This study analyzes ACRLog (the ACRL Blog) by its content. Using the stratified random sampling technique, 277 posts were selected from a total of 991 posts sent to ACRLog from September 2005 to November 2010. These 277 posts are grouped by subject and by author’s status (academic, librarian). Differences in subjects by years and by authors are examined. In addition, word frequencies in the posts were calculated and the most used words and noun phrases determined. Differences in the use of these words and noun phrases by years and by authors are also analyzed.
