diverse they might be, are made up of the same elements: the space, the period, the comma, the twenty-two letters of the alphabet.
This webpage generates an example of how one full volume in this Library would look like, by combining the 25 characters in a quasi-random order, resulting in a unique book on each run.
The resulting volume is ultimately constrained by the web-browser algorithmic logic, which can be seen as a human limitation, (“Man, the imperfect librarian,”) a flawed attempt to mimic the divine combinations with the hope of chancing among the meaning to the universe, answers to eternal questions of humanity, “the catalogue of catalogues,” or our life’s vindication:
A blasphemous sect suggested that the searches should cease and that all should juggle letters and symbols until they constructed, by an improbable gift of chance, these canonical books.
Note on alphabet
Borges provides no clear information on which twenty-two letters he had in mind. Perhaps it is a reference to the number of letters of the Hebrew language, so dear to him as student of the Kabbalah, but in this case the inclusion of the period and comma is problematic. I have chosen to use the Classical Latin Alphabet (composed of 23 letters), minus the Y, which was a late addition, and does not figure in Old Latin. This remains a conjectural and idiosyncratic choice nevertheless.

<p>In Jorge Luis Borges’ famous short story <i>The Library of Babel</i> the universe consists of a vast quantity of books, containing all that can ever be expressed in language. Each volume in the library is unique, although they all share the same format:</p>
<p class="q">The Library is total and its shelves register all the possible combinations of the twenty-odd orthographical symbols (a number which, though extremely vast, is not infinite): in other words, all that it is given to express, in all languages. Everything. […] <b>Each book is of four hundred and ten pages; each page, of forty lines, each line, of some eighty letters which are black in colour.</b> […] <b>All the books, no matter how diverse they might be, are made up of the same elements: the space, the period, the comma, the twenty-two letters of the alphabet.</b></p>
<p>This online-work generates an exemplar volume based on Borges' descriptions, by combining the 25 characters in a quasi-random order, resulting in a unique book on each run which can be easily downloaded in PDF format. This newly-minted volume is ultimately constrained by the web-browser algorithmic logic, which can be seen as a human limitation (“Man, the imperfect librarian”), a flawed attempt to mimic the divine combinations with the hope of chancing among the meaning to the universe, answers to eternal questions of humanity, “the catalogue of catalogues,” or our life’s vindication:</p>
