I am probably the worst genealogist in the world when it comes to research logs and keeping track of where I have searched, especially when it comes to recording IGI batch numbers. Luckily groups like Nuestros Ranchos and the Asociación de Genealogía Hispana have done a wonderful job in parts of Mexico (thank you Nuestros Ranchos), and other Latin American countries (thank you AGH) to record batch information.
I was teaching my students this last week about wikis, and we talked about the FamilySearch Wiki and all the good it's doing, but it also got me thinking. Wikis are designed for mass authoring or contributors. Depending on the wiki and how it's set up anyone coming to your site or anyone that creates an account can help build content, or facilitate a group of people working on a specific project.
The wheels started turning; I have always been troubled by the fact that there isn't one good repository/website that lists IGI batch numbers for all of Mexico...so I created an IGI Mexico batch lab /experiment. I created a wiki for anyone can use and/or contribute to; it's found at: http://mexicoigibatchnumbers.wetpaint.com/
All you have to do to contribute a batch number is to create an account, which is free, then you can add batch numbers to your heart's content. The more people that contribute the better and more complete the batch number collection will be. For those of you new to wikis and/or to wetpaint, I recommend going through the video tour, which is made available once you create your account. You will be amazed at how easy it is to add stuff to the wiki.
