RoboFab is a library of Python code for manipulation and storage of font and glyph related data. RoboFab implements a new font file format, the Unified Font Objects or .ufo for short. UFO is a format for font sources (similar to something like .fog or .vfb) except that UFO is XML based (see Glyph Interchange Format), readable, well documented and easily extended to contain different kinds of data.

Like a modern code version of the mythical beast with 100 serpent heads, Typhoeus runs HTTP requests in parallel while cleanly encapsulating handling logic. To be a little more specific, it’s a library for accessing web services in Ruby. It’s specifically designed for building RESTful service oriented architectures in Ruby that need to be fast enough to process calls to multiple services within the client’s HTTP request/response life cycle.

The dateutil module provides powerful extensions to the standard datetime module, available in Python 2.3+.

Logbook is a logging sytem for Python that replaces the standard library’s logging module. It was designed with both complex and simple applications and mind and the idea to make logging fun:

This online exhibit draws attention to the unique and diverse artwork of bookplates in the Stanford University Libraries’ collections.

While many need light-filled rooms for inspiration, he wanted to avoid large windows opening onto a residential neighborhood and sought a cave-like atmosphere to disappear into his work. Subtle light was brought in by other means when the architect built a dome above his client’s desk (which Price describes as similar to the rotunda of the oracle’s temple at Delphi) and filled it with the books he uses the most. Davis whimsically calls the space his “Navajo kiva of knowledge.”

Modernizr is an open-source JavaScript library that helps you build the next generation of HTML5 and CSS3-powered websites.

The following tool-lending libraries allow library patrons to borrow tools, equipment and "how-to" instructional materials, usually free of charge.

Parcon is a parser library. It can be used for parsing both normal text and binary data. It's designed to be easy to use and to provide informative error messages.

Pargen, which is provided as a submodule of Parcon, is a formatter library. It's much the opposite of Parcon: while Parcon is used to parse text into various objects, Pargen is used to format objects into text. As an example, if you wanted to reimplement Python's json module, you would use Parcon to implement json.loads and Pargen to implement json.dumps.

Static, which is also provided as a submodule of Parcon, is a static typing library and Python object pattern library. It lets you build patterns that match Python objects based on their type, their attributes, certain properties such as whether or not the object is a sequence, the types that make up the object's values if the object is a sequence, and so on.

"What Middletown Read" is a database and search engine built upon the circulation records of the Muncie (Indiana) Public Library from November 5, 1891 through December 3, 1902. It documents every book that every library patron borrowed during that period, with the exception of one gap from May 28, 1892 to November 5, 1894.

Internet Archive is building a physical archive for the long term preservation of one copy of every book, record, and movie we are able to attract or acquire.  Because we expect day-to-day access to these materials to occur through digital means, the our physical archive is designed for long-term preservation of materials with only occasional, collection-scale retrieval. Because of this, we can create optimized environments for physical preservation and organizational structures that facilitate appropriate access. A seed bank might be conceptually closest to what we have in mind: storing important objects in safe ways to be used for redundancy, authority, and in case of catastrophe.

The goal is to preserve one copy of every published work. The universe of unique titles has been estimated at close to one hundred million items. Many of these are rare or unique, so we do not expect most of these to come to the Internet Archive; they will instead remain in their current libraries. But the opportunity to preserve over ten million items is possible, so we have designed a system that will expand to this level. Ten million books is approximately the size of a world-class university library or public library, so we see this as a worthwhile goal. If we are successful, then this set of cultural materials will last for centuries and could be beneficial in ways that we cannot predict.

After many years of planning and other projects to complete first, we have finally gotten around to my dream of creating a traditional victorian library. When complete, the walls will be wrapped in velvet, drenched in dark leathers and woods, and topped off with an oak wall-to-tall bookcase with a sliding ladder. There will be a globe in the corner that is actually a bar, tufted leather chairs that would be suitable for Gatsby himself, and a record player powered with glass tube amps.

Provides the most natural and robust way of dealing with date/time values in Python.

For more than 20 years, from the 1960s until the 1980s, librarians at the Milwaukee Public Library clipped hundreds of recipes from the Milwaukee Journal and Milwaukee Sentinel. These recipes were heavily used at Ready Reference to answer telephone questions relating to various recipes. Before recipes were readily available on the internet, someone in the Milwaukee area looking for a particular recipe or cooking technique would call Ready Reference.

These clipped recipes form the nucleus of the Historic Recipe File digital collection. Many of Milwaukee’s favorite foods appear in the recipes in this collection. This collection provides a fascinating glimpse into the local and ethnic foods that were popular in Milwaukee from as long as 50 years ago.

AA-lib is a low level gfx library just as many other libraries are. The main difference is that AA-lib does not require graphics device. In fact, there is no graphical output possible. AA-lib replaces those old-fashioned output methods with powerful ascii-art renderer. Now my linux boots with a nice penguin logo at secondary display (yes! Like Win95 does:) AA-lib API is designed to be similar to other graphics libraries.

The Airborne Sound library has over 16,000 sound effects featuring luscious ambiences, International as well as North American signature recordings, planes, trains, industrial effects and machinery and much more.

Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window System, Quartz, Win32, image buffers, PostScript, PDF, and SVG file output. Experimental backends include OpenGL, XCB, BeOS, OS/2, and DirectFB.

Cairo is designed to produce consistent output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension).

The cairo API provides operations similar to the drawing operators of PostScript and PDF. Operations in cairo including stroking and filling cubic Bézier splines, transforming and compositing translucent images, and antialiased text rendering. All drawing operations can be transformed by any affine transformation (scale, rotation, shear, etc.)

This desk is a recycling of books. This photograph does not do justice to how lovely it looks. It is very tactile and appealing.

Libraryhack is a mashup and apps competition with great prizes designed to encourage the creative and innovative re-use of library data and digital content.

The competition is being run by the National, State and Territory libraries of Australia and New Zealand. (NSLA)

musl is a new general-purpose implementation of the C library. It is lightweight, fast, simple, free, and hopefully correct in the sense of standards-conformance and safety.

PoDoFo is a library to work with the PDF file format. The name comes from the first letter of PDF (Portable Document Format). A few tools to work with PDF files are already included in the PoDoFo package.

The PoDoFo library is a free, portable C++ library which includes classes to parse PDF files and modify their contents into memory. The changes can be written back to disk easily. The parser can also be used to extract information from a PDF file (for example the parser could be used in a PDF viewer). Besides parsing PoDoFo includes also very simple classes to create your own PDF files. All classes are documented so it is easy to start writing your own application using PoDoFo.

The BiblioBouts Project is funded by the Institute of Museum and Library Studies. Researchers at the School of Information (SI) of the University of Michigan (U-M) have partnered with the Center for History and New Media (CHNM) at George Mason University to conduct the BiblioBouts Project, a 3-year project (October 1, 2008 to September 30, 2011), to support the design, development, testing, and evaluation of a computer game to teach incoming undergraduate students information literacy skills and concepts. The BiblioBouts information literacy game is a pervasive and unobtrusive presence beside the online tools and collections students use to do their assignments. We are testing to determine whether a well-designed game can break students of their habitual research patterns: Google and the web. We want our game to be efficient and fun, and have the ability to scale from one classroom to hundreds.

It’s a design by the architects at Peter Gluck and Partners. The building is a cube, measuring 20-feet on each side. The interior space mesures 720 square feet. It’s not a house, but serves as a library for a private collection of 10,000 books on Japanese history.

The lower level is reported to be the primary storage space for the books. The upper level is a light-filled open space with fully opening windows.

The first thing that came to mind when I saw this design is that it could also serve as a secure cabin, albeit with some modifications to the open upper level. For example if one were to add sliding steel window covers and reduce the number of windows this little building could be sealed up like a fortress when the owner was away.

jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.

Berkelium is a BSD licensed library that provides off-screen browser rendering via Google's open source Chromium web browser.

It takes advantage of Chromium's multiprocess rendering to isolate browsers from each other and can render to any buffer in memory. The user of the library can inject input and javascript code into web pages to control them, as well as listen for events generated by the page such as navigation events, load sequence events and paint events. Berkelium provides a small API for embedding a fully functional browser into any application.

Adaptagrams is a library of tools and reusable code for adaptive diagramming applications, for example: drawing tools, automated document and diagram layout, smart presentation software, graph drawing, chart layout, etc.

Currently, the Adaptagrams repository includes:

* libvpsc — a solver for the Variable Placement with Separation Constraints problem. This is a quadratic programming problem in which the squared differences between a placement vector and some ideal placement are minimised subject to a set of separation constraints. This is very useful in a number of layout problems.
* libcola — a library for constraint graph layout. Specifically, force-directed layout using the stress-majorization method subject to separation constraints. Applications include layout with non-overlapping nodes and clusters, directed graph layout and layout preserving the crossing properties of a given starting layout.
* libavoid — a cross-platform C++ library providing fast, object-avoiding connector routing for use in interactive diagram editors.

In Episode 10 of the GAMBIT Research Video Podcast Series "FUN IN THE STACKS: GAMES, GAMING AND GAMERS IN LIBRARIES" Syracuse Assoc. Professor and the host of "Board Games With Scott", Scott Nicholson leads a discussion during the Nov 11, 2010 GAMBIT Research Meeting on the value of gaming programs in public libraries.

One role of many libraries is to serve as a community center where people living in the same area can meet and enjoy activities together. Games, as the next new media, are quickly being integrated into library services as an offering for groups of users who may not frequent the library for other reasons. As with any phenomenon, scientists wish to understand more about this intersection of gaming and libraries. In order to explore games in libraries, researchers from the Syracuse University School of Information Studies, the American Library Association and the University of Illinois at Champaign-Urbana are working together.

The Curt Teich Postcard Archives, part of the Lake County Discovery Museum, is recognized throughout the world as the largest public collection of postcards and related materials.

"Uncertain Futures" began as an attempt to explain the explosion of science fiction on the American literary scene in the first two decades of the cold war era. …Previous histories of American science fiction have given too much weight to the bomb and the cold war, and not nearly enough to other explanatory factors: the postwar economy, the paperback book, and the self-organizing tendencies of science fiction fans. This exhibit (and the academic paper on which it is based) are an attempt to add these important pieces to the puzzle, without discounting the explosive impact of the bomb and the cold war on the rise of American science fiction.
This exhibit is also an experiment in digital humanities. It tries to be two things:
1. A useful starting point for both casual readers and historians interested in science fiction or the intersection of history and popular culture.
2. A serious historical argument, based on primary source research, in a novel and engaging format.

Lighthouses were often time located in remote areas and as such had no access to city services such as libraries, opera houses, entertainment, etc. that most people enjoyed who lived in a town or city. As light keeping was a lonely profession in most cases supplies were brought to them by lighthouse tender ships. One of the items the tender supplied was a library box on each visit as pictured to the left. Library boxes were filled with books and switched from station to station to supply different reading materials to the families.

Polymaps is a free JavaScript library for making dynamic, interactive maps in modern web browsers.

The H.M.S. Challenger Expedition, conducted between 1873 and 1876 was one of the first, and perhaps the most thoroughly documented, of many expeditions devoted to the investigation of ocean physics and biology. All of the 90-odd Zoology and Botany reports published by the Expedition have been digitized and are available here for browsing. The reports include over 30,000 pages of text and many thousands of illustrations.

Mapstraction is a library that provides a common API for various javascript mapping APIs to enable switching from one to another as smoothly as possible. Developers can code their applications once, and then easily switch mapping provider based on project needs, terms and conditions, and new functionality.

Users can switch maps as desired based on personal taste and quality of maps in their local area. Various tools built on top of Mapstraction allow users to easily integrate maps into their own sites, and configure them with different controls, styles, and provider.
Why Mapstraction?

Mapstraction additionally fills some holes each provider's current offerings (taking advantage of existing open source solutions where possible) to normalise the feature set across platforms. Mapstraction also uses OpenStreetMap for people who want to build maps without restrictions on derived works.

What works and doesn't work in Vermont's Libraries

vertex.js is a graph database inspired by filesystems that supports automatic garbage collection and is built on node.js and tokyocabinet. It uses HTTP as it's communication protocol and JSON as it's request and response data format. Vertex.js is schemaless allowing it to naturally model arbitrary graphs and irregular data.

Openframeworks is a c++ library designed to assist the creative process by providing a simple and intuitive framework for experimentation.

The library is designed to work as a general purpose glue, and wraps together several commonly used libraries under a tidy interface: openGL for graphics, rtAudio for audio input and output, freeType for fonts,freeImage for image input and output, quicktime for video playing and sequence grabbing.

The code is written to be both cross platform (PC, Mac, Linux, iPhone) and cross compiler. The API is designed to be minimal and easy to grasp. There are very few classes, and inside of those classes, there are very few functions. The code has been implemented so that within the classes there are minimal cross-referening, making it quite easy to rip out and reuse, if you need, or to extend.

Simply put, openFrameworks is a tool that makes it much easier to make things via code. We find it super useful, and we hope you do too.

‡biblios is an open-source, web-based metadata tool for libraries

Windows actually can replace a DLL that is in use by renaming the original then copying the new file into place. However, the Windows world prefers not to do this. Why?
Even if you replace a file that is in use, there may still be code in the system that wants to use the old version. For example, suppose you have two files, A.DLL and B.DLL, which work together. You issue a patch that updates both of the files, but A.DLL is in use. No problem. You simply replace both of them. As a result, programs that were still using A.DLL keep using the old version, but new programs will use the new one. And all programs get the new version of B.DLL.
Now a program that was using the old A.DLL decides to call a function in. It naturally expects the old version of B.DLL, but instead it gets the new version. Depending on what sort of change you made to B.DLL, this call may work—or it may crash. Both DLLs assume that its partner comes from the same matched set.
Even if you're updating just a single DLL

This project provides a Python package that creates an environment for graphics applications that closely resembles that of the Processing system.

Now anyone and everyone can create apps and mash-ups using library data from WorldCat, the world's largest library catalog. Because the WorldCat Basic API is here!

This new API is a simplified version of the WorldCat Search API. Send it RESTful URI queries in OpenSearch, and it retrieves results in RSS or Atom. The WorldCat Basic API can support up to 1,000/queries per day for noncommercial use.

igraph is a free software package for creating and manipulating undirected and directed graphs. It includes implementations for classic graph theory problems like minimum spanning trees and network flow, and also implements algorithms for some recent network analysis methods, like community structure search.

Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction.

Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

Planning Shifts of Library Collections

Wouldn’t it be a little magical if, when you signed up for a new site, the site said something like, “We notice you have a profile photo on Flickr and Twitter, would you like to use one of those or upload a new one?” I built a JavaScript library that can help you do just that. Ident Engine discovers and retrieves distributed identities and user-generated content to help you build a little magic into your user interfaces.

The Python Pubsub package provides a publish - subscribe API that allows data to be sent between independent parts of your application. For instance, between the GUI components and the Application Controller. Using publish - subscribe in your application can dramatically simplify its design and improve testability. I liked the following summary by one user on the wxPython mailing list:

Basically you just have some part(s) of your program subscribe to a particular topic and have some other part(s) of your program publish messages with that topic. All the plumbing is taken care of by pubsub.

Syntactic sugar for creating Python command line scripts by introspecting a function definition

NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.

It would be a decade before I would encounter my first great library. By “great library” I mean a library whose holdings are so huge that no one quite knows what is in its basements; a library in which Vivaldi scores may lie hidden for a hundred years; a library of density as well as scope; a library that will turn no book away—trash or treasure—for a good library is miserly, as proud of its relics as a church, permitting even a cheap novel to be useful to the study of the culture it came from, an institution, consequently, that won’t allow ephemera to ephemerate and is not ashamed of having the finest collection of bodice-rippers in existence; a library that has sat safely in the same place and watched like a sage its contents age, consequently a library whose dust is the rust of time; a library that never closes on cold days and will allow the homeless to rest in its reading room; a library that will permit me to poke about in its innards as long and as often as I like.

For libraries, the awkward fact is that such thefts can be extremely difficult to notice. Detective Sergeant Vernon Rapley, a police officer with 23 years’ experience, has for the past eight years headed the Metropolitan Police’s Art and Antiques Unit.

Rapley and his squad of three full-time officers recover on average £7m worth of stolen and laundered art and antiques (including books) each year, with items looted from Iraq a recent priority. Rapley also founded the London Museum Security Group (including libraries), which meets regularly, complementing initiatives such as the Antiquarian Booksellers’ Association’s e-mail alert of books stolen from its members.

Chordial is an open source implementation of MIT's Chord DHT algorithm <http://en.wikipedia.org/wiki/Chord_(DHT)> in the Erlang programming language. Chordial allows key lookups over networks of computers, large or small. This allows developers to use it as a building block for higher level applications such as distributed file storage or task dispatching.

qooxdoo is a comprehensive and innovative Ajax application framework. Leveraging object-oriented JavaScript allows developers to build impressive cross-browser applications. No HTML, CSS nor DOM knowledge is needed.
