A Fresh Cup of Zip
An article I wrote that describes how to take advantage of the zip classes included in Java’s 1.1 JDK. This includes some very simple programs that can create, view, and extract from zip files.
Fast String Searching With Suffix Trees
This article describes a relatively painless way to construct suffix trees. Once you have a suffix tree constructed, it is extremely easy to search for the longest match of a given string. This makes the suffix tree a nice data structure to use in macro replacement forms of data compression.
Xing AudioCatalyst
AudioCatalyst is a commercial program that creates and playsback MP3 files. The recorder can rip tracks from music CDs and convert them to MP3 files in many different formats. A trial edition of the product is available at this web site.
Modifications of the Burrows-Wheeler Data Compression Algorithm
by Balkenhol, Kurtz, and Shtarkov. A paper that was published at DCC 1999. Some thoughts about BWT and the context tree model, alphabet modification, modification of MTF, and Grouping of symbols.
NOTE:The file type would indicate that this is a compressed file, but it actually appears to be unencoded PS format.

Information about JPEG images
ACB 2.00c
George Buyanovsky’s ACB archiver. The proprietary compression scheme used by ACB gives consistently impressive compression ratios. Those ratios come at the expense of much RAM and CPU time.
AMG Version 2.3
The docs say it all: der ultimative FREEWARE-Packer. Yes, the internal documentation for this archiver is in German, but users limited to English should still be able to figure this program out.
ARJZ 0.15 alpha
This appears to be a freeware archiver. I’m unable to give more information; all the documentation is in an unkown language. Any reader who is able to translate is invited to improve on this description.
ARQ Crusher! Archive Utility v3.2
This is an archiver that appears to have been designed with the DC Micro Development Crusher! Library. No documentation in the package, I’m assuming this is freeware.
ARX (R) archiving utility v 1.0
Another shareware archiving utility.
ASD - archiver version 0.1.4
A freeware archiver from Sweden. Versions available for DOS, Windows, and Linux, with Win9x long filename support. Includes source for extraction from ASD archives.
DCL user feedback: Finally i found what I was looking for, a freeware archiver for both Windows, Dos, and Linux!
Another user said: Offers What I waslooking for, very helpful.
BOA Constrictor Archiver v0.58b
Packing program BSA 2.00
Archiving program that advertises support for DOS, Windows, NT, OS/2, QNX, and UNIX. This distribution has no docs, but the ACT page indicates that this is shareware, so until further notice I’ll label it as such.
BVI 1.7 - Single file compressor/decompressor
This is freeware with no source. The docs claim a fast algorithm with arithmetic coding.
AIN Archiver v 2.3
Full-featured archiver AIN, the extracting utility AINEXT and the EXE-files compressor AINEXE. Compression/extraction methods used in the AIN archiver excels noticeably those used in any well-known archivers, such as ARJ, LHA and PKZIP, in both the compression rate and the performance.One user who rated this product for the DCL said Super Product!
The Piecewise-Constant Image Model
Caravian has developed a proprietary compression algorithm for palettized images. They claim substantial imporvement over conventional GIF compression. Their web site has an ActiveX plug-in for demonstrating the technology, but it isn’t clear exactly what they are selling. The site is rather vague about specifics.
Welcome to compression consulting
Michael Schindler’s home page for his business, which appears to be consulting in the field of data compression. His home page has a description of his business, as well as links to some informative pages he supports.
Practical Huffman Coding
A page by Michael Schindler that describes Huffman coding in a fair amount of detail. Also includes links to other information resources. This page also has an explanation of the canonical huffman table storage algorithm.

Ioannis Kontoyiannis
Ioannis Kontoyiannis is an Assistant Professor at Purdue. He has many of his papers available on line, in PS or PDF format, often both. Sample title: Pointwise redundancy in lossy data compression and universal lossy data compression..
Higher Compression from the Burrows-Wheeler Transform by Modified Sorting
A paper by Brent Chapin and Steve Tate describing some improvements in BWT compression. The abstract says that compression can be improved by alphabet ordering and reflecting the sorted binary strings. This version is in PDF format, a PS format is available as well.
Telvox Software Shop
This site has links to Telvox’s CODEC package, which appears to ship in both free and commercial versions. CODEC uses proprietary lossless compression, and is ported to a wide variety of platforms. Telvox is located in Bologna, Italy, and has duplicate web pages in English and Italian.
