Other Free software

• MarcEdit -- MarcEdit 4.5+ is the latest and greatest version of the MarcEdit family. It's basically a free, complete MARC editing package that includes an XML API for dealing with XML data, a Z39.50 client and lots of MARC editing functions. Follow the link to take a look.
• SMTP Emailer -- This is a command-line application only. I use it on my server at home, in conjunction with a script, to notify me when something suspicious is occurring.
• Winsock Library -- This is a very simple library that wraps a number of the Winsock API into 6 easy calls. For those of you that use VB, this library will allow you do distribute your application without the Microsoft Winsock Control. Though I always would recommend learning how to manipulate low level Winsock API, this library does save some of the headaches.
