_lognostics produces a range of software tools for vocabulary acquisition researchers. All the programs you can download from this page are on-going research tools, and should be treated with appropriate caution. The software is freely available, without charge, in exchange for critical assessments of how the software performs. We welcome your feedback and comments. Most of the downloads are supplied in the form of .zip files. You should download the files you need onto your computer and unzip them into a directory called c:\lognostics\xxxx - where xxxx is the name of the program (e.g. c:\lognostics\X_Lex). The zip files contain manuals which describe how to use the programs in more detail. Some of the programs run directly over the Internet. You can run these programs by clicking on the yellow RUN button. These programs do not need to be downloaded.

The small print
You use the software on this page at your own risk. _lognostics does not accept any liability arising from the use or misuse of this software.

Please note that the downloadable programs are all designed to run under Windows, and we don't support other platforms (yet). Most of the programs will run under Windows98, Windows2000 and WindowsXP, but we don't have extensive testing facilities, so if you are using an unusual Windows system, the programs may not work. Please let us know if this happens to you. You should also note that the programs are designed to run on stand-alone desk-top machines. Some of them will run over a network, but we don't design the programs to work in this way, and the programs may not function properly in a network environment.

We will respond to any reasonable requests for technical help but please bear in mind that our resources are finite, and we may not be able to respond immediately.
