Cannot Be Digitized #4: The Problem with Papyrus

This week's blog entry is dedicated to the late Traianos Gagos, world-renowned papyrologist, who passed away sometime on Monday.  I didn't know the man personally all that well, but his passing has left a gaping hole in the academic community at the University of Michigan.  He will be missed.

Papyrus is an interesting material.  It was one of the scant few plant-based paper products in the ancient world, and, when it wasn't being used to compose such lofty things as epic poems and bills of sale on particularly cranky mules, it served a wide variety of non-literary purposes.  Papyrus was (and still is) used in numerous genres: corpse preservation, haberdashery, roofing, netting, baskets, rope, and mats, just to name a few.  It's an incredibly versatile plant, but when historians attempt to explain the shift away from papyrus scrolls to codices made with parchment (a paper product made predominantly from goat and sheep skins), they tend to emphasize how brittle it is, how susceptible to moisture and aridity, how rough its surface is, and how generally unwieldly the long strips used to make scrolls were.


Most of the papyrus in the ancient world came from Egypt, so it's not exactly a shocker to discover that one of the biggest finds in the history of papyrology took place in Oxyrhynchus, a town in southern Egypt named after the species of fish said to have eaten Osiris's wiener.  Along with Herculaneum in the shadow of Mt. Vesuvius, it is the source of the vast preponderance of papyrus fragments that exist and likewise of most discoveries of "new" classical texts, which may seem like an oxymoron (har har).  What I mean is texts we knew probably existed at some point but for which there were no surviving copies, like Sophocles' Ichneutae, which has the dubious distinction of being one of the most peculiar satyr plays in existence.  It is neither particularly bawdy nor particularly funny.  Sophocles always was a bit of a downer.  Surely, several individuals at our fine university could talk your ear off about all this (they're on the second floor of Angell Hall--no, not the philosophers...), but I wish to address something a little more pertinent to this blog, their digital afterlives.

While I have in the past taken issue with the "sky is falling" rhetoric of the digitizers (I mean no disrespect; some of my best friends are digitizers, which I realize reads just like "some of my best friends are black"), in the case of ancient papyrus it truly is apt.  William Biers, a professor of Colleen's from the University of Missouri (our mutual alma mater), often tells the story of a dig some graduate student participated in where he was carrying an amphora full of papyrus scrolls.  He, the graduate student, dropped the amphora, and when it hit the ground, the texts shattered soundlessly into a pile of dust.  Whoops, sorry history; our bad.  So when optical scanning came on the scene as a genuine means of digitally preserving documents, papyrus was one of the first things subjected to it.  Alas, we may lose the papyrus, but we'll always have Paris... err, the image!

WRONG!  The problem with papyrus is not only do you have to know dialects of ancient languages most people have never even heard of, the script on a significant number of scraps is barely legible to the naked eye, and magnification was often hardly of any assistance.  One of the feats digitization did permit, however, was the ability to run the images of the fragments through various after effects processes, like photoshop filters, to up the contrast and to improve legibility in ways not possible with just the document itself.  But it was with the development of high intensity x-ray scanning that legibility of ancient documents improved immensely, not just in terms of reading the "visible" text but also palimpsest, text scraped away so the paper could be re-used.

In terms of relative purchasing power, books have never been cheaper, so it is perhaps hard for us to imagine that you'd want to reuse a book; we just recycle or throw them away.  But re-using a physical document is not merely limited to wiping away what it was and making something new of it.  Sometimes, texts are already inscribed with more than we can see, and it is incumbent on us not to be so arrogant to think we know all that it is and can be.  As the more recent x-ray scanning demonstrates, it is important to keep those ancient things with us, so that we might return to them, so that we might see them again with what we have learned.  Traianos was fond of opening public lectures with the claim that most papyrus fragments are boring, are receipts, are tallies, are well-deserving of returning to the rubbish heaps of Oxyrhynchus where they were found.  In a way he was right, but in a way he was also very wrong.

Whose Text is it Anyway?

Welcome!  There are two of us creating Libral Thinking and so with a second voice, the second post commences. I, Colleen, am currently a graduate student in the School of Information, and I am working "in the field" as it were, both sitting at a reference desk, and answering patrons' questions through a chat program on the internet.  I hope to be able to add some insights into the practical and professional side of the messy nature of working in collections at this uneasy "transition" time.  (Is it a transition?  Will we keep the books?  --questions for another time.)  For today I take up the topic of the uneasy relationship for the text and the institution created in the space between the physical book on the shelf in a collection and a digitized version (copy?) on the web with access provided through Google Books.

To use Google Books, a person must type "Google" into a browser of some sort.  Each page of the book scanned by Google bears their mark, seen to the left.  It is fairly clear that it is a document scanned and provided by Google, presented by Google through their interface (and their copyright settlement).

Yet, there is a tricky problem:  The same text is marked very clearly with the institution where a physical copy (at one point?) was housed.  In the case of Essays of an Ex-Librarian by Richard Garnett, 1901, it bears a large bookplate identifying the University of Michigan. 
As a "remote reference librarian" I sit in my living room answering questions that pop-up through chat programs from patrons typing on the library website. I have already fielded multiple questions from patrons around the world asking questions resembling the following:

Patron:  Page 193 is blurry, can you scan it for me and e-mail it?
Me:  There is a button in Google's interface to report the page unreadable.
Patron: Come on...It's just a page. Can't you go get it?  At least read it to me?
Me:   No.
Patron:  Pretty please?
Me:  No, but you can request the book through Inter-Library Loan.
Patron:  But, it's just a page, and I'm in Poland.  That would take a month and I'd have to pay.
Me:  No.

Okay, okay, some of that is a lie already.  In fact, I have, on my own time, requested books to be brought over from the Buhr storage library on my own account, and I have photographed the requested page with my own digital camera and e-mailed the photo to the patron.  There is no policy for handling such requests since they are not frequent enough as of yet to be a problem.  In general, our affiliated patrons come first, but with any time left I can choose to help.

What should the response be to these types of questions?  Whose text is it when the digital scan belongs to a company providing access, but yet it never loses its association with its referent, physically housed in another place, but containing the same content?  The combination creates a lot of assumptions.  The person typing usually assumes that I am in the library, that the book still exists in the library, that it is a few feet away from me, and that it will "just take a minute."  They also assume that it is our (my) responsibility to help them, and not Google.  Maybe that is a good thing?  The library is seen as more available, and helpful than Google. The physical item in this case is more accessible since a bad scan cannot be re-scanned.

But, what do I do though when there are three other chat windows open simultaneously and it's the second Google verification request of my shift?  As the face of a "public" research university, who is my patron?  Should I have levels?  Shouldn't the students come first?  How does a local or state institution fund reference services for a public that through those bookplates and our availability on the web becomes a global audience?    Does the whole library become a reference for the digital in that we should make plans duplication charges like for a closed-stack special library?  Are physical books now a "Special Collection" in relation to the digital?

These questions cannot just remain fuzzy since the digitized texts constitute the memory of our culture.  In some sense we all own them since the memories in the texts lie in the spaces between people, sustained by references to the texts each time we read one, think about it, and add it to our store of knowledge that we share with others as we live and chat over coffee.  For now (most of) the physical books that Google references remain in the libraries, but many people unable to see the blurry details behind "the cloud" call for the practical destruction or selling-off of the books and their pricy buildings and air-conditioning as a practical necessity, not seeing the physical servers, fiber optic cable, and software with quick obsolescence upon which a digitized collection such as Google Books collection relies.  We must define our relationship, and take ownership and responsibility for it, or just like the stack of corroded 51/4 inch floppy disks that hold the games my father programmed for me that sit next to a failed Commodore PET disk drive in my closet, the entirety of our cultural memory could become inaccessible while we pay attention to shinier things.
