The Library Cryptids:
Any public or school library is liable to come down with a case of Library Cryptids. I had heard vague whisperings around the reference desk of such things. Creatures who lurked in the library but whose existence could not be proven. Creatures who change the daily lives of patrons, librarians and aides everywhere, but who seldom escape credulity. Like a dream that sits just outside of the edge of sleeping they are there, Hanging out in the chaos of the Children's section by day, for who would believe a child that claims that the book nipped at her, or the bean bag chair smiled and winked when she passed. But at night all the things they get up to!
There are many varieties of Library Cryptid, in fact probably too many to mention, and just like local cryptids "The Beast of Bloomfield" the "Terror of Tuberville" many have yet to be officially cataloged. Should you be ever blessed into the Sanctus Sanctorum of the Holy Guardians of The Books, behind the Circulation desk, you might find a small group of be-sweatered ladies off to one side trading hushed comments over sips from their oversized water bottles. The stories they will whisper about odd creakings in the stack at closing time, or arriving in the morning to find "anomalies" in the stacks, or flickering centipedes in the cataloging, a single large print novel lying prone on the floor of the reading room, spine cracked, will shake your faith what you perceive as the "known world".
Let us begin now with our list of the most common of the Library Cryptids.
First there is the unpleasantness of the Shelf Shifter.
The primary job of the shelf shifter is to move the library "stock". Now it can work subtly, for instance one day you can come in and all the R's are neatly arranged over five shelves with space for outwardly displayed covers, the next day they are all jammed vice- like onto two shelves and you might need a chisel to separate them. You simple came to quickly shelve a copy of Phillip Reeve's Mortal Engines but now you will need to retake by force what has now become the sloppy spaced "S"s to shelve this book. Sometimes the Shelf Shifter is more direct and decides to just drop a clip or two out of the bookcase so that when an unsuspecting elderly patron reaches for Thomas Newcastle's Treatise on Ptolemaic Mathematic. (Yes, I know your library doesn't have that one, whose would.) Yet when they reach for this book an avalanche of Archimedes and Pythagoras fall upon them with the kind of force that can only be generated by such truly heavy material. A doctoral student discovers the splayed body of the septuagenarian crushed by the weight of knowledge.
Then bane of the Cataloguer's existence: The Record Wrecker
The Record Wrecker is a newer hybrid of the ancient genus The Card Catalog Creep which has been mutated by the "this fxcking computer" virus. Moving away from it's original paper habitat, the Wrecker is now able to occupy digital space. In it's purest form it is the most elusive of creatures, appearing only before the weary eyes of the Library Cataloger, however it's ill effects can spread through out Circulation like a plague. It is a devourer of information, nibbling out little bites of biographical information, snacking on subfields, eating away identifying markers of all kinds and then leaving as its excrement jumbled call numbers, and incorrect subject headings. The Record Wrecker is the reason that when you enter the subject "vampires" into the patron catalog it spits out the resulting title "Life of a Soda Can". It is also the reason that a book of poetry from Byron ends up with a shelf label of 599.6 (The Dewey decimal number for Land Ungulates. I do not know what those are, but they are certainly not synonymous with "She walks in beauty".)
Generally many of the Library cryptids are able to live in some form of non-lethal, although annoying, symbiosis with it's host library, this next category however is not to be trifled with. I shudder even to name the individual creatures of the species, and so refer to them merely as "the Destroyers". Ranging in height from first shelf to uppermost case the Destroyers are capable of book murder most foul.
Those in the Children's section are especially adapted to crayon and marker mayhem. They have one leg shorter that the other and walk with an uneven limp dragging their crayon/marker fingers in circles around the book. If resting on their haunches they might use these fingers to scribble bright red, blue and green across pages of text and illustration, or use the illustrations as a coloring book. Unfortunately, due to their limited control of small muscle movements are unable to stay in the lines.
The next closely related subspecies exists mostly in the Non-Fiction section, there fingers are more developed and sophisticated, some with sharp appendages that spit ink, honed to underline passages and create non-helpful, annoying marginalia that distracts and confuses the patron. The worst however are those with the neon yellow excrement that shite in straight lines across paragraphs of non-essential information. There must be some sort of relationship between these two subspecies as they often work in concert with one another to make an entire tome unreadable.
And then there is the Rippers *shudder*. Rippers seem to hatch and gain early substance by eating the corners of the book where they have been dog eared by poorly trained readers. As they mature so do their appetites devouring whole pages, gluing pages together with their vile excreta, and flossing their teeth with the threads of spine stitching until whole folios fall lose from the bindings.
The Destroyers are the truest banes of the book world. I can bear to describe them no longer.
Having devastating but non lethal consequences we come to the species of Library cryptids so ubiquitous that they have long been discredited and put down to human error. This fierce creature has been known to all library peoples since before the days of the Library of Alexandria. The Monster of the Mis-shelving. Monster may be too sharp a word, they are not venial, like the the Library Leaking Pipe, or the Fearsome Spine breaker, they are simply lazy. Oh yes, it's easy to blame the pages and aides and I am sure mistakes are made, but truly even the most inept of student helpers is helped by this beast. The Monster of Mis-Shelving is a curious beast, it receives sustenance by licking jelly splodges, and cracker crumbs from oft read texts. You would think it would have a lot of energy since one of it's main forms of fodder is coffee stains, but alas it is assumed that the physiology of the Mis-shelver is not reactive to caffeine. It is a lazy beast, pursing by, witnesses have stated, a long sensitive probiscis sniffing for any mislaid food crumbs, climbing the ladder of the bookcases, it thumbs haphazardly thorough the collection, picking a book at random, eating and placing it back to the nearest open space at hand.
As you might surmise their taste for spilled food leads them to spend most of their time in the picture books, where sticky handed little monkey fingered kids leave enough food detritus behind to make a cockroach fat. This is the reason that not a single library anywhere in the world has neatly organized alphabetical collection of picture books.
This easily accessed buffet does not mean however they do not have an occasional bout of epicurean fondness for adult books, and can be found disorganizing books across the whole of the collection. Seemingly innocuous at first encounter, within the span of one semester, if unchecked, with decimate all order, making it entirely impossible for any patron to find the tome they desire. With this I tip my hat to the fearless squad of library aides, pages and helpers that fight the daily battle against their spread.
This is of course merely a short collection of some of the more common Library Cryptids. It is important as Cryptobibliographists we continue to record our encounters with these creatures. Unlike Nessie and Bigfoot, a large enough compendium of sightings has yet to be assembled to cement the certain hood of the library cryptid in the public imagination. If there is no certainty we will not be able to secure the necessary funding for research, discovery and ensure archival conservation. That is why we need you, as library workers and patrons to add to this assemblage of information. May we move forward in our work to understand the world of chaos creating creatures one cryptid at a time.
