With the popularity of the recent post on catalogers who blog, I'm encouraged to pull together a similar list of catalogers and metadata librarians who actively use Twitter. So, I'll work on that.
In the meantime, Becky Yoose did a great write up about her Twitter list of cataloging and metadata librarians: A year of troublesome catalogers and magical metadata fairies. She captures the spirit of catalogers using this social networking tool to communicate among themselves and with others: cataloging questions, problems, rant, snark, coffee, chocolate, etc.
So, join in and have fun. Twitter really has turned out to be the professional development tool du jour!
