It's unlikely I'll get back to updating this site on a regular basis. If you are looking for a newer, more active source of similar news, please check out the recently announced foss4lib.org.
pymarc is a python MARC handling library that's been around for a while but hasn't been written up here before. You can download it from pypi or easy_install it too, and if you want to hack on it you can grab it from LaunchPad using bazaar.
The latest tar is attached.
From the writeup on the home page: "pyCatalog is a Python, MySQL, wxPython, Reportlab application specifically usable in library and information centers. It simply produces book catalog and card catalog in pdf format rendered using reportlab. The program takes MARC file as its source data. pyCatalog - is a combination of Python, wxPython, Reportlab, and python-mysql application that renders Book and Card Catalog."
Tarballs of the linux build and source for 1.3 are attached.
From the MOAI site: "MOAI is a platform for aggregating content from different sources, and publishing it through the Open Archive Initiatives protocol for metadata harvesting. It’s been built for academic institutional repositories dealing with relational metadata and asset files. The MOAI software can aggregate content from different sources, transform it and store it in a database. The contents of this database can then be published in many separate OAI feeds, each with its own configuration. MOAI is a standalone system, so it can be used in combination with any repository software that comes with an OAI feed such as Fedora Commons, EPrints or DSpace. It can also be used directly with an SQL database or just a folder of XML files.
...the MOAI software makes it as easy as possible to add or modify parts of your repository (OAI) services stack. It tries to do this without sacrificing power, and encouraging the re-use of components."
I remember when pyoai first came out a few years back, I think there were some zope integration components alongside it. It's great to see that this project is still in use and still being improved.
More details about getting it and installing it are on installing MOAI page, and a copy of the 1.0 source tarball is attached.
Prospero is a mostly-gone-but-not-forgotten ILL/DD toolkit that ran into, um, *ahem* problems with its 2.0 release. If you sift through the history of posts here about Prospero, you'll find more details about how it evolved, but not a copy of the software. Attached to this post is a copy of the 1.40 release, for the completist library hacker in your ilfe.
Tellico is another one that's seen steady improvements since the last post about it here. The latest version is 1.3.5, and release notes for this and prior releases are on the project's home page, which also highlights the variety of binary distros available.
A 1.3.5 source tarball is attached.
Copies of the server bundle, windows staff client, and OpenSRF corresponding to this latest release are attached.
Koha has also had some big releases since last mention here. The full story on Koha 3 is here, and the latest release is Koha 3.0.1, with lots of bugfixes and improvements.
A local copy of Koha 3.0.1 is available here.
According to the Greenstone3 page, this major rewrite is "a complete redesign and reimplementation of the original Greenstone digital library software (Greenstone2). When complete, it will retain all the advantages of Greenstone2 - for example, it will be multilingual, multiplatform, and highly configurable. It incorporates all the features of the existing system, and is backwards compatible: that is, it can build and run existing collections without modification. Written in Java, it is structured as a network of independent modules that communicate using XML: thus it runs in a distributed fashion and can be spread across different servers as necessary. This modular design increases the flexibility and extensibility of Greenstone. Please note, Greenstone3 is our research version of Greenstone, and is still incomplete, and not stable. For a production digital library we recommend using Greenstone2."
Distributions of the 3.x release line are available on that page, and a source tarball of Greenstone3 is cached here also.
